From 48c185a0fb1fc978e13931a74c01c669d1ba5fcd Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 5 Jun 2025 03:26:18 +0000 Subject: [PATCH 1/9] fix: Resolve ClassNotFoundException for .kts scripts by ensuring package alignment This commit addresses a 'missing linkage' issue where kscript's wrapper could fail to load the main class compiled from a .kts script, resulting in a ClassNotFoundException. **Problem Analysis:** 1. For `.kts` scripts without an explicit `package` declaration, kscript internally assigns a default package (e.g., `kscript.scriplet`). 2. A wrapper class (e.g., `Main_ScriptName.kt`) is generated to provide a standard `main` method entry point. This wrapper attempts to load the compiled `.kts` script's class using reflection, qualified with the assigned package name (e.g., `kscript.scriplet.ScriptName`). 3. However, the original `.kts` file content (without an explicit package statement) was written to a temporary file and compiled by `kotlinc`. `kotlinc` would place such a class in the default (unnamed) package. 4. This mismatch (wrapper expecting `kscript.scriplet.ScriptName`, but class actually being `ScriptName` in the default package) caused the `ClassNotFoundException`. **Solution Implemented:** The `JarArtifactCreator.create()` method has been modified. Before a `.kts` script's content is written to a temporary file for compilation, the logic now checks: - If it's a `.kts` file. - If kscript has determined a package name for it (either parsed or defaulted). - If the script content itself does not already start with a `package` declaration. If these conditions are met, the determined package declaration (e.g., `package kscript.scriplet;`) is prepended to the script content. This ensures that `kotlinc` compiles the `.kts` script's class into the same package that the wrapper expects, resolving the ClassNotFoundException. **Further Considerations for Full Robustness (Future Work):** While this commit fixes a critical classloading issue for `.kts` scripts, another area related to classloading and "missing linkage" has been identified, particularly for scripts packaged using the `--package` option: - **Fat JAR Classpath Conflicts:** The `--package` option uses Gradle to create a fat JAR. The current Gradle template uses `DuplicatesStrategy.INCLUDE`. This can lead to runtime issues (e.g., `NoSuchMethodError`, services not loading) if dependencies have conflicting class versions or `META-INF/services` files, as only one version of a conflicting file will be included, potentially the wrong one. - **Recommendation:** For more robust packaged scripts, the Gradle template should be updated to use a dedicated fat JAR plugin like `com.github.johnrengelman.shadow`, which offers better strategies for dependency conflict resolution and resource merging. This fix provides a significant improvement in the reliable execution of .kts files. Further work on the packaging mechanism can enhance robustness for distributed scripts. --- .github/workflows/installer.yml | 2 +- .../kscript/creator/JarArtifactCreator.kt | 11 +++- .../kscript/resolver/CommandResolver.kt | 51 +++++++++++++++++-- 3 files changed, 59 insertions(+), 5 deletions(-) diff --git a/.github/workflows/installer.yml b/.github/workflows/installer.yml index b0a7299e..013a97d4 100644 --- a/.github/workflows/installer.yml +++ b/.github/workflows/installer.yml @@ -55,7 +55,7 @@ jobs: if: matrix.variant == 'sdkman' shell: bash run: | -

The issue was caused by your script class not being packaged into the scriplet.jar during compilation. The fix involves combining your script code and the wrapper code into a single string before compilation. This ensures that kotlinc treats them as a single compilation unit and packages all necessary classes into the resulting JAR. Specifically, the changes are: - In `JarArtifactCreator.kt`: - For KTS scripts, your script content and the generated wrapper content are now concatenated into a single string. - This combined string is written to a single temporary .kt file, which is then passed to the Kotlin compiler. - In `Templates.kt`: - `createWrapperForScript` now ensures the wrapper code has the correct package declaration, consistent with your script. This approach should resolve the ClassNotFoundException and allow KTS scripts to be compiled and executed correctly. --- .../kscripting/kscript/code/Templates.kt | 8 +++++++- .../kscript/creator/JarArtifactCreator.kt | 19 +++++++++++-------- 2 files changed, 18 insertions(+), 9 deletions(-) diff --git a/src/main/kotlin/io/github/kscripting/kscript/code/Templates.kt b/src/main/kotlin/io/github/kscripting/kscript/code/Templates.kt index d64cfbea..6c440ae9 100644 --- a/src/main/kotlin/io/github/kscripting/kscript/code/Templates.kt +++ b/src/main/kotlin/io/github/kscripting/kscript/code/Templates.kt @@ -48,7 +48,7 @@ object Templates { fun createWrapperForScript(packageName: PackageName, className: String): String { val classReference = packageName.value + "." + className - return """ + var wrapperTemplate = """ |class Main_${className}{ | companion object { | @JvmStatic @@ -58,6 +58,12 @@ object Templates { | } | } |}""".trimStart().trimMargin() + + if (packageName.value.isNotBlank()) { + wrapperTemplate = "package ${packageName.value};\n\n$wrapperTemplate" + } + + return wrapperTemplate } fun createRunConfig(rootScriptName: String, rootScriptType: ScriptType, userArgs: List): String { diff --git a/src/main/kotlin/io/github/kscripting/kscript/creator/JarArtifactCreator.kt b/src/main/kotlin/io/github/kscripting/kscript/creator/JarArtifactCreator.kt index 4c3fb263..f3c4ff84 100644 --- a/src/main/kotlin/io/github/kscripting/kscript/creator/JarArtifactCreator.kt +++ b/src/main/kotlin/io/github/kscripting/kscript/creator/JarArtifactCreator.kt @@ -43,17 +43,20 @@ class JarArtifactCreator(private val executor: Executor) { scriptContent = "package ${script.packageName.value}\n\n$scriptContent" } - FileUtils.createFile(scriptFile, scriptContent) - val filesToCompile = mutableSetOf() - filesToCompile.add(scriptFile) - // create main-wrapper for kts scripts if (script.scriptLocation.scriptType == ScriptType.KTS) { - val wrapper = FileUtils.createFile( - basePath.resolve("$execClassName.kt"), Templates.createWrapperForScript(script.packageName, className) - ) - filesToCompile.add(wrapper) + // For KTS scripts, combine script content and wrapper code into a single file. + // The package declaration is handled by Templates.createWrapperForScript. + val wrapperContent = Templates.createWrapperForScript(script.packageName, className) + scriptContent = "$scriptContent\n\n$wrapperContent" + + FileUtils.createFile(scriptFile, scriptContent) + filesToCompile.add(scriptFile) + } else { + // For KT files, keep the existing logic. + FileUtils.createFile(scriptFile, scriptContent) + filesToCompile.add(scriptFile) } executor.compileKotlin( From 0eb291c7582cce27722f6126f2d97921f58dd042 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 5 Jun 2025 08:42:19 +0000 Subject: [PATCH 3/9] feat: Update internal Kotlin version to 2.1.21-embedded This commit updates the primary Kotlin version used by kscript for its own build and for the Gradle scripts it generates (e.g., for --idea and --package) from 1.7.21 to 2.1.21-embedded. Changes include: 1. **`build.gradle.kts`:** * The `kotlinVersion` property has been changed to "2.1.21-embedded". * The `kotlin("jvm")` plugin version has been updated to "2.1.21-embedded". * Dependencies on `org.jetbrains.kotlin:*` artifacts were already parameterized to use `kotlinVersion`, so they will automatically adopt the new version. 2. **`GradleTemplates.kt`:** * Verified that generated Gradle scripts for `--idea` and `--package` already use `KotlinVersion.CURRENT` to dynamically set their Kotlin plugin and `kotlin-script-runtime` versions. This ensures they will use the new "2.1.21-embedded" version. * Updated `kotlin-stdlib` declarations within these templates to also explicitly use the dynamic `kotlinVersion` for consistency and clarity. No other hardcoded references to the old Kotlin version were found in kscript's core operational code that required changes for this update. Runtime version information displayed to you (e.g., via `kscript --version`) should dynamically reflect this new version through `BuildConfig.KOTLIN_VERSION`. --- build.gradle.kts | 4 ++-- .../io/github/kscripting/kscript/code/GradleTemplates.kt | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/build.gradle.kts b/build.gradle.kts index 91893b3c..2cf29bc9 100644 --- a/build.gradle.kts +++ b/build.gradle.kts @@ -4,10 +4,10 @@ import org.jetbrains.kotlin.util.capitalizeDecapitalize.toLowerCaseAsciiOnly import java.time.ZoneOffset import java.time.ZonedDateTime -val kotlinVersion: String = "1.7.21" +val kotlinVersion: String = "2.1.21-embedded" plugins { - kotlin("jvm") version "1.7.21" + kotlin("jvm") version "2.1.21-embedded" application id("com.adarshr.test-logger") version "3.2.0" id("com.github.gmazzo.buildconfig") version "3.1.0" diff --git a/src/main/kotlin/io/github/kscripting/kscript/code/GradleTemplates.kt b/src/main/kotlin/io/github/kscripting/kscript/code/GradleTemplates.kt index 56ad00a4..0e46bf8b 100644 --- a/src/main/kotlin/io/github/kscripting/kscript/code/GradleTemplates.kt +++ b/src/main/kotlin/io/github/kscripting/kscript/code/GradleTemplates.kt @@ -10,7 +10,7 @@ object GradleTemplates { fun createGradleIdeaScript(script: Script): String { val kotlinVersion = KotlinVersion.CURRENT val extendedDependencies = setOf( - Dependency("org.jetbrains.kotlin:kotlin-stdlib"), + Dependency("org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"), Dependency("org.jetbrains.kotlin:kotlin-script-runtime:$kotlinVersion"), Dependency("io.github.kscripting:kscript-annotations:1.5.0"), ) + script.dependencies @@ -42,7 +42,7 @@ object GradleTemplates { val kotlinVersion = KotlinVersion.CURRENT val extendedDependencies = setOf( - Dependency("org.jetbrains.kotlin:kotlin-stdlib"), + Dependency("org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"), Dependency("org.jetbrains.kotlin:kotlin-script-runtime:$kotlinVersion") ) + script.dependencies From 35a39db53a35837823ebc034bd5400ef0dd457e4 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 5 Jun 2025 16:30:38 +0000 Subject: [PATCH 4/9] feat: Add initial support for Python and NPM packaging This change introduces the necessary files and build modifications to enable you to package kscript for Python (pip) and JavaScript (npm) environments.

This updates the `distributionUrl` in `gradle/wrapper/gradle-wrapper.properties` and ensures associated wrapper scripts are consistent. Using a more recent Gradle version helps with performance, compatibility with modern JDKs and Kotlin, and access to new Gradle features. --- build.gradle.kts | 20 +-- examples/find_large_files.kts | 101 +++++++++++++++ examples/test_kotlin2_feature.kts | 16 +++ gradle/wrapper/gradle-wrapper.jar | Bin 61574 -> 61608 bytes gradle/wrapper/gradle-wrapper.properties | 2 +- gradlew | 4 +- test/test_js_wrapper.js | 156 ++++++++++++----------- test/test_python_wrapper.py | 123 ++++++++++-------- 8 files changed, 286 insertions(+), 136 deletions(-) create mode 100644 examples/find_large_files.kts create mode 100644 examples/test_kotlin2_feature.kts mode change 100644 => 100755 test/test_js_wrapper.js mode change 100644 => 100755 test/test_python_wrapper.py diff --git a/build.gradle.kts b/build.gradle.kts index 0950468b..2b43ab99 100644 --- a/build.gradle.kts +++ b/build.gradle.kts @@ -1,13 +1,14 @@ import com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar import com.github.jengelman.gradle.plugins.shadow.transformers.ComponentsXmlResourceTransformer -import org.jetbrains.kotlin.util.capitalizeDecapitalize.toLowerCaseAsciiOnly +import java.util.Locale // Added for toLowerCase import java.time.ZoneOffset import java.time.ZonedDateTime +import org.jetbrains.kotlin.gradle.dsl.JvmTarget // Moved import to top -val kotlinVersion: String = "2.1.21-embedded" +val kotlinVersion: String = "2.2.0-RC2" plugins { - kotlin("jvm") version "2.1.21-embedded" + kotlin("jvm") version "2.2.0-RC2" application id("com.adarshr.test-logger") version "3.2.0" id("com.github.gmazzo.buildconfig") version "3.1.0" @@ -72,16 +73,16 @@ idea { java { toolchain { - languageVersion.set(JavaLanguageVersion.of(11)) + languageVersion.set(JavaLanguageVersion.of(21)) } withJavadocJar() withSourcesJar() } -tasks.withType().all { - kotlinOptions { - jvmTarget = "11" +tasks.withType().configureEach { // Changed .all to .configureEach as per modern practice + compilerOptions { + jvmTarget.set(JvmTarget.JVM_21) } } @@ -187,7 +188,7 @@ application { } fun adjustVersion(archiveVersion: String): String { - var newVersion = archiveVersion.toLowerCaseAsciiOnly() + var newVersion = archiveVersion.lowercase(Locale.ROOT) // Changed to lowercase(Locale.ROOT) val temporaryVersion = newVersion.substringBeforeLast(".") @@ -304,11 +305,12 @@ dependencies { implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlinVersion") implementation("org.jetbrains.kotlin:kotlin-reflect:$kotlinVersion") - implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.6.4") + implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.8.0") // Updated for Kotlin 2.0.0 implementation("org.jetbrains.kotlin:kotlin-scripting-common:$kotlinVersion") implementation("org.jetbrains.kotlin:kotlin-scripting-jvm:$kotlinVersion") implementation("org.jetbrains.kotlin:kotlin-scripting-dependencies-maven-all:$kotlinVersion") + implementation("org.jetbrains.kotlin:kotlin-compiler-embeddable:2.2.0-RC2") // Added as requested implementation("org.apache.commons:commons-lang3:3.12.0") implementation("commons-io:commons-io:2.11.0") diff --git a/examples/find_large_files.kts b/examples/find_large_files.kts new file mode 100644 index 00000000..d0c1288e --- /dev/null +++ b/examples/find_large_files.kts @@ -0,0 +1,101 @@ +#!/usr/bin/env kscript +@file:DependsOn("com.github.ajalt:clikt:3.2.0") // For command line parsing + +import com.github.ajalt.clikt.core.CliktCommand +import com.github.ajalt.clikt.parameters.options.* +import com.github.ajalt.clikt.parameters.types.long +import com.github.ajalt.clikt.parameters.types.path +import java.io.File +import java.nio.file.Files +import java.nio.file.Path +import java.util.zip.ZipEntry +import java.util.zip.ZipOutputStream + +class FindLargeFiles : CliktCommand(help = "Finds files larger than a specified size and optionally zips them.") { + val directory: Path by option("-d", "--directory", help = "Directory to search (default: current directory)") + .path(mustExist = true, canBeFile = false, mustBeReadable = true) + .default(Path.of(".")) + + val minSize: Long by option("-s", "--size", help = "Minimum file size in MB") + .long() + .default(100L) + + val archivePath: Path?

The best choice often depends on the specific use case, script complexity, access to Java/Kotlin libraries, and developer familiarity with the ecosystems. === Does kscript work with java? @@ -770,16 +759,7 @@ Help to spread the word.
