ClassNotFoundException ScriptingCompilerConfigurationComponentRegistrar

[Gabi Moreno]

Hi! 🙂

Not sure if this is actually an issue with the library or if I have a version conflict among dependencies in my project.

I see this error when I run my tests:

Exception on loading scripting plugin: java.lang.ClassNotFoundException: org.jetbrains.kotlin.scripting.compiler.plugin.ScriptingCompilerConfigurationComponentRegistrar

I have this configuration:

[versions]
agp = "8.1.1"
kotlin = '1.8.20'
kotlinpoet = "1.14.2"
ksp = "1.8.20-1.0.11"
kotlin-compile-testing = "1.5.0"

[libraries]
agp = { module = "com.android.tools.build:gradle", version.ref = "agp" }
kotlin-gradle-plugin = { module = "org.jetbrains.kotlin:kotlin-gradle-plugin", version.ref = "kotlin" }
kotlinpoet = { group = "com.squareup", name = "kotlinpoet", version.ref = "kotlinpoet" }
kotlinpoet-ksp = { group = "com.squareup", name = "kotlinpoet-ksp", version.ref = "kotlinpoet" }
ksp = { module = "com.google.devtools.ksp:symbol-processing", version.ref = "ksp" }
ksp-api = { module = "com.google.devtools.ksp:symbol-processing-api", version.ref = "ksp" }
ksp-gradlePlugin = { module = "com.google.devtools.ksp:symbol-processing-gradle-plugin", version.ref = "ksp" }
compiletest = { group = "com.github.tschuchortdev", name = "kotlin-compile-testing", version.ref = "kotlin-compile-testing" }
compiletest-ksp = { group = "com.github.tschuchortdev", name = "kotlin-compile-testing-ksp", version.ref = "kotlin-compile-testing" }

[plugins]
android-application = { id = "com.android.application", version.ref = "agp" }
android-library = { id = "com.android.library", version.ref = "agp" }
ksp = { id = "com.google.devtools.ksp", version.ref = "ksp"}

Do you now what can be the source of the error?

Could it be because the KSP version is not compatible?

ext.ksp_version = '1.8.0-1.0.8'

Thank you so much for the help! 😊

I think it could be because the Kotlin version from the library (1.8.0) is different from the one I am currently using in my project (1.8.20). It seems it works with KAPT, but not with KSP.

I tried updating to 1.9.0 using this fork and it worked. To get the generated files I did this that I saw among the comments in the issues:

    private val JvmCompilationResult.kspGeneratedSources: List<File>
        get() {
            val kspWorkingDir = outputDirectory.parentFile.resolve(KSP_GENERATED_FOLDER)
            val kspGeneratedDir = kspWorkingDir.resolve(SOURCES_GENERATED_FOLDER)
            val kotlinGeneratedDir = kspGeneratedDir.resolve(KOTLIN_GENERATED_FOLDER)
            return kotlinGeneratedDir.listFilesRecursively()
        }

    private fun File.listFilesRecursively(): List<File> {
        return listFiles()?.flatMap { file ->
            if (file.isDirectory) {
                file.listFilesRecursively()
            } else {
                listOf(file)
            }
        } ?: emptyList()
    }

// ...

private const val KSP_GENERATED_FOLDER = "ksp"
private const val SOURCES_GENERATED_FOLDER = "sources"
private const val KOTLIN_GENERATED_FOLDER = "kotlin"
