I am interested in parsing a Kotlin program into its PSI elements. After some readings, I first set up a project by creating an environment and convert Kotlin source as a string to a KtFile
. However, it seems calling KotlinCoreEnvironment.createForProduction(parentDisposable: Disposable, configuration: CompilerConfiguration, configFiles: EnvironmentConfigFiles)
seems to be triggering this java.lang.IllegalStateException
error.
After googling, I tried changing JDK from 11 to 8, but it didn't resolve the issue. Any advice on how to resolve this problem?
Below is the error message:

Just to be clear, when I am calling the KotlinCoreEnvironment.createForProduction
in creating a KtFile
, I believe I'm importing all the right ones... Please correct me if I am mistaken anywhere and see the code snippet below (the line marked with >>
).
import org.jetbrains.kotlin.com.intellij.openapi.fileTypes.FileType
import org.jetbrains.kotlin.com.intellij.openapi.Disposable
import org.jetbrains.kotlin.com.intellij.openapi.util.Disposer
import org.jetbrains.kotlin.com.intellij.psi.PsiManager
import org.jetbrains.kotlin.com.intellij.testFramework.LightVirtualFile
import org.jetbrains.kotlin.config.CompilerConfiguration
import org.jetbrains.kotlin.cli.jvm.compiler.EnvironmentConfigFiles
import org.jetbrains.kotlin.cli.jvm.compiler.KotlinCoreEnvironment
import org.jetbrains.kotlin.idea.KotlinFileType
import org.jetbrains.kotlin.psi.KtFile
...
fun createKtFile(codeString: String, fileName: String): KtFile {
val disposable: Disposable = Disposer.newDisposable()
val config = CompilerConfiguration()
val configFiles: EnvironmentConfigFiles = EnvironmentConfigFiles.JVM_CONFIG_FILES
try {
val proj =
>> KotlinCoreEnvironment.createForProduction(disposable, config, configFiles).project
val fileType: FileType = KotlinFileType.INSTANCE as FileType
val file = LightVirtualFile(fileName, fileType, codeString)
return PsiManager.getInstance(proj).findFile(file) as KtFile
} finally {
disposable.dispose()
}
}
By the way, the suggestion I tried such as using the latest version of org.jetbrains.itellij
didn't really work because with the latest version, I failed to build the project.
As suggested in the comment by @Alexey Belkov, I had to add a message collector instance to the compiler configuration.
Below code works now.
fun createKtFile(codeString: String, fileName: String): KtFile {
val disposable: Disposable = Disposer.newDisposable()
val config = CompilerConfiguration()
config.put(CLIConfigurationKeys.MESSAGE_COLLECTOR_KEY, PrintingMessageCollector(System.err, MessageRenderer.PLAIN_FULL_PATHS, false))
val configFiles: EnvironmentConfigFiles = EnvironmentConfigFiles.JVM_CONFIG_FILES
try {
val env =
KotlinCoreEnvironment.createForProduction(disposable, config, configFiles)
val fileType: FileType = KotlinFileType.INSTANCE as FileType
val file = LightVirtualFile(fileName, fileType, codeString.trimIndent())
val res: KtFile = PsiManager.getInstance(env.project).findFile(file) as KtFile
return res
} finally {
disposable.dispose()
}
}
