Error regarding tools.jar during test run

[dimsuz]

I have this test

class SampleTest {
  @Test
  fun testTriggersErrorWhenAppliedToClass() {
    kotlinc()
      .withProcessors(ModelGeneratorProcessor())
      .addKotlin("TestModel.kt", """
        fun main() {
        
        }
      """.trimIndent())
      .compile()
      .failed()
      .withErrorContaining("blah")
  }
}

It fails with

org.junit.ComparisonFailure: null 
Expected :blah
Actual   :error: [kapt] 'com.sun.tools.javac.util.Context' class can't be found ('tools.jar' is absent in the plugin classpath). Kapt won't work.

I am using kotlin 1.3.21, The build.gradle contains:

  testImplementation("org.permissionsdispatcher:kompile-testing:0.1.2")
  testImplementation(files(Jvm.current().toolsJar)) // tried to add this, didn't help

Any hints on what do I do wrong?

I found this comment about adding -Xplugin tools.jar, not sure if it applies here.

For now I managed to solve this by adding

.withClasspath(URLClassLoader.newInstance(arrayOf(File("/usr/lib/jvm/java-8-jdk/lib/tools.jar").toURI().toURL())))

👀 Let us check! Thx for your report.

It may have to do with the java I'm using. Host JDK is 1.8 (to be able to run android studio).
But general kapt tasks in all my projects work without problems, so I suspect it has to do with kotlinc command setup used by this library.

I even tried copying your Compiler class into my project and tweaking it by adding full path to my tools.jar in every way I could (using -Xplugin, using kapt3:apoptions, or adding to -classpath) - nothing worked, same damn error every time :)

The workaround in my previous comment somehow works, but turned out that it breaks on first import statement I use, for example for import com.github.dimsuz.stuff it says "unknown reference: github". I'm not sure why this happens on github, because even inserting this import-line in empty .kt file does not produce this error... That's another question though.

Did you check your jdk path which folder name contain special symbol like '+', I change to '_'. error be fix.
example: folder name is 1.8.0+282 -> 1.8.0_282.
Good luck.
