IntelliJ Debugging for Janino

MyTest.java

class MyTest {
    @Test
    public void testX() throws CompileException {
        IScriptEvaluator se = new ScriptEvaluator();
        MyInterface i = (MyInterface) se.createFastEvaluator(""
                        + "System.out.println(\"Hello\");\n"
                        + "String s = \"World\";\n"
                        + "System.out.println(s);\n"
                        + "return true;",
                MyInterface.class, new String[0]);
        // set this to VM options
        // -Dorg.codehaus.janino.source_debugging.enable=true -Dorg.codehaus.janino.source_debugging.dir=./src/main/java
        // this does not work as IntelliJ cannot compile it
        // -Dorg.codehaus.janino.source_debugging.keep=true
        System.out.println("blup = " + i.goForIt());
    }
}

So you were able to debug like that?

Not sure if that worked for me. What really worked for me in the end is creating the source file in the classpath (to make it available to intellij) and start debugger. See here how I create the source: https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/routing/weighting/custom/CustomModelParser.java#L374
