Where to find the source code of grooid.jar

[alexyuyxj]

i am trying to fix this issue(GroovyClassLoader broken in Android API 24), can you tell me how to find the source code of grooid.jar

I think may be I have fixed this bug, and here is my solution: override method "createClass" of class "ClassCollector" in "GrooidClassLoader", then catch its "byte[] code" argument. This is the compiled groovy class which we are going to transform into dex file.

My english is bad, so I am going to paste some java codes, which may be much clearer.

firstly, groovy class:

class Test {
    static main(args) {
        println 111111111
    }
}

secondly, override ClassCollector.createClass:

return new ClassCollector(loader, unit, su) {
    protected Class createClass(byte[] code, ClassNode classNode) {
        try {
            FileOutputStream fos = new FileOutputStream("/sdcard/" + classNode + ".class");
            fos.write(code);
            fos.flush();
            fos.close();
        } catch (Throwable t) {}
        return super.createClass(code, classNode);
    }
    …………
};

and then reload the byte array into dex:

private HashMap<String, byte[]> readAssets(String dir) throws Throwable {
    HashMap<String, byte[]> classes = new HashMap<String, byte[]>();
    String path = "Test.class";
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    InputStream is = getAssets().open(path);
    byte[] buf = new byte[1024];
    int len = is.read(buf);
    while (len > 0) {
        baos.write(buf, 0, len);
        len = is.read(buf);
    }
    is.close();
    baos.close();
    classes.put(path, baos.toByteArray());
}

ClassDefItem item = CfTranslator.translate(classPath, classBytes, cfOptions, dexOptions);
dex.add(item);

finally, call "Test.main()" by reflection:

try {
    Class<?> Test = Class.forName("Test");
    Method mth = Test.getMethod("main", String[].class);
    mth.invoke(null, Array.newInstance(String.class, 0));
} catch (Throwable t) {
    t.printStackTrace();
}

Are you sure this method really works? I have tested that the createClass method(in the ClassCollector) was never called if it crashed with this. BUG! exception in phase 'semantic analysis' in source unit 'script14710549832242032452851.groovy' throw with null exception
