Maven multiproject with jsweet (java to Javascript). communication between modules within project

Question

Edit: Enter compiler Failure, thats the error code.

First things first: Sorry for the massive WallOfCode, tried to give all informations i have.

Hey, this is my first time here. I will try to descripe my problem as best i can do. i create a maven multi project, with 2 modules. TestA and TestB within TestA is my main for later JS Convertion. within TestB are 2 classes, one for a method:

public String foo (String s, String t) {
    Exchange ex = new Exchange( s.trim(), t.trim() );
}

and one for a cache but this we can forget at this moment.

if TestA generate a object from foo (TestB) and use it for a simple sout i got a error. if TestA generate a object from a method within TestA and use it for a simple sout it worked.

i cant get contact to the TestB Class , a second Module, i guess.

my convertion from java to javascript code works fine for using methode within my TestA class

Hopefully that someone can help me out, struggle few days with it.

here some code:
