Small fixes for running tests via launc

I fixed the following stuff
* Don't add *.class files to the source code
* Ignore files under target via .gitignore
* Don't include a source jar
* Fixed pom.xml */pom.xml to run tests 
* Changed *.launched configuration and added initial JUnit assert_equals
Still the following errors present:
* Launch configuration worked for me to run the Juni-tests
* mvn clean install builds but does not run correctly the tests
