Code Coverage calculating via maven build returns 0% coverage because it's using source code and binary plugins installed from update site.

When these are built locally prior to build calculating code coverage it returns correct results.

Unfortunately sometimes maven build used plugins installed from update site instead of those which are locally build.

We need to find way how to fix this.

It's already reported here https://bugs.eclipse.org/bugs/show_bug.cgi?id=352560
