             Summary: Fix clover to correcty instrument all packages, improve permgen
                 Key: LUCENE-4445

            Reporter: Uwe Schindler

         Attachments: LUCENE-4445.patch

This is a very stupid problem, but after a long time sitting in fornt of the build.xml's I
found it:

1. The biggest problem was: the target "-clover.init" was made in a way that it used the clover.loaded
sysprop to avoid permgen issues. Unfortunatley it not only loaded clover, it also set it up
in this task (setting the java source file folders). If the taskdef was then loaded for the
first time, it had its source folders set up with the module it was called first. The later
coming compilation of another module did not run clover.setup anymore, so no new source folders
were configured. I splitted the IVY-Load+Taskdef from the clover setup.

2. I also improved the code duplication for compile in test-framework. I made it inherit from
common-build, but disable clover instrumentation for test-framework by overriding -clover.setup
target in the test-frameworks (Lucene+Solr).

3. I fixed some permgen issues, so -clover.load is only executed onec. I had to use a trick
to pass the classpath to ivy's cachepath down to the subants, because we don't inherit refs.
The trick was to make the clover.loaded property contain a stringified version of the clover
classpath instead of a simple "true". By that it is automatically passed down using the propertyset.
