Steps to reproduce:
1. git checkout xwiki-platform-6.4.4 on a Windows OS command line
2. cd xwiki-platform-core/xwiki-platform-search/xwiki-platform-search-lucene/xwiki-platform-lucene-api
3. mvn clean install
There must be some environment issues, but the existing file "src/main/resource/META-INF/components.txt" is not found and the build fails.
On a Linux OS, the above steps produce a successful build.
A workaround should be to use "-Didea.home.path=something" as in "mvn clean install -Didea.home.path=something" but seems to not work for some users.
