Hi,
I just added and activated the apache-rat-plugin to the maven build. This checks if all source files have the required Apache license headers included and breaks the build if they are missing. This did bring up a hand full of issues, but I sorted them out and all seems to be ok now. One thing I should mention about the patch files. They are generated and didn't contain the license header. I added this and all is working nicely. But I think the code to create the patch files should also be adjusted to add the header or the next update of the patches will break the build. Chris
