Bug#787552: [eclipse-wtp][FTBFS][LICENSE Problem] Multiple distribution problem

[bastien ROUCARIÈS]

Package: eclipse-wtp
Severity: serious
x-Debbugs-CC: ftpmaster at debian.org

According to your todo:
>Part of source files in org.eclipse.wst.sse.core should be regenerated from 
>JFlex grammar files in directory DevTimeSupport, but they require JFlex 1.2.2 
>for correct transformation (Debian has newer version). Migration to newer 
>JFlex seems not going to happen very soon in upstream[1]
>
>There are still some binary resource files in org.eclipse.wst.jsdt.core 
>(part1.rsc, start1.rsc etc.), but I could not trace their origin and if and 
>how they can be regenerated. Seems the same files are present in jdt parser 
>and also other eclipse plugins. Should be regenerated when possible.

According to Debian Free Software Guidelines [1] (DFSG) #2:
"The program must include source code, and must allow distribution 
 in source code as well as compiled form.".

This could also constitute a license violation for some copyleft licenses such 
as the GNU GPL.

In order to solve this problem, you could:
1. repack the origin tarball adding the missing source to it.
2  add the source files to "debian/missing-sources" directory

Both way satisfies the requirement that we ship the source. Second option
might be preferable due to the following reasons [2]:
 - Upstream can do it too and you could even supply a patch to them, thus full 
filling our social contract [3], see particularly §2.
 - If source and non-source are in different locations, ftpmasters may
   miss the source and (needlessly) reject the package.
 - The source isn't duplicated in every .diff.gz/.debian.tar.* (though
   this only really matters for larger sources).

You could also ask debian-qa at lists.debian.org or #debian-qa for more
guidance.
