Fix missing license.txt files

[rzo1]

The check-license.txt profile is failing due to LICENCE vs LICENSE ambiquity. In some modules the LICENSE is missing at all.

[reckart]

Any idea why we don't use the maven-rat-plugin exclusively?

[rzo1]

No idea. The profile check-license.txt is inherited from the dkpro-parent (and was failing - I assumed it might be active during a release procedere, so I wanted to fix it)

[reckart]

ok, I'll have a look where this comes from. in other projects, we needed to mix rat and the license checker plugin because of a mix of GPL and ASL code (in DKPro Core) - but this should I think not apply to JWPL.

[rzo1]

There are some classes in JWPL, which are not ASLv2 and have a rather individual license (for example: ListFilter)

[reckart]

If they are ASL-compatible, they should either be recognized by rat or can be excluded from the check and manually recorded in LICENSE / NOTICE files. If they are not compatible, they should probably be removed/replaced.

[rzo1]

They are already properly recorded in the related files and should be compatible :-)

[reckart]

Probably, but me-from-ages-ago might also have missed them while vetting...

[rzo1]

The rat checks are active by default, so other files should be covered as well. I will do an additional check if there are classes not covered by notice files.
