Build: adds signing config to gradle

[paullatzelsperger]

What this PR changes/adds

Adds publication config, such as project name, description, etc. plus the OSSHR Maven repository as well as signing configs to the build file.

Why it does that

Required by OSSRH/MavenCentral

Todo

• Should the signing stuff get moved into its own plugin?

Further notes:

• ./gradlew publishToMavenLocal now takes very long (>5min on an Intel i9), and it seems not to be multi-thread-able. It's probably the signing that actually takes so long.

@mspiekermann are you cool with adding you as "the man"?

[mspiekermann]

Sure, if this is a mandatory field, I don't mind if you add my name and mail. Maybe it would be a good idea to name a second? Had a quick look on other projects and mostly two developers are mentioned.

Reviewed changes

• files needing correction for doc generation have been addressed and match up with the records I have
• pulling branch and confirming that the execution runs as expected generating necessary artifacts

[paullatzelsperger]

@jimmarino @juliapampus @MoritzKeppler @mspiekermann how do we proceed with this? should we merge it and try to get it to build on JIPP?

[chrislomonico]

Completed confirmation that all necessary artifacts are being signed with local build and against a Jenkins local instance. Per previous comments the rest of the files that needed to be modified (contained formatting errors) align with the list of those I found.
