[jbosstools-dev] Pull Request against jbosstools-target-platforms repository validated automatically

[Mickael Istria]

Hi all,

With https://issues.jboss.org/browse/JBIDE-22312 , a new CI job [1] now 
validates, mirror and runs p2diff [2] automatically whenever a pull 
request is submitted against the 
jhttps://github.com/jbosstools/jbosstools-target-platforms/ repository. 
This automated validation then report its success or failure on the pull 
request directly, annotating it like Travis CI does (with a green or red 
box depending on success).
It returns a failure if TP validation or mirroring fail. It's most 
likely to happen because of a wrong reference to a p2 repository, a 
missing IU or an incorrect version, or a missing requirement.
It returns a successful build if it managed to validate the PR and 
mirror its content. In such case, there is still need to follow the 
links to the jenkins job have a human look at the p2diff attached to the 
build, and to comment whether p2diff looks fine on the PR. Then, when 
build is successful and p2diff looks good, the PR can be announced to 
the team and considered for a merge.

Notes:
* p2diff report is now generated automatically on regular Maven build 
(even local ones), building the TP with the -Pmultiple2repo profile.
* Triggering validation build is setup as a cron running every 5 
minutes, so it's fine if the build doesn't start immediately after your 
PR creation/update. Just check it again a bit later and in case of 
issue, ping @mickaelistria and/or @nickboldt on this PR
* The validation build takes about 1 hour. There are for sure 
opportunities to speed it up, but as the TP process is slow anyway and 
that this approach is already faster than the previous ones requiring 
local mirror and p2diff, speeding it up isn't high priority at the moment.

Cheers,
