Github actions builder

[avilaton]

Hi, I'm trying to learn about the project by adding a github action to build it. I forked and added a few things to it, would you be able to help me out? It is timing out after a long while, please have a look here https://github.com/avilaton/unitime/runs/4643836519?check_suite_focus=true

Here is one error I received earlier

Error:  /home/runner/work/unitime/unitime/target/src/org/unitime/timetable/util/MemoryCounter.java:[157,30] Unsafe is internal proprietary API and may be removed in a future release

Please try again. We were in the process of updating the Log4j dependency and the Maven build did not work for a few days (the Ant build that is used to make official builds that are available at builds.unitime.org has worked fine).

Thanks Thomas, I replayed it and the error above is gone. It was able to make a lot of progress, it now failed with

Here is the full build log, https://github.com/avilaton/unitime/runs/4715033008?check_suite_focus=true, maybe I'll have time to look into why this could be failing later on but if you have a good hint, that helps.

The error does not seem to be related to UniTime per se:

Could not transfer artifact org.apache.maven:maven-archiver:pom:2.5 from/to central (https://repo.maven.apache.org/maven2): Connection timed out (Read failed)

and the URL for the org.apache.maven:maven-archiver:pom:2.5 artifact seems to work fine: https://repo.maven.apache.org/maven2/org/apache/maven/maven-archiver/2.5/maven-archiver-2.5.pom

In any case, I have updated the maven-jar-plugin version to the latest one (3.2.0) in commit 034bb8f.

[avilaton]

I submitted https://github.com/UniTime/unitime/pull/104, it takes a while for it to build, I wonder if there is anything I can do to make it faster.

[tomas-muller]

I think it would be sufficient to run this on the master branch for now -- that is the UniTime 4.6 development branch. The only other branch where this would make sense would be maint_UniTime45 for the current production version (UniTime 4.5) and perhaps maint_UniTime44 for the previous one (UniTime 4.4). These are the branches for which we do the nightly builds that are available at builds.unitime.org.

Please note that the maint_UniTimeXX will not have the POM file updated with the recent versions like I did not on the master branch.
