Lots of build failures for PR-openhab-addons lately

I’ve noticed that a lot of the jenkins PR-builds are failing lately. The most common reason seems to be that the process takes more than 4 hours and is aborted (other times it’s because some other seemingly random issue). The builds that does succeed usually takes 2-3 hours. Is the workload on the server too high, causing the builds to slow down?

Sorry I‘m sure this has been discussed before but why are all addons rebuilt on changes anyway? Wouldn’t it make sense to rebuild everything only if dependencies changed and rebuild only the binding if there was a change in the binding?

@Kai : yes, most of the PR build are now failing because they are aborted after 4 hours.
Do you have any idea what could be done!

Not sure what happened there, but it seems to have fixed it by itself again:

Hi @Kai
It worked relatively well during one (or two) days and since almost one day all PR builds are failing again.
But not for the timeout reason we had during the previous days.
I see two different failures depending on the PR:
One is : ERROR: Maven JVM terminated unexpectedly with exit code 137
The other is: ERROR: Specified HTML directory ‘/home/jenkins/jenkins-agent1/workspace/PR-openHAB-Addons@4/target’ does not exist.
