liferay - Dont run job when it is allready running -

-

I have a job set in liefair, for example, if this job is going on every 5 minutes and fulfilling it It requires more than 5 minutes

What I have seen is that the job will start right now, this can cause problems for me.

Is it not possible in any way a job, when it is going on completely?

* Use of cramps 6.0.6

thanks

Try LockLocalServiceUtil and its methods lock () , unlock () and isLocked () . Something like this: 

  Try {if (LockLocalServiceUtil.isLocked ()) {return; } LockLocalServiceUtil.lock (); // your work} finally {LockLocalServiceUtil.unlock (); }   
 The lock is stored in the database, so there will be no problem in the cluster environment.

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
