Now the update center for lts contains 2.4 so you should be able to install it.

Please let me know if everything works for you if you encounter any issues.

Hi Magnus,

"stopped working" doesn't mean it shows erros, it simply isn't prioritizing anything anymore at v1.532.1.

I wasn't planning using 1.532.1 yet, but the recommended
wget http://mirrors.jenkins-ci.org/war-stable/latest/jenkins.war
has downloaded this version, so I have trusted this!

Ok, now at update center I can see 2.4, thanks. I'll give it a try.

There must be some problem, because it doesn't upgrades to 2.4.

ok, it upgraded now. (this time, I have updated some other plugins along with priority sorter, and it did the trick)
will report if now works.

Nope,

It still doesn't work on 2.4 @ 1.532.1!

Priority order not respected when asking the jobs to start simultaneously:
2014-01-07 14:54:05.907000
2014-01-07 14:54:05.908000
2014-01-07 14:54:05.908000
2014-01-07 14:54:05.909000
2014-01-07 14:54:05.910000
2014-01-07 14:54:05.911000

Also the jobs were on build queue and started to build without respecting the priority order.

The sorting doesn't happen immediately when a jobs are added, it just happens at intervals (this is how Jenkins works and is nothing that is controlled by the plugin) this means that jobs might get started when added if there's room for them.

If the slaves are all busy you should see the queue getting sorted, I have not tested with 1.531.1 but I have not seen any issues like this in any other version I have tested.

If you look under "Troubleshooting" on the wiki page it describes how to turn on some extra logging to verify what priorities gets assigned to jobs, you can also see when Jobs jumps between states in the queue and when they get removed fro the queue (started).

Could you please turn on this logging and provide logs in this issue that showcases the bad behaviour, this will give me a better starting point to find out what is going on.

Does the new version of priority plugin only allow priority between 1 and 5?
I need at least a 1 to 10! (Old version was 1 to 100...)

You should be able to set any range you like on the main configuration page.

I found an issue that might cause the 2.4 to behave badly.

I will release 2.5 with a fix asap.

Will close this as I haven't heard anything back.

Pls open a new issue if required.
