Running java jar from buildr - not starting
Hi!
In the end of my tasks, I would like to run java's jar.
I wrote the following:
sh "nohup java -jar engine_dev.jar \&> /var/log/engine/dev/startengine.log
\&"
And I see in the logs that the command is being executed:
nohup java -jar engine_dev.jar &> /var/log/engine/dev/startengine.log &
However, the jar does not start.
If I try "java -jar engine_dev.jar " - than the jar starts but in the same
terminal. (jenkins output) so I need the nohup so it will run even if
jenkins logs out of the shell.
If I try the same command with jenkins user (the one that runs buildr) in
the shell - it works just fine.
What could be the problem?

In case someone confronts the same problem:
Jenkins kills the process once finishes working
See here:
https://wiki.jenkins-ci.org/display/JENKINS/ProcessTreeKiller
In order to prevent this behaviour, you need to add the sh BUILD_ID env
e.g.
sh "$BUILD_ID=nohup java -jar my.jar &"

well I had to use nohup otherwise it will close when jenkins finishes its job
So instead I did:
sh "nohup java -jar engine_dev.jar >
/var/log/engine/dev/startengine.log &" (my problem was the extra &
before the >)

Should work... you don't need to escape the ampersand and you shouldn't
need 'nohup'... try:
sh "java -jar engine_dev.jar > /var/log/engine/dev/startengine.log &"
