Question

I have java maven project which is working fine in my computer but when i upload this project to the ubuntu server and trying to run it on command line using following command its give me error.

Command line code:

mvn exec:java -Dexec.mainClass=SitemapCheck.SitemapAction

Its give me error Like

[WARNING] NOTE: 2 thread(s) did not finish despite being asked to  via interruption. This is not a problem with exec:java, it is a problem with the running code. Although not serious, it should be remedied.
[WARNING] Couldn't destroy threadgroup org.codehaus.mojo.exec.ExecJavaMojo$IsolatedThreadGroup[name=SitemapCheck.SitemapAction,maxpri=10]
java.lang.IllegalThreadStateException

After search on the internet i found one solution but unfortunately its not working

 cleanupDaemonThreads = false

Can anyone please suggest me how can i fixed the error?

Answer 1

I was having the same thread warning issue with that org.codehaus.mojo package that also included a java.lang.IllegalThreadStateException and this command worked for me:

mvn compile exec:java -Dexec.cleanupDaemonThreads=false
