maven - Java.lang.OutOfMemoryError: Java heap space when loading jobs on Jenkins -


i trying setup ci environment using jenkins maven project. configured , compiles, when jenkins restarted, job not shown in gui. taking @ log, get:

severe: failed loading job test java.lang.outofmemoryerror: java heap space @ java.util.arrays.copyof(arrays.java:2219) @ java.util.vector.grow(vector.java:262) @ java.util.vector.ensurecapacityhelper(vector.java:242) @ java.util.vector.addelement(vector.java:616) @ java.util.stack.push(stack.java:67) @ hudson.maven.mavenmoduleset.onload(mavenmoduleset.java:810) @ hudson.model.items.load(items.java:279) @ jenkins.model.jenkins$18.run(jenkins.java:2634) @ org.jvnet.hudson.reactor.taskgraphbuilder$taskimpl.run(taskgraphbuilder.java:169) @ org.jvnet.hudson.reactor.reactor.runtask(reactor.java:282) @ jenkins.model.jenkins$7.runtask(jenkins.java:885) @ org.jvnet.hudson.reactor.reactor$2.run(reactor.java:210) @ org.jvnet.hudson.reactor.reactor$node.run(reactor.java:117) @ java.util.concurrent.threadpoolexecutor.runworker(threadpoolexecutor.java:1145) @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:615) @ java.lang.thread.run(thread.java:745)

i trying troubleshoot , noticed happens after run build (if configure , restart jenkins, shows up. if run build , restart again, disappears)

i searched problem , got many answers

1- going manage > configuration > maven project config , adding -xmx1048m -xx:maxpermsize=512m maven_opts

2- adding java_opts in manage > configuration > environment variables

3- going /etc/sysconfig/jenkins , changing jenkins_java_options

4- shuold able change jenkins_home/jenkins.xml, doesn't exist

how can solve this?

thanks

i've added line:

 -xms1024m -xmx2048m -xx:newsize=256m -xx:maxnewsize=356m -xx:permsize=1024m -xx:maxpermsize=1024m

to /etc/sysconfig/jenkins file , using jps -mlv can check being applied. though, issue stills happens. happens when loading job, not running it, think maven's heap not problem here...

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
