Jenkins - java.lang.OutOfMemoryError:PermGen space -

Question

环境:Linux/Windows7,Java 1.6.0.03/37或1.7

我下载了jenkins.war并在使用以下脚本/命令进行初始设置后,我下载了一些插件(10-15)并尝试重新启动Jenkins,它工作正常.然后,我得到了一些插件(总共30-40个),我选择安装或下载+然后+安装,詹金斯没有出现.

即使用startJenkins.sh(仅限Linux).注意:在Windows7上,Jenkins作为Windows服务启动.

#!/bin/bash
export JAVA_HOME=/production/jenkinsAKS/java/jdk1.6.0_03
export JENKINS_HOME=/production/jenkinsAKS
export PATH=${JAVA_HOME}/bin:${PATH}
export JENKINS_HTTP_PORT=9040
export JENKINS_AJP13_PORT=9949
now=`date +%Y%m%d_%H%M%S`

echo  $0 begins ${now}
echo "   java-home=${JAVA_HOME}, jenkins-home=${JENKINS_HOME}, path=${PATH}"
java -jar ${JENKINS_HOME}/lib/jenkins.war -XX:MaxPermSize=4096m --logfile=${JENKINS_HOME}/log/jenkins.log${now} --httpPort=${JENKINS_HTTP_PORT} --ajp13Port=${JENKINS_AJP13_PORT} &

最初我没有使用"-XX:MaxPermSize = 4096m"参数,但是当我看到以下错误消息时,我尝试了各种值,如128/512/1024,2048,4096m等,没有帮助解决错误.

或者有时我看到:

-bash-3.2$

我该如何解决这个问题？当我在Windows台式机上进行相同的练习时,出现了同样的问题.我是否需要使用更少或有限数量的插件？

谢谢

Answer 1

在我的〜/ .bash_profile文件中,我设置了以下3个变量.请注意,此文件中还有其他变量,即JAVA_HOME,ANT_HOME,SONAR_HOME,SONAR_RUNNER_HOME等:

export JAVA_OPTS="-XX:MaxPermSize=512m -Xms512m -Xmx1024m"
export GRADLE_OPTS="-XX:MaxPermSize=512m"
export SONAR_RUNNER_OPTS="-Xmx512m -XX:MaxPermSize=512m"

全部 - 现在工作.

第一个导出行:Jenkins将在没有PermGen错误的情况下运行,第二行将使Gradle在Jenkins调用Gradle脚本时运行(通过另一个包装脚本,例如.sh/etc),第三行使"sonar-runner"命令到工作得很好(否则,我在"初始化Hibernate"之后得到了PermGen的错误...在sonar-runner命令输出期间的行).您在已编译java的工作空间中运行sonar-runner命令,与静态代码分析工具(pmd/checkstyle/findbugs)和其他代码覆盖率报告(jacoco/cobertura)相关的报告.工作区应该有"sonar-project.properties"文件.查找有关此文件的SonarQube帮助页面以及它为项目包含的所有变量.

所有这些选项都记录在这里:http: //docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html 或者如果您使用的是Java 7:http: //docs.oracle.com /javase/7/docs/technotes/tools/windows/java.html
