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，Jenkins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信息时，我尝试了各种值，如128/512 / 1024,2048,4096m等，没有帮助错误。

如何解决此问题？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？

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 - 现在正在工作。
第一个导出行：Jenkins将在没有PermGen错误的情况下运行，当Jenkins调用Gradle脚本（通过另一个包装脚本为ex .sh / etc）时，第二行将使Gradle运行，第三行使＆＃34;声纳浇道＆＃34;命令工作正常（否则，我在＃34;初始化Hibernate＆＃34; ...线在sonar-runner命令输出期间得到PermGen的错误）。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＆＃34; sonar-project.properties＆＃34;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。
这里记录了所有这些选项： 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

如果您使用的是Gradle，则可以通过在Jenkins全局配置中添加GRADLE_OPTS全局环境变量来设置-Xmx或-XX：MaxPermSize。为此，请单击“管理Jenkins”，然后单击“配置系统”。在Global properties部分中，单击Environment Variables复选框，然后添加一个名为GRADLE_OPTS的新环境变量，其值设置如下：
name: GRADLE_OPTS
value: -Xmx1024m -XX:MaxPermSize=1024m
其中1024是指定的内存。您可以根据您的要求进行更改。
Maven需要类似的配置。请参阅以下链接了解更多详情： https://wiki.jenkins-ci.org/display/JENKINS/Builds+failing+with+OutOfMemoryErrors
