Question

我已经将jenkins安装为windows服务并创建调用ant脚本的作业。 Ant脚本由mxmlc编译器组成，可编译Flex应用程序。虽然编译失败并抛出一个内存异常。我确实调整了ant_opts用于内存分配，但无济于事。但是当我尝试以独立模式运行jenkins时，问题不会发生。

我遇到过类似的问题吗？

在您用完Permgen空间后，请尝试通过调整JVM的参数来增加可用内存。

jenkins.jenkins \ jenkins.xml包含Windows服务的服务设置：这是我们的服务设置的副本。

<service>
  <id>jenkins</id>
  <name>Jenkins</name>
  <description>This service runs Jenkins continuous integration system.</description>
  <env name="JENKINS_HOME" value="%BASE%"/>
  <!--
    if you'd like to run Jenkins with a specific version of Java, specify a full path to java.exe.
    The following value assumes that you have java in your PATH.
  -->
  <executable>java</executable>
  <arguments>-Xrs -Xmx512m -XX:MaxPermSize=512m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "C:\Hudson\.hudson\jenkins.war" --httpPort=80</arguments>
  <logmode>rotate</logmode>
</service>

上周添加了 -XX：MaxPermSize = 512m 参数来解决与您非常相似的问题。

詹金斯作为Windows服务扔掉了内存
