I don't have the full context of your problem, but maybe increasing the allocated memory when you run the Maven build could help:

mvn clean install -DargLine="-Xmx1536m"

Here are some other examples on how to increase the allocated memory:

Jenkins Windows setup comes with a 32-bit Java Runtime by default. Swapping that out with a 64-bit version and increasing the available memory through the -Xmx parameter did the trick for me. Jenkins machine is running stable for some months now.

How to replace default 32-bit Java Runtime with a 64-bit one:

  • Download OpenJDK 8 JRE for Windows x64
    • ⚠️ Note: Newer runtime may cause issues with some plugins. See Java requirements.
  • Extract ZIP file to some folder, typically C:\Program Files\Java\JRE8
  • Edit "jenkins.xml" to point to JRE8 (typically located in C:\Program Files (x86)\Jenkins):
    • <executable>C:\Program Files\Java\JRE8\bin\java</executable>

How to increase available memory for Jenkins:

  • Edit "jenkins.xml" to increase argument of parameter -Xmx (typically located in C:\Program Files (x86)\Jenkins):
    • <arguments>-Xrs -Xmx1536m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8080 --webroot="%BASE%\war"</arguments>
    • This is just a sample of my configuration. In my experience 1,5 GiB memory works quite well. You may set -Xmx to a higher value if you still get crashes.
