Please help on same.
回答1:
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:
- Strange Maven out of memory error
- Specifying Maven memory parameter without setting MAVEN_OPTS environment variable

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 inC:\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
-Xmxto a higher value if you still get crashes.
