I have an EC2 t2.micro instance with RHEL 8. I have installed Jenkins, created a Maven project, connected git repository. I run the build, it goes through the first few steps....then hangs and does not respond at all, then I have to stop and start the instance again. If I leave it hanging, the build comes back with :
"Maven JVM terminated unexpectedly with exit code 137"
and the build fails. I have T2 Unlimited on the instance so I don't understand why this is happening? I see a lot of people running maven builds multiple times through Jenkins on t2.micro instances...
I run the exact same on t2.small and it runs fine...but my frustration is with the t2.micro...
The solution was to change the EC2 instance type from t2.mirco to t2.small or t2.medium, which have more memory and the maven build runs just fine.
