Pipeline shuts down prematurely without any log on maven

[thiagoalg]

Hi guys!

I'm trying out the Bitbucket Pipeline to build our project after every commit and I ran into a problem that I cant figure out what it might be.

After running a maven clean install, at a certain point of the process, maven log stops and build fails. On maven, no error is displayed that would indicate a problem (even with Debug mode on). My guess is something related to the environment resources or some limitation that I could not figure out.

The only thing i saw on the log that was weird was this:

Our application is pretty robust and uses a lot of memory to run tests, and thats exactly when the build fails with no log. 2048 memory does not seem to be enough. Wondering if theres a possibility to have more.

Sorry for this ticket being so vague. I just have no other clues of what can be causing this.

Thanks for the help!

Hey Thiago, feel free to contact support.atlassian.com to get specific help if you don't get your answer here.

What you describe does sound like the memory limits of the system are being hit. You could attempt to replicate this behaviour locally with "docker run -ti -v $(pwd):/opt/app w /opt/app  –memory=2048 maven:3.3.3jdk7 /bin/bash"

I'll see if I can find the current open enhancement tickets for more memory.

Thanks for the help sebastian! I will try to run this on a local docker instance and see if i get the same issue.

Hi Thiago,

It sounds like your build is hitting our resource limits (currently 2GB memory, 2 hour execution, or CPU limits, see https://confluence.atlassian.com/pages/viewpage.action?pageId=827106051).

Unfortunately these limits aren't configurable at the moment but most users can build within these limits by reducing the resource requirements of their builds. This usually involves reducing the max heap size and test fork settings in your build tool. This page describes the test fork options for the maven surefire plugin: http://maven.apache.org/surefire/maven-surefire-plugin/examples/fork-options-and-parallel-execution.html
