java.lang.OutOfMemoryError: Java heap space on Maven build step with testcontainers

[Jelena Bunčić]

I have error java.lang.OutOfMemoryError: Java heap space, when step maven build run. I have testcontainer and use postgres image. Some tests pass but in one moment error is java.lang.OutOfMemoryError: Java heap space.
I try to set in definitions

services:
  docker-with-large-memory:
    memory: 5120
    type: docker

and then in my step for build maven set

size: 2x
services:
- docker-with-large-memory

but it doesn't work. Can anybody now what i need to do?

You will need to either increase the maximum size of the heap, or look into your build process to see what is consuming so much memory.
