java.lang.OutOfMemoryError: Java heap space version: 7.11.0

[Pankraz76]

What version of OpenRewrite are you using?

Pined down specific issue as in other projects this version is running:

// id 'org.openrewrite.rewrite' version '7.11.0' apply false // java.lang.OutOfMemoryError: Java heap space

id 'org.openrewrite.rewrite' version '7.10.0' apply false // failing also but later and with stacktrace

running rewrite in: https://github.com/SonarSource/sonarqube

I am using

• OpenRewrite v1.2.3
• Maven/Gradle plugin v1.2.3
• rewrite-module v1.2.3

How are you running OpenRewrite?

I am using the Maven plugin, and my project is a single module project.

id 'org.openrewrite.rewrite' version '7.10.0' apply false

What is the smallest, simplest way to reproduce the problem?

For more on this, please refer to https://docs.gradle.org/8.9/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Hi, this can happen on larger projects, as already documented:
https://docs.openrewrite.org/reference/faq#im-getting-javalangoutofmemoryerror-java-heap-space-when-running-openrewrite

A way around this is to use the tooling we develop at Moderne, which serializes the LST as opposed to keeping it in memory.
