Failed to execute goal maven-antrun-plugin - Connection timed out on GitHub Actions

I'm working on a Spring Boot + React/TypeScript app which uses GitHub Actions for CI/CD. I recently added the react-app-rewired package to configure some webpack settings without ejecting our CRA app. Everything builds and runs fine locally (albeit a bit slower), but when pushed to GitHub, the ./mvnw test command fails after 20+ minutes with the following error:

Any help or guidance would be much appreciated.

For the next person who runs into this -- this is basically just an issue with Azure SNAT and Maven interacting. Maven internally pools connections and Azure's SNAT closes them in a way that Java kinda can't see, and Github Actions (since GitHub is owned by Microsoft) runs in Azure.

Anyway -- the fix with current Maven versions is to set a Maven parameter to dial down the TTL on the connection pool. If you need to use an older version, there are some other parameters you can use.

So I added an env var to my workflow:

MAVEN_OPTS: '-Dmaven.wagon.httpconnectionManager.ttlSeconds=120'
