DataHub

:wave: Hello! I am getting
```* What went wrong:
Java heap space```
when trying to build gms locally using `./gradlew :metadata-service:war:build`. Any idea how I can fix this? It happens somewhat randomly and when building frontend service as well

Hey <@U040F8VEDV3>, I think <@U04UKA5L5LK> should be able to help you out here- it could be a bug- what version are you on?

`datahub version`
```DataHub CLI version: 0.8.35.1
Python version: 3.8.13 (default, Jan 16 2023, 20:20:13) 
[Clang 14.0.0 (clang-1400.0.29.202)]```

Could you try increasing the memory for Gradle? <https://stackoverflow.com/questions/63088123/gradle-build-fails-with-out-of-memory-java-heap-space-error>

I uncommented
`#org.gradle.jvmargs=-Xmx2000m`
in gradle.properties and that worked. Thanks so much!

I'm now getting
```ANTLR Tool version 4.5 used for code generation does not match the current runtime version 4.8ANTLR Runtime version 4.5 used for parser compilation does not match the current runtime version 4.8ANTLR Tool version 4.5 used for code generation does not match the current runtime version 4.8ANTLR Runtime version 4.5 used for parser compilation does not match the current runtime version 4.82023/03/20 18:54:37 Command exited with error: exit status 1```
when trying to replace datahub-gms container with local code:
```(cd docker &amp;&amp; COMPOSE_DOCKER_CLI_BUILD=1 DOCKER_BUILDKIT=1 docker-compose -p datahub -f docker-compose-without-neo4j.yml -f docker-compose-without-neo4j.override.yml -f docker-compose.dev.yml up -d --no-deps --force-recreate datahub-gms)```


<@U042KCFV9GX> any chance you'd be able to help here? :pray:

Hey <@U03KVM85874>, I think <@U04UKA5L5LK> might be able to help you here- this is likely a java deps issue, I think some people have dealt with ANTLR issues previously in this slack, so it’s worth a search

In the future it may be good to open up a new thread for visibility, since things can get lost in the shuffle with all the messages!

ack will do! I looked through previous threads but didn't find anything that could help me :confused:

You may want to check your package deps and ensure you aren’t targeting ANTLR 4.8, or try downgrading your system’s ANTLR version

Thanks for the response! How can I downgrade my system's ANTLR version? In my `build.gradle` file I see
`'antlr4Runtime': 'org.antlr:antlr4-runtime:4.7.2',` . I tried changing this manually but it did not like that.

I found this page: <https://www.antlr.org/download.html> depending on your programming language you may be able to specify a different version in the language you're using? e.g. pip install for python?

I did `pip install antlr4-python3-runtime` from my virtual env, but still getting the same error :confused: idk where `the current runtime version 4.8ANTLR` is coming from
