Getting Unsupported class file major version 57

You're probably using a Java version that's too new for gradle. Run the following command to check your Java version

java --version

While it may be possible to build and run DataHub using newer versions of Java, we currently only support Java 17 (aka Java 17).

Getting cannot find symbol error for javax.annotation.Generated

Similar to the previous issue, please use Java 17 to build the project. You can install multiple version of Java on a single machine and switch between them using the JAVA_HOME environment variable. See this document for more details.

:metadata-models:generateDataTemplate task fails with java.nio.file.InvalidPathException: Illegal char <:> at index XX or Caused by: java.lang.IllegalArgumentException: 'other' has different root error

This is a known issue when building the project on Windows due a bug in the Pegasus plugin. Please refer to Windows Compatibility.

As we generate quite a few files from the models, it is possible that old generated files may conflict with new model changes. When this happens, a simple ./gradlew clean should reosolve the issue.

Execution failed for task ':metadata-service:restli-servlet-impl:checkRestModel'

This generally means that an incompatible change was introduced to the rest.li API in GMS. You'll need to rebuild the snapshots/IDL by running the following command once

./gradlew :metadata-service:restli-servlet-impl:build -Prest.model.compatibility=ignore

java.io.IOException: No space left on device

This means you're running out of space on your disk to build. Please free up some space or try a different disk.

Build failed for task ./gradlew :datahub-frontend:dist -x yarnTest -x yarnLint

This could mean that you need to update your Yarn version
