Building

JDK 8/11 is required for building the project.

Run the mvn spotless:apply to format the project (both Java and Scala).
IDE: Mark paimon-common/target/generated-sources/antlr4 as Sources Root.

If you fail to download paimon-bundle snapshot files during the build, it is likely that your maven settings file does not include a snapshot repository. Uncomment the "repositories" tag in pom.xml file for a workaround.
