I don't think so, but you can checkout the initial commit of some newly-added database support (e.g. the nearest one I can find is 3f29b04, for oceanbase) to know how to get started, and adapt them to your own database.

Hello,
I'm ready to run sqlancer in idea, but I find errors. Can you give me some guidance? Thank you very much

java: Internal compiler error: java.lang.Exception: java.lang.NoClassDefFoundError: com/google/common/collect/AbstractMapBasedMultimap$KeySet at org.eclipse.jdt.internal.compiler.apt.dispatch.RoundDispatcher.handleProcessor(RoundDispatcher.java:172)

Maven project should be supported without additional configuration in IDEA. If you have issue running, you can try command line first, like https://github.com/sqlancer/sqlancer#getting-started. You can also join the Slack channel for use and implement -wise questions: https://github.com/sqlancer/sqlancer#community

There is no problem running under Linux

Seems related to IDEA configs:
