GitHub - lnay/java: Extension for Zed to support Java

This extension adds support for the Java language.

If Lombok support is enabled via JDTLS configuration option (settings.java.jdt.ls.lombokSupport.enabled), this extension will download and add Lombok as a javaagent to the JVM arguments for JDTLS.

There are also many more options you can pass directly to the language server, for example:
