Zed Java

This extension adds support for the Java language.

Configuration Options

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:
