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:
Example taken from JDTLS's configuration options wiki page.
You can see all the options JDTLS accepts here.
