Zed Java

This extension adds support for the Java language.

Configuration

Settings

You can optionally configure the class path that JDTLS uses in your Zed settings.

Below is a configuration example for this extension:

{
  "lsp": {
    "jdtls": {
      "settings": {
        "classpath": "/path/to/classes.jar:/path/to/more/classes/"
      }
    }
  }
}

Initialization Options

If Lombok support is enabled via JDTLS initialization option (initialization_options.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:
