Network access on the first start. The server runs on Eclipse Temurin of its own Java version, which the extension downloads into ~/.jdks (about 140 MB) when it isn't there yet. You don't need to install a JDK for the server yourself, and it doesn't matter which Java the project uses.
Getting started
Open a folder that contains a Gradle build and open a Java file. The first start downloads the server's runtime and imports the build. Progress shows in the status bar and in notifications you can cancel.
