4. Fail.
5. Repeat continuously for days/weeks.

Current Result

It is impossible to "Contribute a Java Extension"

Expected Result

A simple, easy to follow guide on how to get started creating a Java extension. A working example project would be preferred.

Additional Information

While this may have sounded harsh it is a result of my frustration. I find it absurd that a requirement of creating an extension to a plugin for your favorite lightweight IDE is the installation of a resource heavy IDE which the user may loathe using.

@testforstephen if it is possible to do, would you mind creating a sample project which leverages your vscode-pde to create an extension targeting the eclipse.jdt.ls currently in use by vscode-java?

Start by reviewing the "Contribute a Java Extension" wiki, its external links, and the vscode-pde project mentioned in the issue. Verify the documented process against eclipse.jdt.ls and identify the missing or outdated steps. Done means a newcomer can follow the guide and use a working example project to create a Java extension.
