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?

首先查看 "Contribute a Java Extension" wiki、其中的外部链接，以及 issue 中提到的 vscode-pde 项目。对照 eclipse.jdt.ls 验证文档中描述的流程，并找出缺失或过时的步骤。当新手可以按照指南操作，并使用一个可运行的示例项目创建 Java 扩展时，即表示完成。
