Language server stuck

Environment

• Operating System: mac os 10.15.5
• JDK version: How can I check it?
• Visual Studio Code version: 1.47.1
• Java extension version: v0.9.1

Steps To Reproduce

1. git clone sample project
2. run the language server

Sample project : https://github.com/artipie/artipie
Logs

Current Result

The language server process is stuck with:

3d66eddd Importing Maven project(s) [Done]
45e64ec1 Repository registry initialization [Done]
d124c211 Synchronizing projects [Done]
c89fb157 Building [Done]
cad6d4ec Updating indexes [Done]
b0f94fcd Building [Done]
bf96551d Register Watchers [Done]

Expected Result

Language server is able to index java files so I can use navigation, error highlighting features and others.

通过克隆链接的 artipie 示例项目，并在所述的 VS Code 和 Java 扩展环境中运行语言服务器来重现该问题。先从链接的日志和报告的初始化阶段开始，然后验证 Java 文件已建立索引，并且导航和错误高亮能够正常工作，同时服务器不会一直卡住。
