37% StartingJava Language Server...

The VS-Code‘s Status Bar has been always shows "37% StartingJava Language Server...", when I open a project of VUE(a framework of js+html+css) and edit debug config.
And, it does not automatically create "lunch. Json".

Other, [F1]->[Java: Open JavaLanguage Server log file ], this command can't work, it can't open a log window.

My config:

"java.home": "C:\Program Files\Java\jdk1.8.0_181",
"java.trace.server": "messages"

首先，在编辑调试配置时，在 Vue 项目中复现持续显示的“37% StartingJava Language Server”状态，然后检查输出窗口中报告的日志。还要检查 Java: Open JavaLanguage Server log file 命令。语言服务器完成启动、创建预期的 launch.json，并且日志命令打开其日志窗口，即表示完成。
