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"

まず、デバッグ構成を編集中に Vue プロジェクトで永続的な「37% StartingJava Language Server」ステータスを再現し、その後、報告された出力ウィンドウのログを調べます。Java: Open JavaLanguage Server log file コマンドも確認してください。Language Server の起動が完了し、期待される launch.json が作成され、ログコマンドによってログウィンドウが開けば完了です。
