Updating <project name> configuration loop; caused by Minecraft Forge gradle files

Minecraft Forge gradle files work in IntelliJ IDEA but not VSCode.

Environment

• Operating System: Windows 10
• JDK version: 1.8.0_131-1-redhat
• Visual Studio Code version: 1.12.2
• Java extension version: 0.5.0

Steps To Reproduce

1. Clone my minecraft mod Souls
2. Open folder with VSCode

The log is this, and then a loop of the last six lines:

As a result of this, the dependencies don't seem to be downloaded because my java files contain lots of missing references.

指定された JDK と拡張機能のバージョンを使い、Windows 上の VS Code で Souls Minecraft mod を開いて問題を再現します。Gradle プロジェクトのインポートと構成の更新に関する Java language server log から始めます。構成ループが停止し、依存関係がダウンロードされ、Java の参照が解決されれば完了です。
