5. in the package com.example.demo2 get the error non-project file, only syntax errors are reported

package com.example.demo2; // error: Demo2Application.java is a non-project file, only syntax errors are reported

import org.springframework.boot.SpringApplication;

Additional Informations

The error not ocurrs when you uses maven like a repository script

Windows 上の Spring Initializr Gradle プロジェクトで問題を再現し、com.microsoft.gradle.bs.importer.GradleBuildServerProjectImporter 周辺のプロジェクトインポートパスと、ログに示されている GradleSourceSets の失敗を調査します。Gradle プロジェクトが正常に初期化され、Demo2Application.java が構文エラーだけを報告されるのではなく、プロジェクトファイルとして扱われれば完了です。
