gradle wrapperコマンドを使用してgradlewファイルを作成するときに問題が発生しました。私のセットアップは簡単です：使用のUbuntu 14.04 + Javaの8（OpenJDKのバージョン "1.8.0_91"）+ Gradleの3.0Java 8でSpringブートアプリケーションでgradleラッパーが失敗する、Gradle 3：cacertsが見つかりません
チュートリアル：
- https://spring.io/guides/gs/spring-boot/#scratch
- https://docs.gradle.org/current/userguide/gradle_wrapper.html
の好奇心の事この問題は、gradle wrapperが失敗するのは、cacertsファイルまたはディレクトリが見当たりませんからですが、そうではありません（下記の「check cacertsファイル/ディレクトリ」を参照してください）。しかし、これが問題であれば教えてください。実際のファイル/ディレクトリではなくリンクです。私は他の問題があるかどうかわからないcacertsのエラーは、カスケードエラーの終わりにあるようだが、これをデバッグするための任意の助けに感謝します。
関連ファイルと出力を以下に示します。
乾杯

ありがとうTobias。私はこのバグについていくつか読んで明日これを試してみます： $ sudo dpkg --purge --force-depends ca-certificates-java に続いて $ sudo apt-get install ca-certificates-java – AHL
