Windows版eclipseでアプリケーションを作成しましたが、これをRaspberry piに移動しました。今は、私はエラーが発生する日食からアプリケーションを実行しようとすると。 /opt/jre/jdk1.8.0_101/bin/java: 1: /opt/jre/jdk1.8.0_101/bin/java: Syntax error: end of file unexpected (expecting ")")Eclipseでプログラムを実行するとJavaの解析エラーが発生する
私はそれが解析エラーであると私は何かにdos2unixを実行する必要があります他の質問を読んで理解する。私はそれを実行するために正確に何ですか？他の質問は主にスクリプト関連です。 .javaファイル、.cssファイル、.fxmlファイルがあります。
以前は.javaファイルを正常に移動して正常に動作しました。
EDIT要求としては、これはあなたのプログラムではなく、あなたのJDKのインストールでエラーではありませんコード
