ラズベリー PI で実行する必要がある JavaFx アプリケーションを開発しています。すべての手順に従って jdk1.8 を Raspberry にインストールし、maven 3.1.1 をダウンロードして、プロジェクトをラズベリーにコピーしました。
私が走るとき
mvn clean package
ビルドは成功しますが、コマンドを実行すると
java -cp app.jar my.main.class
ここで説明されているように ( https://wiki.openjdk.java.net/display/OpenJFX/OpenJFX+on+the+Raspberry+Pi#OpenJFXontheRaspberryPi-RunningaJDKEarlyAccessbuildontheRaspberryPi )
次のエラーが表示されます。
