Hallo ihr Lieben,
ich mache gerade mein Software Entwicklungsprojekt und wir haben die Aufgabe das Kartenspiel „Phase 10“ als online Spiel für private Zwecke zu entwickeln. Auch wenn wir erst beim Pflichtenheft sind so will ich für die Implementierungsphase schonmal etwas vorarbeiten.
Nun habe ich mir in Netbeans und auch in Eclipse ein Projekt angelegt den Spielraum erstellt und eine ausführbare jar-Datei erzeugt. Unter Windows klappt auch alles einwandfrei 
aber wenn ich die Datei unter Linux ausführen will heißt es:
„The file ‚/home/m_tschoepe10/Desktop/Phase_10.jar‘ is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run. For more details, read about the executable bit.“
Wenn ich nun die Datei in den Einstellungen ausführbar mache, dann tut sich gar nichts mehr, ich kann so oft drauf klicken wie ich will, es geht einfach nicht. Meine erste Idee, die jar Datei über die Konsole mit:
java -jar „Dateiname.jar“
zu öffnen funktioniert auch nicht, denn dann kommt die Fehlermeldung:
Picked up _JAVA_OPTIONS: -Xms512m -Xmx512m
Exception in thread „main“ java.lang.UnsupportedClassVersionError: phase/pkg10/Phase10 : Unsupported major.minor version 51.0

at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: phase.pkg10.Phase10. Program will exit.
Exit 1
Dann habe ich auch schon versucht, da auf den Uni-Rechnern Eclipse Idigo installiert ist, den kompletten Code zu kopieren und ihn in einem neuen Projekt einzufügen, doch dann kommt die gleiche Fehlermeldung wie oben.
Anbei mal mein Code aber ich bezweifele dass es was hilft
