Eclipse kann keine neuen Java-Projekte erstellen

Question

Ich betreibe Eclipse 4.5.2 (Mars) auf openSUSE Tumbleweed. Leider kann ich keine Java-Projekte erstellen, da nach dem Klicken auf New-> Java Projects nichts passiert ...

Ich habe bereits Eclipse neu installiert, die Metadaten gelöscht, die Benutzerdaten aus meinem Home-Verzeichnis entfernt. Nichts hat geklappt.

Ich erhalte nur die folgende Fehlermeldung in meinem Protokoll: name = unbehandelte Ereignisschleife Ausnahme; plugin = org.eclipse.ui;

Vielen Dank für Ihre Hilfe!

Answer 1

Sie haben die Desktop-Umgebung, in der Sie Eclipse ausführen, nicht angegeben (KDE, GNOME, LXDE), Eclipse scheint jedoch not to be very compatible with the new GTK3 zu sein.

Ich löste das Problem Eclipse zwingt mit der GTK2 zu arbeiten, können Sie das in Ihrer eclipse.ini Datei die folgenden zwei Zeilen hinzu:

--launcher.GTK_version 
2 

Stellen Sie sicher, fügen Sie die beiden Linien über dem --launcher.appendVmargs Linie.
