org.eclipse.swt.SWTException: "Il widget è eliminato" quando si tenta di aprire AndroidManifest.xml

Question

Sono in esecuzione Windows 8 e utilizzo di Eclipse Kepler Release per creare un'applicazione Android.

Quando clicco sul file AndroidManifest.xml nel mio progetto, ho ricevuto un avviso che mostra il seguente messaggio di errore:

Problems occurred when invoking code from plug-in: "org.eclipse.e4.ui.workbench.swt".

Answer 1

Riavvio l'IDE Eclipse problema risolto.

Answer 2

Avviare Eclipse tramite prompt dei comandi immettendo il comando: eclipse -clean risolto il problema.

Answer 3

È molto meglio chiudere Eclipse e riavviare Eclipse piuttosto che riavviare Eclipse, funzionerà più velocemente.

Answer 4

Eclipse - Kepler/Luna/Marte

per me sono andato a

... \ metadata.plugins \ org.eclipse.e4.workbench // cartella locaiton..

e cancellato tutto il contenuto di

workbench.xmi

e riavviato l'applicazione.

Ha funzionato per me, spero che funzionerà per voi.

Nota: buona ripresa prima di apportare modifiche.
