errore eclissi esportazione plug-in

Question

Si verifica uno strano errore quando si tenta di esportare un plug-in IMP da eclissi. Quando si utilizza l'indaco eclissi ottengo:

C:\Users\Shachar\workspace jee\.metadata\.plugins\org.eclipse.pde.core\temp\org.eclipse.pde.container.feature\assemble.org.eclipse.pde.container.feature.win32.win32.x86.xml:88: The following error occurred while executing this line:

Lo stesso errore viene visualizzato quando si utilizza Eclipse RCP indaco & versione rap.

Per lo stesso motivo non è possibile creare un sito di aggiornamento per il plug-in.

Questo errore non sembra accadere nella versione jee di eclipse. Mentre l'esportazione riesce, il plugin stesso non funziona (e funziona quando eseguo il progetto).

Answer 1

Ho avuto lo stesso problema. La reinstallazione del plug-in "Eclipse Plug-in Development Environment" ha risolto il problema per me.
