Impossibile aggiornare Eclipse Luna

Question

mi è sufficiente fare clic Aiuto -> Controlla aggiornamenti e passare attraverso la procedura guidata e ottengo il seguente errore:

An error occurred while collecting items to be installed 
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Sto cercando di aggiornare perché il mio Scala plug-in non è così ho dei fogli di lavoro e ho appena visto che ho un sacco di aggiornamenti di cui ho bisogno di prendermi cura.

Se provando scaricare il plug-in Scala ottengo il seguente errore:

An error occurred while collecting items to be installed 
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Answer 1

Prossimi passi risolto il mio problema:

1. Review ed eliminare i depositi in eccesso. Help > Install New Software > Available Software Sites e deselezionare tutti i siti di aggiornamento per le versioni precedenti di Eclipse. Avevo due repository Spring per la versione 4.3 e 4.4.
2. Cancella directory <eclipse folder>/p2/org.eclipse.equinox.p2.repository/cache.
3. Controlla di nuovo gli aggiornamenti.
