Hello:
I’m having a problem with updating my eclipse software, and can’t seem to locate any information in the FAQs or elsewhere on the forums.
My Environment
————————————————————————–
Windows XP
Eclipse 3.0.0 (Fresh install for MyEclipse)
Serveral Plugins installed including P4-WSAD
8 PDE plugins
MyEclipse v3.8.4
JDK v1.4.2-b28 for both Eclipse and AppServer (Oracle OC4J)The Problem
—————————————————————————
Any attempt to use Help->Software Updates functions results in a popup error saying “NullPointerException.” Contents of the Eclipse logfile are as follows:!ENTRY org.eclipse.update.ui 4 0 Mar 09, 2005 11:12:29.787
!MESSAGE java.lang.NullPointerException
!STACK 0
java.lang.NullPointerException

at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:101)Any help is greatly appreciated since I know I’m behind by at least on patch to the Eclipse core.
Try and shut down MyEclipse, edit your shortcut that you use to launch it and add the -clean command line argument then restart. See if that helps.
That actually caused my “MyEclipse” installation to no longer be found, and the entire IDE stopped working properly. I’ve uninstalled both MyEclipse and eclipse, and am trying a fresh install. That sucked.
As nabil correctly pointed out, -clean merely erases the plugin cache, which makes Eclipse rebuild it on the next startup… if -clean barfed on your install then there was something seriously wrong with the install (not your fault, likely just some corrupt plugin state or something wacky). Either way I think you did the right choice with the fresh install to remove any other potentials that could popup.
