Eclipse wouldn't start, no splash screen, no logs in configuration, nothing...
i had been tweaking my eclipse.ini, and if I took the -vm command out, eclipse would start. But I needed to specify a JDK VM for maven to work right for Confluence plugin development.
finally found this: http://www.eclipsezone.com/eclipse/forums/t99010.html
The -noExit command doesn't seem to work, it must be specified in all lower case.
eclipse -consoleLog -clean -noexit
That finally gave me the message below that it couldn't load 32-bit SWT libraries into a 64-bit java JVM.
So now I am switching to
-vm C:\Progra~2\Java\jdk1.6.0_18\bin\java.exe
in my eclipse.ini
Everything works again.
