Installing under 3.5

[gregjohnson1024]

Hi folks,
I used the 3.5 installation site (http://download.instantiations.com/D2WB ... ate/E-3.5/) and installed all the items (they all said mandatory) but cannot (re)start Eclipse - with a referred to error log that looks like:

!SESSION Mon Jul 13 15:55:18 EDT 2009 ------------------------------------------
!ENTRY org.eclipse.equinox.launcher 4 0 2009-07-13 15:55:18.789

Does anyone have any ideas what is going on? Did I just hose my 3.5 installation?

Cheers,
greg

Hmm, should have mentioned this was under OSX. I saw a mention that Cocoa was not supported - is that still true?

Cocoa support was added as of our 7.1 release (in conjunction with Eclipse 3.5).

As to the exception you posted, I have never seen that one before.

Are you using a brand new Eclipse 3.5 installation? Which specific distribution?

A ClassNotFoundException referencing an Eclipse class is highly unusual.

I would be tempted to start over with a clean Eclipse 3.5 install.

I have now done a clean install of Eclipse (RCP package from eclipse.org) for Mac Cocoa. It runs fine. I give it the update site of http://download.instantiations.com/D2RC ... ate/E-3.5/

and restart immediately afterwards. The restart fails with this message:

I am able to restore Eclipse to working health by taking the original configuration/config.ini file and overwriting the one that has been modified during the SWTDesigner install. The differences are:

% diff config.ini.orig config.ini.postswtdesigner

Does this contain any clues?

Not that I can see. Eclipse updates the config.ini file, not SWT Designer.

I am also unfamiliar with the contents or format of that file, so those diffs don't mean much in any case. It just looks like SWT Designer is installed.

I have never seen a ClassNotFoundException referencing EclipseStarter before (never even heard of that class before), but it is a base Eclipse class so it does not make any sense that it can't be found.

What version of OSX are you running and on what type of machine?

[gregjohnson1024]

I wonder if this is a bigger problem. It now appears to affect me when installing Subclipse. In case anyone ever comes across this post, the problem was resolved on my machine by reverting the line:

osgi.framework=file\:/Applications/Addons/eclipse35B/Eclipse.app/Contents/MacOS/plugins/org.eclipse.osgi_3.5.0.v20090520.jar
to
osgi.framework=file\:plugins/org.eclipse.osgi_3.5.0.v20090520.jar

Though in fact, I think the problem is that Eclipse used a hardcoded reference to it's bundle name (Eclipse.app) which in my case is invalid - it had been renamed to Eclipse35.app. Off to bugs.eclipse.org with me!

Strange but true. Eric C, thanks for the commentary. No fault of SWTDesigner apparently!

Whew!
