Can't compile in eclipe - unhandled event loop exception

[Stephan T]

I can't compile my gwt application in Eclipse. Works in Maven outside
Eclipse though. I'm getting an error related to IPixelConverter (see
below for full stacktrace). The version of Eclipse is 3.5.1
(SpringSource Tool Suite2.3.0) and version 2.1.0 of GWT Plugin
installed from the 3.5 update site.

Any ideas why it doesn't work?

Can you drop into your Eclipse installation's plugin directory and tell me the names of all of the plugins in there that start with com.google.gdt.*?

Also, do you see any errors in your Error Log (Window -> Show View -> Error Log)?

Yes, it's the "Unhandled event loop exception" that shows up in the
Error log.

In my plugin folder:
com.google.gdt.eclipse.core_1.4.0.v201010280047.jar
com.google.gdt.eclipse.maven_1.4.0.v201010280047.jar

Sometimes I also get this error in the Error log:

Problems occurred when invoking code from plug-in:
"org.eclipse.core.resources".

[Rajeev Dayal]

This seems really odd - I know that we really only tested GPE against STS 2.5.0 (if you want GPE to work with Roo and Maven project in STS, you need to be using STS 2.5.0), but I still do not understand why you'd be running into problems against an Eclipse 3.5 version of an older incarnation of STS.

Did you have the Google Plugin for Eclipse installed previously? Was this an upgrade?

Yes, I agree, really odd. When using STS 2.5.0 GWT seems to work, but
I get some issues with Maven and dependecies. And my colleagues are
using STS 2.3.0 and everything works for them. But they are using GWT
Plugin 2.0.4. Is it possible to download version 2.0.4 and try? Only
2.1 seems to be available on the update site.

What maven issues are you seeing?

You can install the older version of the plugin in zip format from here:

http://dl.google.com/eclipse/plugin/3.5/zips/com.google.gdt.eclipse.suite.e35.feature_1.3.3.v201006111302.zip

You'll need to uninstall all existing versions of the Google Plugin for Eclipse first. Note that this distro does not include the SDKs, so you'll have to download them manually.

Also, have you tried re-installing the latest version of GPE against a fresh install of STS 2.3.0 and a fresh workspace? I'm wondering if there was possibly some sort of odd problem during installation that corrupted the jars (unlikely, I know).

Hi,

I have the same problem above.

Error An error has occurred. See error log for more details. com/google/gdt/eclipse/platform/shared/ui/IPixelConverter.

You need to Install / reinstall
"Jetty-9 Bundles Composite Repository" - http://download.eclipse.org/jetty/updates/jetty-bundles-9.x
Checklist only: Jetty - Bundles: all the jetty bundles.

[slonik]

Not sure if its the same problem as I get but I can only compile my project in eclipse if I first clear my error log - weird!

[toon...@gmail.com]

Clearing the error log fixes this for me too. GPE 3.4.1

When I click 'Deploy to App Engine ...' I get a dialog and am able to compile prior to deploying.
