I am trying to update installed software and install plugins for a fresh install of eclipse 3.4.2. Whenever I try to update/install I get this error:
"Unexpected error encountered while preparing for the operation. org.eclipse.core.runtime.AssertionFailedException"
Details:

What is causing this problem and how do I fix it?
I fixed my problem by reinstalling eclipse from the archived package. I used the same procedure (to my knowledge) to reinstall as I used the first time, but this time with no errors when trying to update and install features.
p2 was barely able to run in 3.4.x (and was still with quite a few bugs like this one in early 3.5).
Any chance you can try with a 3.5.1 eclipse installation?

There seems to be an annoying bug with GWT 2.6.0. Since The current version in the repository for Eclipse is 2.6.0 I was wondering how I could update to 2.6.1 or 2.7.0 myself.
Is there a way to do that?
The error I am dealing with:
java.lang.NoSuchMethodError: com.google.gwt.dev.cfg.ModuleDefLoader.loadFromClassPath(Lcom/google/gwt/core/ext/TreeLogger;Ljava/lang/String;Z)Lcom/google/gwt/dev/cfg/ModuleDef;

..
which gets thrown as I open a file with the GWT Designer.
You need to download and unzip the SDK manually, then tell Eclipse where to find it: https://developers.google.com/eclipse/docs/using_sdks#adding-sdks
…but GWT Designer is deprecated and won't work with newer versions of GWT. 2.6.1 is the last that works.
I just updated my Eclipse from Galileo to Juno. I created a new workspace and imported a Java Spring MVC based project. When I open it, it begins 'Loading descriptor' and then an error message pops up: An internal error occurred during: "Loading descriptor for mta_pfm.". If I open it using Galileo, there is no error. I tried to disable the validation of XML file in Juno, but it does not work. I have no idea how to fix it now. Please help. Thanks

Some of your projects file may be incompatible with Juno (Juno in it's first release is not very stable, I recommend downloading the official update patches or even better - moving to Kepler which feels more solid).
Anyway, Eclipse can take some runtime arguments as described here: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html
Edit your Juno eclipse.exe shortcut and run "'...\eclipse.exe' -clean" to refresh your project files.
Remember to remove the argument once it's fixed as you have no need to clean the project files every time you start eclipse.
Try to start eclipse in clean mode from the command line
eclipse -clean
Today I programmed myself a Little game, which I compiled into a jar through Eclipse - I made sure its a executable jar, or runnable jar or however you want to call it.
I've sent the jar to a friend of mine, but oddly he's not able to open it.
He's always receiving the "Can not find main class" error, which shouldn't pop up since it works perfectly for me. I've already googled but was not able to find a answer.
If you're interested, you can take a look here, if it works for you:
http://www.file-upload.net/download-3939961/WidzDeluxe.jar.html
Now the question I have is kind of obvious I guess, is the error only for him or do you all have the same problem? What's the cause of it?
If people wish, I also upload the code.
You have compiled class files bundled inside this jar with a different (higher) version of Java. Presumably it was Java 1.7 and the friend of yours is trying to open it with Java 1.6.
Here is the stacktrace I received trying to open your executable jar with Java 1.6.0_21:

Could not find the main class: NewJFrame. Program will exit.
One possible solution that came to my ming would be to set the compliance level to let's say 6.0 in Java Compiler settings in Eclipse. That should to the trick.
I had this same problem, found I was compiling the program for Java 1.7. I ended up updating Java on all my computers that I was running it on and it worked great.
I have installed PMD 3.2.6 plugin on eclipse 3.2 using the steps mentioned in
http://pmd.sourceforge.net/integrations.html#eclipse
However, I get following error if I try to open the PMD views or try to PMD code check.
Note that I did re-start my eclipse after installation.
Also it worked fine when I installed it in Eclipse 3.3. Unfortunately I have to stick to Eclipse 3.2 due to some other constraints.

Anyone faced this issue before?
That's an old version of Eclipse! If PMD isn't supported with that version, you can run PMD at the command line or as an Ant script. Then the plugin integration fails to be a factor.
I have installed openfire 3.7.1 and uploaded Kraken plugin (IM Gateway). It worked fine. But on restarting the system. Its dying every time. I have tried re-installing also.
A part of the error is mentioned below. Can anyone tell what is the issue?
Is Kraken not compatible with openfire 3.7.1?

I solved it.. it seems kraken 1.1.2 is causing this problem with openfire 3.7.1. Tried kraken 1.1.3 beta, and it is working fine
