SWT Resourse Not Properly Disposed - Eclipse Error Log Warning - eclipse

I just installed a couple .jar files to add features to the Eclipse WindowBuilder and for some reason it added a lot of useless toggles under Layout so I deleted them and I have since been getting a warning that my project has errors. I went to the Error Log and got the following message: "Not properly disposed SWT resource". Any help on how to get rid of it?
Thanks!

Scale IDE error when I try to make a new scala project

I installed Scala IDE 4.7.0 and tried to make a new scala project.
But there was "No Applicable Items". (File > New > No Applicable Items)
So, I opened the opening wizard by cmd+N, and chose the scala project.
And, Here is the error code:
Problem Opening Wizard
The selected wizard could not be started.
Plug-in org.scala-ide.sdt.core was unable to load class org.scalaide.ui.internal.wizards.ScalaProjectWizard.
An error occurred while automatically activating bundle org.scala-ide.sdt.core (333).
I did almost everything, e.g. reinstall, remove workspace directory, etc.
But nothing helped out.
Appreciate if someone fix this!

I just installed Eclipse, can't seem to get it to work

I'm very new to programming. But I started out with Eclipse after I couldn't seem to get CodeBlocks to function properly. Now when I installed it, and ran it for the first time (started an empty project and all), an error message was displayed
Building Workspace has encountered a problem. Errors occurred during the build.
I got curious and clicked on details, which showed
Errors occurred during the build.
Errors running builder 'CDT Builder' on project 'Rand1'.
java.lang.NullPointerException.
I got a screenshot of the situation tagged to the post
Here
You can try the following:
run eclipse.exe with the -clean parameter. to do this either navigate to where you installed eclipse and go to properties on eclipse.exe and add -clean in the end of the parameter
run it via command. i recommend you to run via command so that it wont be a permenant thing whenever you start eclipse

Nothing happens when I run my main-containing class under Eclipse?

If I right-click a class, which contains main, then select Debug As Eclipse Application, nothing happens. No error messages displayed, no output in console appears.
I was already meeting this bug, but forgot, what to do with it. Something related with runtime configurations from closed projects, which are hidden, but still have this malicious effect...
Dependency project was closed. Warning was displayed, saying "Error exists in dependency project(s)", listing the project itself (not the dependency project closed, i.e. not correct cause). But this warning is often displayed, when syntax errors exist in elsewhere in the project. If tiny testing class with main, this warning should be ignored. This time there were no syntax error in any project source, but red exclamation mark was present at the project root node in Project Explorer, without any explanations. I regard this as Eclipse bug.

Eclipse Error on Refresh Workspace

I have a little problem with Eclipse, which is driving me insane.
i cannot figure out why, but Eclipse won't refresh any of my projects. it always reports following error:
An internal error occurred during: "Refreshing workspace".
java.lang.String cannot be cast to [Lorg.eclipse.core.resources.FileInfoMatcherDescription;
Well ... google did not helped so far. I tried to close all my projecst and open them again. I also deleted my whole workspace and set up a new Eclipse. It helped for about 2 hours.
has anyone occured the same problem?
Greetings,
Stef
Look at your Eclipse log file (/.metadata/.log) to get the full stack trace and see if that helps you (it probably won't). But then take it and file a bug at eclipse.org, someone will look at it and might have a workaround or something.

Build error in eclipse

I am using eclipse HELIOS. I am getting the following error message whenever I build my project.
Has anyone else experienced such error? Is it a problem of eclipse or the project? It never occured to me before but for this project its happening. It says NullPointerException but that should not pop up such message.
Please help, its driving me nuts. I need to check in my codes but I cant test them due to this building error.
Let me know if more details is reqd.
I found the solution. It was a maven plugin issue. Cleaning up the repository solved it.
First try;
Clean your all project from under project menu and eclipse tries rebuild.
Second try;
Remove your project from eclipse
Delete all files(eclipse project
files like .project) except .java
files and other necessary code files
like .xml
And create a new project from
existing these source codes.
Otherwise you can check your java compiler or eclipse builder path or builder version.
