I tried to reinstall JavaFX and SceneBuilder but it changed nothing.
Reinstalling Eclipse Software also wasnt helping.

It looks like e(fx)clipse hasn't been updated for 2022-12, which removed some DataBinding APIs.
You can open an issue at https://github.com/eclipse-efx/efxclipse-eclipse/issues, but if you can work up a pull request to fix it, that'll probably move things along far more quickly.

I found a workaround to this problem.
Create a new JavaFX Project
Eclipse Project Creation Wizard Selection Screen
Rename the FXMLDocument to something unique
JavaFX Project Navigator Display
Right-click and copy the .FXML file from the bogus project you just created
Right-click in your real project and paste the .FXML file into the actual project
New .FXML file is in the original JavaFX Project
Delete the bogus JavaFX Project to clean up
Nod sagely and pat yourself on the back

I had the same problem, it was because I was using eclipse 12-2022. Just downgrade it to eclispe 09-2022.

Eclipse/STS starts once - then fails to start again - Mac/Catalina 10.15.7

After trying to install a CVS client into Eclipse/STS (ver 4.7.1) that I use no longer loads. I've re-installed Eclipse/STS a couple of times, but the startup issue persists...I get the exceptions listed below. On intermittent tries after deleting the .metadata/ folder from the workspace, it sometimes loads. But once I close it and try to re-open it never starts on that workspace again.
Things I've tried from other (older) stack-overflow posts :
Reinstalling STS, a couple of time...the CVS client "should" no longer be an issue...It's not even installed on the re-installed version.
Deleting the workspace.xmi file.
Nothing seems to work...And from the stacktrace below, I can't tell what the NullPointerException is referring to. I did verify there is a LegacyIDE.e4xmi file in the location indicated, and I have R/W permissions to it.
Here are the errors in the .log I see.

Figures, as soon as I post the question, I found a solution here :
STS launch issue on Mac
Posted 8 years ago...but it works now. For anyone experiencing this, that org.eclipse.osgi folder is buried in the Mac SpringToolSuite.app contents...which is what the NullPointerException in the stacktrace lists.
I can only surmise that installation of the CVS Client left that in a corrupt state, but I would've thought a Re-install would have gotten rid of it.

basically you see the log file.
I just updated the log file now by renaming the old one, so I get a new one. This is everything in the log file.
The Eclipse .metadata folder contains a lot of information on how Eclipse is used and configured. This could possibly get corrupted somehow causing Eclipse not to start anymore.
To check whether this is the case just open up Eclipse on a complete fresh workspace. Eclipse should then generate a fresh .metadata folder and should at least start up again.
If the startup is successful one can think about importing the projects from the old workspace again and continue from there. Eclipse has to be reconfigured then.

Eclipse fails to open .vue files in Web Page Editor

I would like to open .vue files as regular HTML files in Eclipse. I tried to to right click a .vue file and then Open WithWeb Page Editor. I've also linked .vue in the preferences as a new file association to the Web Page Editor.
Doing exactly the above steps leads to the following error after opening the file. It also throws a NullPointerException:
Failed to create the part's controls
Is this a bug in Eclipse or am I doing something wrong?
My Eclipse version is:
Eclipse Java EE IDE for Web Developers.
Version: Neon.3 Release (4.6.3)
Build id: 20170314-1500
I've seen in the Error Log, that the following message appears, after opening a .vue file in the Web Page Editor:

I found out what the problem is. The Error Log view showed more detailed information about the problem.
The HTML/Web Page Editor requires a file extension to have a valid content type. Because .vue files do not have a predefined content type, the editor just crashes.
As a workaround, you can simply add *.vue to the HTML content type. You can find this setting in Preferences → General → Content Types. Then add *.vue to HTML under Text.
You probably also want to set the default editor for .vue files to the HTML/Web Page Editor. You can do this in Preferences → General → Editors → File Associations
Sorry, that I cannot give out the bounty to anybody =)
You can find the window --> preferences-->editors as the picture shows:
If you do not set up, eclipse can not recognize the suffix of the file name do not know what way to use it

Eclipse: Compare with -> Unhandled loop exception

I downloaded the Last Eclipse Helios Version and set it up to use it with GIT.
I also downloaded and installed the last JAVA JRE8.
Everytime i want to compare a file with the GIT-Index (Right click on the file - Compare with - Git index) I get an eclipse exception and an 'Editor' pops up, with no content.
Is there something wrong with my installed Java or Eclipse?
I also cannot update eclipse using 'Help - Check for updates'...
Cannot complete the install because one or more required items could not be found.

This looks like Eclipse bug 324051 which was closed fixed 4 years ago. It looks like it needs a newer version of Eclipse than Helios.

Eclipse WTP - "No tab group defined for launch configuration type org.eclipse.jst.server.tomcat.core.launchConfigurationType" ...?

When I double-click on my tomcat server on eclipse's "Servers" tab I get taken to the propeties page. This page has only one tab, "Overview" and has a red square as its icon. When I click on the "Open launch configuration" link on the "Overview" tab I get two popup messages:
Exception occurred creating launch configuration tabs
Reason:
No tab group defined for launch configuration type org.eclipse.jst.server.tomcat.core.launchConfigurationType
And:
No tabs defined for launch configuration type Apache Tomcat
Eclipse's "Error Log" tab has:

What can I do to get it to work?
Thanks...
Looks like an installation issue.
Try a new installation of WTP on a clean eclipse (that you can unzip anywhere you want, in order to not mess with your current eclipse installation).
As mentioned in the WTP download page, you can try their update site with the p2 update process.
If you are just getting started with Eclipse or Eclipse Web Tools, you may want to first install from the Galileo update site, as it would have everything you need to get started.
This Web Tools Platform update site does assume you have all the pre-reqs installed.
