Eclipse 2022-03 : java.lang.NoClassDefFoundError: org/eclipse/tm4e/ui/utils/ContentTypeHelper Error

Question

I am currently facing error in eclipse while opening yaml as well as xml files.

Error is java.lang.NoClassDefFoundError: org/eclipse/tm4e/ui/utils/ContentTypeHelper.

I installed Eclipse Docker Tooling 5.6.0.20220382138 extension for Dockerfile support via eclipse marketplace.

After installation, I have started seeing above error. So I uninstalled above plugin to see if that will be of any help but still even after uninstallation, error didn't disappear.

I referred this link & installed extension but it is of no help.

Platform : MacOS

Eclipse : 2022-03 (4.23.0)

Does installing TM4E 0.4.5 via the update site [`https://download.eclipse.org/tm4e/releases/0.4.5/`](https://download.eclipse.org/tm4e/releases/0.4.5/) fix your issue? — howlger, Aug 12 '22 at 07:21
Hi @howlger, it's not working even after updating tm4e with 0.4.5 version — Ashish Patil, Aug 12 '22 at 15:41

For this specific issue, I end up re-installing eclipse from eclipse installer as I tried below mentioned things & it still didn't worked:

Installed https://download.eclipse.org/tm4e/releases/0.4.5/ .
Uninstalled above version & installed latest release of tm4e but no success.
Uninstalled tm4e completely which started giving me issues where I was unable to save any changes in java class files. Workspace got freeze after this.
