Installation error with eclipse plugins

[tobka777]

Expected behavior

As an Eclipse-User, I want to install and use all plugins that are proposed in ide-settings.

Actual behavior

Installation of some plugins failed i.e. CheckStyle, FreeMarker

Steps to reproduce (bug)

1. Install latest devonfw-ide version
2. devon eclipse

Thanks for filing and fixing the issue. I merged your PR devonfw/ide-settings#19.
As it is a change in the settings it is not directly related to a release.
Projects that forked the settings still have to upstream-merge these changes to get the fix.

@tobka777 before we can close this issue.
For legacy compatibility reasons some plugin URLs are also coded into the eclipse script. It most cases it is not used, but some very old IDE installations do not have a plugins folder in their settings and then that script code comes into play.
Can you create a PR for that as well?

Ok now I also changed some urls for legacy compatibility.
But I have for the plugins in eclipse script problems with:

• soapui: Unable to load repositories. (http://www.soapui.org/eclipse/update/)

Maybe someone has an idea?

was autoclosed by PR, reopening as not all plugins are yet fixed.

The remaining plugin that was still not working is spotbugs.
To complete this story, I just disabled this plugin by default so we have a default installation without errors.

Hint: In order to install the newest spotbugs eclipse plugin without errors, update eclipse to 4.20 or newer.

For background see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=5720346
My summary: Eclipse 2021-03 (aka 4.19) which is installed by devonfw ide 2021.12.001 does not support sha256WithRSAEncryption for Timestamp Signature of signed plugins. This algorithm is now used by GlobalSign TSA - which is one of the few that can be used for timestamping without additional costs. The algorithm support was added in eclipse 4.20.

I have updated to latests eclipse with help of "Check for updates" and could install latest spotbugs plugin 4.5.2.r202112132137-0c8b4d1 with help of "devon ide add-plugin spotbugs"
