Eclipse plugins can not be installed on Ubuntu

[jan-vcapgemini]

Expected behavior

As a devonfw-ide Eclipse user, I expect devonfw to install my Eclipse in a working condition.

Actual behavior

Devonfw-ide manages to download the latest version of Eclipse but fails to install the plugins provided by our settings.
After all plugins threw an error message, Eclipse can not be started.
