Hi,

I am getting the following error when I try to install the plugin:

Unable to read repository at https://raw.githubusercontent.com/iloveeclipse/plugins/latest/content.xml.
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I'm using Eclipse 2020-12.

A bit of searching led me to an answer. I used githubusercontent as the alias and the password for the cacert file is changeit.
