Plugin installation : Unable to read repository #48

Hello,

When installing the plugin from mapstruct website or from eclipse marketplace, I have this error in eclipse:

Unable to read repository at https://mapstruct.org/eclipse/content.xml.
Certificate for <mapstruct.org> doesn't match any of the subject alternative names: [*.github.com, www.github.com, github.io, github.com, *.github.io, githubusercontent.com, *.githubusercontent.com]

Can you look into it ?

I searched a little the website repository and found that there is no content.xml file in the static/eclipse folder, maybe it is related ? (I don't know anything about how to deploy and develop an eclipse plugin).
