Solution
I have the same problem with each XML files in my Eclipse. In my case this is caused because I use an enterprise proxy and an "older" version of Eclipse (2019). That put a lot of "red cross errors" on all of my projects folders but that will not avoid it to work. I think you can fix it by configuring "Network Connections" in a newer version.
