I'm having a really strange issue. I'm a few days into work on a new android studio project with LibGDX, as a relative beginner to android/android studio/java/LibGDX, and I have just been trying to learn using VCS with GitHub so that I could make changes without worrying about damages.

However when I attempt to commit my project, my commit returns around 100 errors which I believe are all rooted to this: Error example

This occurs in every .gwt.xml file in my project, all sharing the same link. Also, when I normally compile and run my project, no errors occur at all.

I have already tried searching for similar issues on this topic, all of which have returned with errors that dealt with a different URI (relating to the android APK). The solutions to those don't apply for mine either, as when I attempt to "Fetch external resource" I get the following message:

Error while fetching http://google-web-toolkit.googlecode.com/svn/trunk/distro-source/core/src/gwt-module.dtd

Even though I am not using a proxy.

If it helps, this also occurs in my iOS folder, where the link there is:
