gwt-module.dtd moved, 301

[kaefert]

Hi there!

I just generated an empty GwtMaterialDesign using the archetype line from
https://gwtmaterialdesign.github.io/gwt-material-demo/snapshot/#gettingstarted
-->
mvn archetype:generate -DarchetypeGroupId=com.github.gwtmaterialdesign -DarchetypeArtifactId=gwt-material-archetype -DarchetypeVersion=2.1.1

Using this I get a *.gwt.xml file that references http://gwtproject.org/doctype/2.7.0/gwt-module.dtd
sadly this file is not (any more?) available at this address, which makes eclipse display an error.
The way I workaround this issue is to put the gwt-module.dtd right next to the *.gwt.xml file and reference it without a path, which makes eclipse read the file from the same directory.
