Create a project from gwt-maven-plugin archetype using m2eclipse.
Set gwt.version to 2.0.3

Error:

Although it has the symptoms of MGWT-24, the underlying cause is different.
Running build in debug mode reveals the culprit:
Here is the log of the command execution that fails:

If you look at the command line carefully you will notice that classpath
entries for dependency jars contain spaces, and entries for plugins
contain'%20' instead.
While it's fine to do such substitution in URI's, Windows does need a space,
not '%20'.
As a workaround, if you edit settings.xml and set <localRepository> to a
directory that does not contain spaces, the build succeeds.
