attached a version of ClasspathBuilder that fixes the problem, for me.

I attached the unmodifid run.cmd, and I also found where I think the problem is. the ClasspathBuilder is putting double quotes around each classpath entry.

I changed the ClasspathBuilder to only surround the entire classpath with double quotes and things work perfectly.

This should be allready fixed in SVN as the
-cp "%CLASSPATH%"
has been replaced by
-cp %CLASSPATH%

so doubled quotes doesn't appear anymore.

I still must check it

I am seeing issues with running the gwt:test goal on windows, and getting this same error. Also using XP.

I can report this as a separate issue if you like, but the exception thrown is the same. As far as I can break it down, TestMojo.getClassPathElementFor is using a URL object, which unnecessarily escapes spaces in strings, and forgets to remove a leading slash in the path. As such, while the GWT jar is passed as
C:\Documents and Settings\username\.m2\repository\com\google\gwt\gwt-user\1.6.4\gwt-user-1.6.4.jar
the gwt-maven-plugin is passed as
/C:/Documents%20and%20Settings/calworth/.m2/repository/org/codehaus/mojo/gwt-maven-plugin/1.1-SNAPSHOT/gwt-maven-plugin-1.1-SNAPSHOT.jar

Windows borks on this - I don't know enough about building maven plugins to say for certain, but would it be possible to create the paths for both jars in the same way that the project roots are obtained?

It doesn't appear to be fixed in the trunk, I checked out the trunk this morning to test the patch I made.

Have this exact same configuration and works fine with latest SNAPSHOT :

set CLASSPATH="D:\java\gwt-maven-plugin\target\it\gwt-compile\src\main\java";"D:\java\gwt-maven-plugin\target\it\gwt-compile\src\main\resources";"D:\java\gwt-maven-plugin\target\it\gwt-compile\target\classes";"C:\Documents and Settings\admin\.m2\repository\com\google\gwt\gwt-user\1.6.4\gwt-user-1.6.4.jar";"C:\Documents and Settings\admin\.m2\repository\com\google\gwt\gwt-dev\1.6.4\gwt-dev-1.6.4-windows.jar"

I can confirm that I still observe the problem with gwt-maven-plugin 1.2, which as of now seems to be the newest version available on the central repo (http://repo2.maven.org/maven2/org/codehaus/mojo/gwt-maven-plugin/). The root cause is that the plugin does not handle spaces in the path correctly. When I changed the Hudson home directory to a path that does not contain spaces everything worked fine.
