I'd like to use Google's GXP library in my maven project. I'm new to Maven and having quite a bit of trouble since the .jar is not available in a Maven repository already. From what I've read I should be able to install the jar in my local repository and then make use of it. However, I'm having quite a bit of trouble. Anyone know where I might have gone wrong?

PS C:\Documents and Settings\bmccann\Desktop> mvn install:install-file -Dfile=gxp-0.2.4-beta.jar -DgroupId=com.google -DartifactId=gxp -Dversion=0.2.4-BETA -Dpackaging=jar
