Maven GlassFish plugin: asadmin CreateProcess error=193

Normally I would just go to the java.net site and look up what the error code I am getting is about but their web site is currently offline. Basically I am following this guide:

http://pookey.co.uk/wordpress/archives/95-getting-started-with-glassfish-using-maven

to try and get an example maven web application deployed on my GlassFish application server. My POM file is as follows:

My GlassFish application server is up and running, but I get the following error message when I execute

mvn war:war glassfish:deploy

Failed to execute goal org.glassfish.maven.plugin:maven-glassfish-plugin:2.1:
deploy (default-cli) on project hello-world: Deployment of myPathToMavenProject.war 
has failed. IOException: Cannot run program "myPathToGlassfishFolder\bin\asadmin": 
CreateProcess error=193, %1 is not a valid Win32 application -> [Help 1]

This is an issue under Windows as described here. Deleting the asadmin (without extension) file should help until it is fixed.
