When you run into problems with PowerShell's interpretation of arguments to be passed to a console EXE, try using the echoargs.exe utility that comes with the PowerShell Community Extensions. With this tool you can see how PowerShell supplies the arguments to the EXE e.g.:

PS> echoargs mvn clean install -Dmaven.test.skip=true
Arg 0 is 
Arg 1 is 
Arg 2 is 
Arg 3 is <-Dmaven>
Arg 4 is <.test.skip=true>

PS> echoargs mvn clean install '-Dmaven.test.skip=true'
Arg 0 is 
Arg 1 is 
Arg 2 is 
Arg 3 is <-Dmaven.test.skip=true>

Short answer - use quoting '-Dmaven.test.skip=true'
