How to use FlexPMD

1. Right click on your project in the Package Explorer
   go to FlexPMD>Run FlexPMD:
   

   

2. You can see the results in the FlexPMD View:
   

   

Note：

The reason for FlexPMD not to show any results is probably because you have spaces in the full absolute path to the folder you want to check (e.g. C:usersyourusername…Flash Builder Workspaceyourprojectnamesrc). FlexPMD doesn’t seem to like spaces and crashes silently.

Another important thing is that FlexPMD needs to have the rights to write it’s results to disk. In Windowns 7 this also may cause FlexPMD to crash silently.
You can fix this problem by changing the FlexPMD preferences (Flash Builder>Window>Preferences>FlexPMD) where it says “Java command line” to “java -Xmx256m -Djava.io.tmpdir=C:Users[yourusername]AppDataLocalTemp”
