Fortunately there is a note on the plugins page about this
http://plugins.intellij.net/plugin/?idea&id=265

v1.0.1 is from IDEA but 1.0.3 is available here

There have been no commits to the source code since 2009 and I didn't get a response from my email yet.
Can someone from JetBrains update the version available from within the repository to the latest version?

Even better would be for JetBrains to make this core functionality since scripts are often used to launch Java applications.
