> > Now when I run Java with -jar, like this:
> > java -jar "%~dp0\lib\BuildTools-1.0.6-SNAPSHOT.jar" "%~f0"
> > com.infotrustgroup.buildtools.commands.Build %*
> >
> > I get the following exception:
> > Exception in thread "main" java.io.IOException: invalid header
> > field name: gmaven-runtime-1.5-Extension-Name
> > at java.util.jar.Attributes.read(Attributes.java:416)
> > at java.util.jar.Manifest.read(Manifest.java:182)
> > at java.util.jar.Manifest.<init>(Manifest.java:52)

> > java.util.jar.JarFile.getManifestFromReference(JarFile.java:160)
> > at java.util.jar.JarFile.getManifest(JarFile.java:146)
> >
> > I believe this is happening because of the dot ('.', or period) in the
> > name. If I use
> > gmaven-runtime-default, this does not happen. If set <addExtensions/
> > > to "false", it also does not happen. So this is fairly easy to
> > work around, but it is also pretty difficult to troubleshoot unless
> > you know where to look.
> >
> > Note that the code in the stack trace isn't mine. This is happening
> > in Java, before my code ever gets called.
> >
> > This one is pretty hard to produce at random, though it is
> > repeatable. You have to be running compiled Groovy from within a
> > JAR where you have set up the MANIFEST with extensions on.
> >
> > One suggestion would be to call the artifact gmaven-runtime and set
> > the version to 1.5, 1.6, whatever - the version of Groovy, plus
> > maybe a point version and RC status. That would work, and it would
> > not break the Java jarring mechanism.
