Is that what is messing everything up? Should I just recreate my project with a name without a dot in it?
Yes, the dot is actually a feature we added for JBoss users who needed to be able to deploy projects with custom JAR names (for HAR, SAR, RAR, etc. support in JBoss).
However, a dot in the EAR Project name should be ignored IMO, I’ll file this so a dev can comment on it and possibly fix it. Sorry for the trouble.
