Re: [forge-dev] How to choose which Java EE version ?

Hey Antonio! (Sorry for the late reply, I was gone over the weekend.) Actually we definitely thought about this with Forge 2, and our current plan is to combine the two issues that Vineet linked with the new ProjectType API. So actually your syntax is very close to what we are already working on! Good to have some reassurance, though: https://github.com/forge/core/blob/2.0/projects/api/src/main/java/org/jbo... This is used in the new-project command like so: `new-project --named "blah" --type javaee-7 --version 1.0 --topLevelPackage org.blah` Now, the interesting thing is that depending on the project type, we can also specify additional parameters that will become activated: `new-project --named "blah" --type javaee-7 --version 1.0 --topLevelPackage org.blah --profile *web/full*` So we can do web profile selection as part of the javaee7 project type, or we could just have multiple project types for each profile. It could go either way. On Mon, Aug 26, 2013 at 9:13 AM, Antonio Goncalves < antonio.mailing(a)gmail.com&gt; wrote: > Ok, thanks for pointing these JIRAs.
