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

BTW, if most of the information is giving at project creation, do we still need to explicitly setup Java EE components ? At the moment we have the following : beans setup ejb setup faces setup jms setup jstl setup jta setup persistence setup --provider ECLIPSELINK --container GLASSFISH_3 --jndiDataSource rest setup --activatorType servlet setup --quickstart soap setup validation setup --provider JAVA_EE --traversableResolver Most of these commands do not have parameters (except for persistence, rest, validation). So why not activate them by default ? Something like : "if the command beans-new is entered, Forge would go if beans is not setup, then I invoke beans-setup", "if the command ejb-new is entered, Forge would go if ejb is not setup, then I invoke ejb-setup" That would save some bugs (developers forgetting to setup things), less typing and shorter scripts. What do you think, could this be possible for most of the cases ? Antonio 2013/8/26 Lincoln Baxter, III <lincolnbaxter(a)gmail.com <mailto:lincolnbaxter@gmail.com>> 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 <mailto:antonio.mailing@gmail.com>> wrote: Ok, thanks for pointing these JIRAs.

I don't think we have worked out the behavioral needs, but the idea is to allow the container or Java EE version dictate the Maven artifacts and versions that would be declared in the project during generation.
