@gsmet @ia3andy could you review this please since my internet access will be very sporadic over the next week or so?

Thanks

[ia3andy]

@geoand correct me if I am wrong, I see two potential problems:

1. I am not sure but it seems that the result of the create may depend on the order in which the builder is called
2. when I used it in the launcher, I added the extensions after creating the project, do you assume that it's supposed to be effective only at creation time?

[geoand]

I won't really be able to review for a few days, so up to you really to request changes if you think they are necessary 😊

[ia3andy]

@gsmet, what's your opinion? I am not totally sure, but I think it would make more sense to have this feature part of the AddExtensions mechanism. It would create the Spring file, even when adding the spring extension in an existing project.

[gsmet]

Thanks for your contribution, I added a few comments inline.

[gsmet]

@ia3andy I don't know. I'm not very excited at the idea of creating new files when adding an extension to an existing project.

[ia3andy]

@gsmet I don't know either, but having different behavior (before and after) is as troubling to me.. maybe this should not be treated automatically with the extension but more as an option in the create command?

[gsmet]

I don't think it's an issue. For me it's two different things:

• you create a project, it comes from a template and you have a few examples set up
• you have an existing project, you add an extension and you certainly don't want it to add random files to your project.

I don't think it's an issue.

[ia3andy]

@gsmet ok, so I guess this PR includes two features:

• Being able to set the extensions directly in CreateProject
• Being able to detect and add extra content depending on the set of extensions (in this case for Spring) in CreateProject

The order of call seems to still be an issue, I'll update my "Change Request"..

[geoand]

@aureamunoz you will also have to rebase onto the latest master since there are some conflicts

[ia3andy]

@aureamunoz in your implementation, the extensions in CreateProject are only used to detect Spring, you could also use them to write them in the pom.xml directly at project creation (instead of having to do it in another step). I guess that what @gsmet said to do in another PR, right?

[geoand]

@gsmet @ia3andy unless you have any objections, I plan to merge this

[gsmet]

@geoand feel free to do it, I trust your judgement on this one.

[geoand]

Thanks!
Merging with what we have, we can certainly improve in the future - I suppose @ia3andy will have more ideas on this part

changes have been made

[geoand]

Tested locally and things work as expected.

Thanks for the PR!
