enable gradle for extension development

[ppalaga]

A followup of #2113 . A Maven mojo was added via #3191 (see also #3321 )

If nobody start to work on it, i will try.

request makes sense but this would be post v1. I would actually prefer we had a native qctl or qli cli to do the bootstrapping. Its really backwards we have to tell users to install gradle or mvn ( + java) when we could just generate the initial project for them .... or even just give them a bit.ly url to curl to get a zip from code.quarkus.io.

No need to strictly use either mvn or gradle for this step is my point ;)

This would be largely beneficial for the expansion and adoption of Quarkus. We are incredibly interested in using Quarkus because it's a great framework and the extensions really open up possibilities for my team. However, our CI/CD architecture relies on Gradle (and many can argue that Gradle is superior) so being able to develop extensions with Gradle would be great!

sorry I have no more time to work on quarkus. But you can try a contribution.
It's simple:
just like https://github.com/quarkusio/quarkus/blob/master/devtools/maven/src/main/java/io/quarkus/maven/CreateExtensionMojo.java

create a task here:
https://github.com/quarkusio/quarkus/tree/master/devtools/gradle/src/main/java/io/quarkus/gradle/tasks

I think this one can be close as the cli will handle this right @maxandersen ?

[maxandersen]

The cli Would be the place to have the command yes. Not sure if all is in place to develop a quarkus extension with gradle - @aloubyansky ?

[aloubyansky]

It's definitely possible to develop extensions with gradle. As to the tooling support, the maven extension-descriptor goal is pretty advanced now. But we have to start with the equivalent gradle support at some point. So, let's.

[glefloch]

I misunderstood the issue. I will start working on this next week then :)

[aloubyansky]

I didn't mean to add createExtension as a gradle task though. We would have a cli command for that but then we'd want some support from the gradle plugin in terms generating the proper extension metadata and descriptor.

[glefloch]

Yes, when I mention that the issue could be close as the cli is here I was thinking about the project generation part. But as you mentioned in your previous comment, the gradle plug-in don't do anything regarding the extension property file. That could be handled some how in the plug-in.

[maxandersen]

+1 I've updated issue title to reflect this. Have create extension cli command support gradle but for that have the remaining things done we still only have in maven ext plugin
