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!

[Dufgui]

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

[rdehuyss]

Would love to be able to add a real Quarkus extension in JobRunr. JobRunr uses Gradle as build tool and I prefer not to mix this with maven.

[aloubyansky]

@rdehuyss do you mean you want to develop a Quarkus extension for the JobRunr? I can help you set it up in Gradle.

[rdehuyss]

@aloubyansky , that would be great! Is there perhaps an example somewhere I missed?

[aloubyansky]

Are you on Zulip? That'll be easier to communicate.

[glefloch]

I can help too if needed.

[rdehuyss]

Are you on Zulip? That'll be easier to communicate.

Not yet, I'll join in about an hour.

[aloubyansky]

Ping @aloubyansky and @glefloch when you're there.

which is the state of this? I saw in the devtool directory that there is a gradle-extension-plugin but I don't see any guide on how to use it.

I'm trying to use the gradle io.quarkus.extension plugin in a multi-module setup, one of my subprojects has the dependency set in the build.gradle and I have the project structure created (deployment and runtime directories) but I see this in the log when gradle is configuring the project:

> Configure project :myproject-quarkus-extension
Unable to find deployment project with name: deployment. You can configure the deployment project name by setting the 'deploymentProject' property in the plugin extension.

Note that there is no deploymentProject property in the plugin configuration maybe this should be updated

Do you know of any extension using Gradle?

[aloubyansky]

It's supposed to be https://quarkus.io/guides/writing-extensions#using-gradle

[glefloch]

Right there is a minimal quarkus extension gradle plugin. It has some limitation such as unit test support that need to be adresse before it can be fully used.
Also, if you want examples, there are some gradle test samples that are using the plugin : https://github.com/quarkusio/quarkus/tree/main/integration-tests/gradle/src/main/resources/conditional-dependencies/ext-a

and also, this project have a gradle based quarkus extension but without using the plugin: https://github.com/jobrunr/jobrunr/tree/master/framework-support/jobrunr-quarkus-extension

Regarding your error, I will update at least the error message, thanks for reporting it.

[fooock]

thank you for pointing me in the right direction! 😀
