Add className and path parameters in CLI

EDIT:

See comment https://github.com/quarkusio/quarkus/issues/14437#issuecomment-1067739526

Legacy:

They are already definable as codestart data: https://github.com/quarkusio/quarkus/blob/master/independent-projects/tools/devtools-common/src/main/java/io/quarkus/devtools/codestarts/quarkus/QuarkusCodestartData.java#L32-L39

We need to plug them to distinct parameters (resteasy.class-name, resteasy-reactive.class-name, …) instead of a generic one in the CreateProjectMojo and the io.quarkus.cli.Create: https://github.com/quarkusio/quarkus/blob/main/independent-projects/tools/devtools-common/src/main/java/io/quarkus/devtools/codestarts/quarkus/QuarkusCodestartData.java#L39-L46

This issue also includes updating the guides to use those new parameters.

@cristian-com I think we should wait for the new CLI before doing that one. Let me find you something 😃

To give a bit of context, the problem is that when selecting multiple codestarts (i.e: resteasy + spring-web, …) then path and className parameters are ambiguous. The current behavior is to ignore them in that case.

With a bit more feedback on how codestarts are used, it seems that beside the basics (groupId, extensions…) customizing the generated code is not a strong need and would be complex to maintain and document with that many extensions. Still we have some “main” extensions resteasy, resteasy-reactive, spring-web and maybe some other in the future for which it is nice to configure the className and the path.

So, in the end, I believe we should:

• keep the current behavior and ignore when ambiguous
• un@Deprecate the className and the path in the Maven plugin
• add className and the path in the Quarkus CLI.

FYI:

• If the packageName is defined, the package part of the className is ignored
• If the packageName is not defined and the full qualified className is defined, it is used as packageName
• If the packageName is not defined at all, the groupId is used as packageName
• Else org.acme is the default
