Using Guice to Inject something in build (publish) steps

[Kirill Merkushev]

Hello!

 

I want to replace all static interactions in my plugin with DI.

 

But when i use @Inject annotation on @Extension class - all works perfectly, but with any kind of Describable (which should be created same as any extension i think) it doesn't work.

 

I have an example https://gist.github.com/lanwen/553b51c9d2227eaad435

 

The main idea - that a want injected instance in perform method, but it only injected when i do Jenkins.getInstance().getInjector().injectMembers(this);

 

Can somebody help to clarify why this doesn't injected automatically?

 

Thanks!

`Describable`s are not singletons or extensions and cannot be used
with `@Inject`.

Is it possible to create some @AutoWired and @Component spring analogues under jenkins code to not deal with constant Jenkins.get.. calls?

Actually what you are trying to do has nothing to do with
`Describable`, but with `Builder`. At any rate, that does not work
either. DI in Jenkins is very limited. You can only wire extensions,
or `Jenkins`, to one another. If you want my opinion, you should not
bother with it at all.

If you want a second opinion. You should not bother with even thinking about doing it at all.

I've described only builder, but the question is about any describable (customized too).

Thanks for the quick answers!

It really sorry that i cant do it. It can simplify unit-testing a lot.
