Multiple javax.inject.Provider implementations and their binding

Hi everyone! Recently I became a freelancer and started to work for one big company. It’s great, I hope to continue work there.And I also started to work on project where Dropwizard stack is used.Naturally, Guice DI framework is used ther.So, today I would like to write an article about how to bind javax.inject.Provider interfaces to their implementation. The thing is that Guice treat javax.inject.Provider specially, and you cannot just to Because Provider is a generic interface, and google care about initializing this Providers.

I needed to fix jenkins job, which is getting info about sonar metrics, and received an error in job console It was weird for me, because I was getting success jobs, everything went right, but as soon as I failed one job due to bad configuration - hell started, and I couldn’t understand why there my job is failing all the time.So I began experiments. After several tries I managed to add prefix clean phase and everything worked. Another problem was that I was building this job with different parameters and depending on specific parameter I was receiving specific console output.But then I understood that the problem was that I had constant artifacts, that were not cleaned. And I was receiving different output because this parameter was a version of plugin , so that’s why I received different output.
