Getting a warning at startup: "It appears jersey2-guice-spi is either not present or in conflict with some other Jar" about dropwizard-guice

[JanMosigItemis]

I did also encounter this kind of issue and its really annoying. Is there something that can be done about this? Why does the GuiceBundle force the HK2 ServiceLocator?

I'm facing this issue too.

I'm facing this issue too. I'm also wondering if this is the cause for other problem I'm having:

com.google.inject.OutOfScopeException: Cannot access scoped [javax.servlet.http.HttpServletRequest]

Both only appeared after upgrading to dropwizard 1.0.0 and dropwizard-guice 1.0.0.1

I'm not sure how if there's a robust way to avoid this. Looking at the jersey2-guice code, it seems like it logs this warning when the first ServiceLocatorGenerator returned from the ServiceLoader isn't an instance of GuiceServiceLocatorGeneratorStub. In this case, it seems to be an instance of ServiceLocatorGeneratorImpl from the hk2-locator artifact. I tried excluding that artifact but that doesn't work because JerseyGuiceUtils references other hk2-locator classes directly so I get a ClassNotFoundException. I was able to sort of hack around this problem in my test application by moving the jersey2-guice-impl dependency to the front of the list, which made the warning stop printing. Can anyone experiencing this issue try running your app against this commit to see if it fixes it for you as well? If so, I'll cut a release with this change

Confirm. Thank you for the effort!

[jcolaco-nmz]

Yup, it fixes it. Thank you 👍

[jhaber]

Thanks for confirmation, I just released this change as part of version 1.0.0.2 which should show up in Maven central soon

I'm currently experiencing this issue on dropwizard-guice 1.0.0.2.

I am seeing this with DropWizard 1.3.1. We had to downgrade HK2 because injection to @BeanParam stopped working.

I'm seeing this with dropwizard-guice 1.0.6.0
