Auto-discovery of MessageBodyWriter broken?

[vasukisesh]

Trying to enable auto-discovery of a MessageBodyWriter implementation as described in the docs.

However, if I add an @Provider annotation on my class, Dropwizard fails to start up, and I get the following stacktrace:

I'm using Dropwizard 2.1.1 and Guicey 5.6.1. Has anyone else see this?

If you add the following dependency it should work (as a workaround):

implementation 'org.glassfish.jersey.media:jersey-media-jaxb:2.36'

It is a transitive dependency for dropwizard-testing and I missed that: it was impossible to detect in tests (using dropwizard-testing). I'll investigate this further.

[vasukisesh]

Yes, thanks for that workaround! Will this be fixed in the next release?

[xvik]

Yes, of course
