Answer 1

The duplication comes from jersey client. It depends on both org.glassfish.hk2.external:javax.inject and javax.inject:javax.inject.
So, you need to exclude one of them:
dependencies {
...
compile ('org.glassfish.jersey.core:jersey-client:2.22.1') {
exclude group: 'javax.inject', module: 'javax.inject'
}
...
}
I try to use org.glassfish.jersey.media:jersey-media-moxy in my project and had to apply the same exclusion for that dependency too - likely it will be the same for org.glassfish.jersey.media:jersey-media-json-jackson.
