Getting MessageBodyWriter not found for media type=application/json

问题

I've tried everything...can't figure out why I'm getting this exception. What's interesting is that in my IDE (Intellij) everything works without a hitch. Can't figure this out...giving up.

Do any of you have any suggestions?

    testCompile 'org.objenesis:objenesis:1.2' // For mocking final classes
    testCompile group: 'junit', name: 'junit', version: '4.9'
}

Getting the following:

I was getting the same error for 2.22.1 I added the following dependency and it worked.

    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-json-jackson</artifactId>
        <version>2.22.1</version>
    </dependency>
