Gradle 'Could not resolve all dependencies for configuration' in Jersey/JAX-RS project

Question

I would like to put JSON dependency in the build.gradle, in order to fix the error MessageBodyWriter not found for media type=application/json. In my previous question I learned that it was very likely that I did not include JSON as dependency in my build.gradle file.

I added the dependency as shown below (line 8, last compile)

apply plugin: 'war'
apply plugin: 'jetty'

dependencies {
    compile fileTree(dir: 'lib', include: '**/*.jar')
    compile(project(":qa-common"))
    compile(project(":alm"))
    compile 'org.glassfish.jersey.media:jersey-media-json-jackson:2.3.10'
}

jettyRun {
    httpPort = 8080
    reload = 'automatic'
    scanIntervalSeconds = 2
    daemon = false
}

Now I am getting the error of Could not resolve all dependencies for configuration'

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':qa-automation-console:compile'.
> Cannot resolve external dependency org.glassfish.jersey.media:jersey-media-json-jackson:2.3.10 because no repositories are defined.

BUILD FAILED

I am checking whether I have included the correct version of gradle and Jersey (in web.xml I see 2.5 but 2.5 still gives the same error). In my jersey server side code the only package related to jersey was import org.glassfish.jersey.server.mvc.Viewable;

Anyone give me a clue what I need to add?

Define repositories in your build.gradle like following.

repositories {
      maven  {
          url "http://repo1.maven.org/maven2"
      }
}

Or following

repositories {
    mavenCentral()
}

Gradle Help Chapter 8. Dependency Management Basics 8.5. Repositories gives other examples.

You should also change your dependency according to existing versions. I linked version page since you request "version 2.3.10" which does not exist in maven repository.

dependencies {
    compile 'org.glassfish.jersey.media:jersey-media-json-jackson:2.5'
}
