How to resolve duplicated gradle Dependency issues

Question

I have tried to test my code with robolectric. Problem is that it has duplicated References. e.g.

java.lang.RuntimeException: java.lang.RuntimeException: Duplica         


        

Answer 1

Finally get the test running. I've excluded all libs with duplicated classes:

testImplementation ("org.robolectric:robolectric:4.3"){
    exclude group: 'org.apache.maven', module: 'maven-artifact'
    exclude group: 'org.apache.maven', module: 'maven-artifact-manager'
    exclude group: 'org.apache.maven', module: 'maven-model'
    exclude group: 'org.apache.maven', module: 'maven-plugin-registry'
    exclude group: 'org.apache.maven', module: 'maven-profile'
    exclude group: 'org.apache.maven', module: 'maven-project'
    exclude group: 'org.apache.maven', module: 'maven-settings'
    exclude group: 'org.apache.maven', module: 'maven-error-diagnostics'
    exclude group: "org.apache.maven.wagon"
}

Not all possibilities tested but a simple test worked already.

Answer 2

The solution for me was to ensure that I was not requiring Robolectric in my androidTestImplementation dependencies.

Once I fixed that, I did not have any conflicts to fix.

Answer 3

This probably could be written in more general way:

testImplementation ("org.robolectric:robolectric:4.3") {
    exclude group "org.apache.maven.wagon"
    exclude group "org.apache.maven"
}

or even:

testImplementation ("org.robolectric:robolectric:4.3") {
    exclude group: "org.apache.maven", name: "maven-ant-tasks"
}

because it is maven-ant-tasks of pluginapi, which pulls in org.apache.maven dependencies.

Answer 4

I've encountered the same issue and the thing that helped me was that I had defined the Roboelectric dependency twice in Gradle file one with androidTestImplementation and the other with testImplementation so when I removed the first part problem solved!!!
