Cannot add a configuration with name 'testComp

问题:

When updating to gradle plugin 1.1.0 I kept getting the following error

Cannot add a configuration with name 'testCompile' as a configuration with that name already exists

I am also using the Robolectric gradle plugin from here, v0.14.0.

The new gradle 1.1.0 plugin adds additional unit test support, so I suspect the gradle and Robolectric plugins are battling for use of 'testCompile,' though I'm not sure how to resolve this.

To fix that issue i did the following:

Added the following to my build gradle script:

 apply plugin: 'org.robolectric'

 dependencies {
    classpath 'org.robolectric:robolectric-gradle-plugin:1.0.0'
 }

This wouldnt work for me with gradle version 1.1.0 though. I had to use 1.1.0-rci which is still only in experimental phase. So i added the following to my project build.gradle:

  dependencies {
    classpath 'com.android.tools.build:gradle:1.1.0-rc1'
}

Ran sync project with gradle files and the issue was corrected. Hope this helps.

Looks like the fine people over at Robolectric have updated their plugin to resolve the issue.

Use Robolectric Plugin v1.0.0 and you will be able to update gradle plugin and also run your Robolectric tests.

I had the same issue and I fixed it.

In my case I had my

apply:plugin statements below the configurations I have added them above and the already exists issue is fixed.
