Gradle robolectric project works on OSX computer but not on Linux

Question

I'm using the same version of Gradle, 1.7 jdk thus not exactly the same version.

The main complain of the testing is :

java.lang.NoClassDefFoundError: org/apache/maven/artifact/ant/DependenciesTask Caused by: java.lang.ClassNotFoundException: org.apache.maven.artifact.ant.DependenciesTask

I've tried to clean gradle cache in order to re download all dependencies. Also i've tried to clean the project.

This didn't work.

What variables can affect the execution of a gradle test ?

To me there is:

• Gradle itself
• Java version of the sdk
• Internet connections problems

What else can be interfering ? Are plugin versions platform dependant ?

I also ran into this issue on Linux but not OSX. I found a work-around by adding

org.apache.maven:maven-ant-tasks:2.1.3

to my 'testCompile' dependencies.

dependencies {
  repositories {
    mavenCentral()
  }
  testCompile 'junit:junit:4.12'
  testCompile 'org.apache.maven:maven-ant-tasks:2.1.3'
  testCompile 'org.robolectric:robolectric:2.4'
  testCompile 'org.mockito:mockito-all:1.9.5'
}

I don't know why maven-ant-tasks isn't getting fetched on linux. It appears to be a valid dependency of robolectric.
