Gradle robolectric project works on OSX computer but not on Linux - 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 ?

Answer 1

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.

Answer 2

The selected answer is correct, and also applies when upgrading Gradle from 2.2.1 to 2.3 on OSX. If you don't add the dependency for testCompile 'org.apache.maven:maven-ant-tasks:2.1.3' then Robolectric tests will fail when the Gradle version is 2.3.
Also noteworthy is that I have a separate module for my Robolectric tests, so I added the new dependency to the build.gradle file in my Robolectric module, NOT my Android app module.
Just got a new Mac, so my old Mac & new Mac are side by side, while I configure the new one. I used Homebrew to build up my new Mac, and wasn't aware that Gradle 2.3 had just been released... That's why the Robolectric tests worked on my old Mac (with Gradle 2.2.1) but not on my new Mac (with Gradle 2.3).
