[WM21] Gradle failure to build

Hello

I would like some help with Gradle please
This is the first time I have tried to build an apk file for this project as previously it was V20

The error message from Gradle is :

Failure creating the Android application named <C:\JCA_V21_Remote\AndroidRemote\Exe\CCF-BMS.apk>.


Command Line: "C:\Program Files\Java\jdk1.8.0_20\bin\java.exe" "-Dorg.gradle.appname=C:\JCA_V21_Remote\AndroidRemote\Android\Generation" -classpath "C:\Gradle\gradle-2.9\lib\gradle-launcher-2.9.jar" org.gradle.launcher.GradleMain assembleRelease -b build.gradle


Error returned:

FAILURE: Build failed with an exception.

I haven't a clue what that means but I have started a search in Google but in the meantime any help would be appreciated
