Generate junit test report fails on Jenkins with Android N device

RDev · July 29, 2016, 7:35am

Gradle Version: 2.14.1
Operating System: Jenkins (Win 7 64bit), Testdevice (Nexus 9 OS 7.0)
Is this a regression? If yes, which version of Gradle do you know it last worked for?

Hi,

thanks for your report. Could you give a little bit more context? Also consider sharing a Build Scan.

RDev · August 2, 2016, 11:22am

We have a project with the following structure:

-MyProject
    -MyModule
        -MyFlavor1
        -MyFlavor2
        -MyFlavor3
        -MyFlavor4
        -MyFlavor5
        -main
        -androidTest
            -FlavorX
                ApplicationTest.java

When you create a new flavor in AndroidStudio, then per default AS generates an ApplicationTest.java in the androidTest package for each flavor without any testcases.
In our case, these class exists just for one flavor. Then if the connectedFlavorXDebugAndroidTest task gets executed, it ends up in the following Exception:

br> BUILD FAILED

After i delete the “FlavorX” folder with the ApplicationTest.java the build is successful.

Stefan_Wolf · August 22, 2016, 1:09pm

Could you try with Gradle 3.0? The Android plugin with version 2.2.0-beta2 should work with Gradle 3.0. Also, a self contained example would be very helpful.

We had the same error. Turned out it’s not Gradle but calling deprecated API in ApplicationTest.java
Just delete the ApplicationTestCase and the error should be gone
