Hello,  
I’m receiving this error:

```
com.android.builder.testing.ConnectedDevice > runTests[test(AVD) - 5.1.1] FAILED 
	com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: INSTALL_FAILED_DEXOPT

```

You can see it [here](https://travis-ci.org/GuilhE/SharedPrefsUtils/builds/573452059).  
Also, this is my [travis.yml script](https://travis-ci.org/GuilhE/SharedPrefsUtils/jobs/573452059/config) (that was working before updating gradle plugin).

Can you give me some hints about this problem, is it a missing configuration?  
Thanks.
