Refreshing Xcode Project Settings throws NullPointerExceptor?


(Richard Hu) #1

I just updated my libGDX app’s Gradle plugin from 2.2.0 to 4.5.1 to try to get MOE to work. However when I executed Multi-OS Engine Actions > Inject/Refresh Xcode Project Settings, the build failed and returned

FAILURE: Build failed with an exception.

* What went wrong:
java.lang.NullPointerException (no error message)

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 0s

Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0.
See https://docs.gradle.org/4.5.1/userguide/command_line_interface.html#sec:command_line_warnings

I then tried running ./gradlew build --warning-mode=all which initially failed but after I fixed a few things in my build.gradle, the Gradle build was successful. After this, I tried refreshing my Xcode project settings but the same error popped up.

Does anyone know how to fix this? The NullPointerExceptor tells me absolutely nothing so I have no idea where to even begin.

Thank you!

UPDATE

I ran the Multi-OS Engine Gradle Build, which gave me some more detailed information. The build failed and returned

Thanks!
