Any help is much appreciated!

I moved out the externalNativeBuild outside of buildTypes and have put it under android. It started working.

android {
....
...
   buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            debuggable true
            minifyEnabled false

            ndk {
                abiFilters   "armeabi-v7a", "x86"
                moduleName "HelloJNI"
            }
        }
    }

    externalNativeBuild {
        ndkBuild {
            path "src/main/jni/Android.mk"
        }
    }

    buildTypeMatching 'debug', 'release'
...
....
} // end of android

This produces an error: **Could not find method buildTypeMatching() for arguments [debug, release] on object of type com.android.build.gradle.AppExtension.** — IgorGanapolsky, Apr 09 '18 at 15:52

Try replacing implementation with api only for last two project dependencies:

commonandroidutils
wimutils

Documentation states that:

The dependency is available to the module at compile time, and it's also available to the consumer of the module at compile time and runtime. This configuration behaves just like compile (which is now deprecated), and you should typically use this only in library modules. App modules should use implementation, unless you want to expose its API to a separate test module.

Reference: Migrate to Android Plugin for Gradle 3.0.0

Not sure, but give it a try. Hope it helps.

I'm not sure how this is possible. It looks like you have a mismatch between the Gradle plugin itself and its dependencies that provides the WaitableExecutor class.

However you mention Gradle 1.5 and this is a problem.

The plugin version 0.3 was compatible with Gradle 1.3-1.4 The new version release last week, 0.4 is compatible with Gradle 1.6+

Make sure you use 0.4 and the new Gradle version.
