Android Studio 3.0 Error. Migrate dependency configurations for local modules

Question

I recently installed the latest Canary build of Android Studio which is currently using the Android Gradle plugin 3.0.0-alpha4 .

I now get a error:

Error:Failed to resolve: Could not resolve project :MyLib. Required by: project :app 

I has read: Migrate dependency configurations for local modules

dependencies   {  // This is the old method and no longer works for local // library modules: // debugCompile project(path: ':foo', configuration: 'debug') // releaseCompile project(path: ':foo', configuration: 'release')  // Instead, simply use the following to take advantage of // variant-aware dependency resolution. You can learn more about // the 'implementation' configuration in the section about // new dependency configurations. implementation project(':foo')  // You can, however, keep using variant-specific configurations when // targeting external dependencies. The following line adds 'app-magic' // as a dependency to only the 'debug' version of your module.  debugImplementation 'com.example.android:app-magic:12.3'  } 

I changed:

releaseCompile project(path: ':MyLib', configuration: 'appReleaseApp') debugCompile project(path: ':MyLib', configuration: 'appDebug') 

to:

implementation project(':MyLib') 

but i still have this error: Error:Failed to resolve: Could not resolve project :MyLib.

lib gradle:

Google added more instruction how to solve it: Resolve build errors related to dependency matching

Cause of build error:

Your app includes a build type that a library dependency does not.

For example, your app includes a "staging" build type, but a dependency includes only a "debug" and "release" build type.

Note that there is no issue when a library dependency includes a build type that your app does not. That's because the plugin simply never requests that build type from the dependency.

Resolution

Use matchingFallbacks to specify alternative matches for a given build type, as shown below:

// In the app's build.gradle file. android {     buildTypes {         debug {}         release {}         staging {             // Specifies a sorted list of fallback build types that the             // plugin should try to use when a dependency does not include a             // "staging" build type. You may specify as many fallbacks as you             // like, and the plugin selects the first build type that's             // available in the dependency.             matchingFallbacks = ['debug', 'qa', 'release']         }     } }
