I inherited a project from another developer. The project hasn't been touched in a year. When I try to build the project, I get a bunch of "unable to resolve dependency" errors. What do these mean? What is missing from the project? Below are some examples of the build errors I'm getting: ERROR: Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.google.code.gson:gson:2.8.5. Show Details Affected Modules: app ERROR: Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve androidx.constraintlayout:constraintlayout:1.1.3.

You even have both versions for ConstraintLayout: implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha5' // (...) implementation 'androidx.constraintlayout:constraintlayout:1.1.3' You need to choose the support library you want to use and adjust all your dependencies accordingly (making sure all your 3rd party libraries can run on AndroidX if that's what you decide to go with). So the dependencies should start with
Keep in mind that the version 10.* of Butterknife only works with AndroidX, so if you decide to use the original Support Library, you will have to use the version 9.* instead Also, in your I'm following the steps on android but in android studio the build fails with the message. Gradle 4.1( I don't know if this is related) Could not resolve project :react-native-navigation. Required by: project :app Unable to find a matching configuration of project :react-native-navigation: None of the consumable configurations have attributes. |
