    // in the individual module build.gradle files
}
}

        url "https://maven.google.com"
        name 'Google'
    }

}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

When i sync my project i get the following error:

Caused by: org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method implemetation() for arguments [com.android.support:appcompat-v7:28.0.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

I'm unable to solve the error and therefore not able to start my project, Please provide the best solution possible for this error.

回答1:

you just type implementation instead of implemetation (You missed the letter n) :)

//appCompat
implementation "com.android.support:appcompat-v7:$supportVersion"

//lifecycleExtensions
implementation "android.arch.lifecycle:extensions:$lifeCycleExtensionVersion"

org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method implemetation() for arguments [com.android.support:appcompat-v7:28.0.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

You already moved to Androidx. So kindly remove support support:appcompat-v7

implemetation "com.android.support:appcompat-v7:$supportVersion"

Rectify your allprojects{} section. Use google().

allprojects {
    repositories {
        jcenter()
        google()

    }
}
