無法解析外部依賴 com.android.tools.build:gradle:2.2.2

Question

出於某種原因，travis build很難解決依賴關系。

A problem occurred configuring project ':app'.
Could not resolve all dependencies for configuration ':app:_debugApk'.
A problem occurred configuring project ':mortar'.
 Could not resolve all dependencies for configuration ':mortar:classpath'.
 Cannot resolve external dependency com.android.tools.build:gradle:2.2.2 because no repositories are defined.

無法解析外部依賴 com.android.tools.build:gradle:2.2.2 因為沒有定義存儲庫

在mortar/build.gradle您沒有存儲庫。

buildscript {
  dependencies {
    classpath 'com.android.tools.build:gradle:2.2.2'
  }
}

但是，你不應該在那里需要它......你的/build.gradle可以設置它。

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    // *** Add this *** //
    buildscript {
        repositories {
            jcenter()
        }
    }

    repositories {
        jcenter()
    }
}

真的，您的代碼庫中根本不需要mortar 。

app/build.gradle

dependencies {   
    ...
    // compile project(':mortar') // ** Remove this ** //
    compile 'com.squareup.mortar:mortar:(latest version)'
}
