错误：与项目“：App”中的依赖项“com.android.support：support-annotations”冲突

Question

我试图解决这个梯度错误，我从我的一个朋友那里引进了这个项目，它在他的系统中运行得很好。好像我有以下问题在我的年级。

错误：与项目“：App”中得依赖项“com.android.support：support-annotations”冲突.应用程序(27.0.2)和测试应用程序(25.4.0)的解析版本不同。

只需在您的build.gradle（：app）中添加以下内容即可

configurations.all {
    resolutionStrategy {
        force 'com.android.support:appcompat-v7:26.+'
        force 'com.android.support:support-compat:26.+'
        force 'com.android.support:support-core-ui:26.+'
        force 'com.android.support:support-annotations:26.+'
        force 'com.android.support:recyclerview-v7:26.+'
    }
}
