Resolved versions for app (26.1.0) and test app (27.1.1) differ.错误解决

今天碰到这个问题,记录一下

 Error:Execution failed for task ':app:preDebugAndroidTestBuild'. > Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/tes 

解决方案:

app中的build.gradle中

dependencies中添加:

androidTestCompile('com.android.support:support-annotations:26.1.0') {
    force = true
}

 

dependencies {
    androidTestCompile('com.android.support:support-annotations:26.1.0') {
        force = true
    }
    
}
