as gradle 编译错误解决办法

这些as工程，报错，为了以后，好找答案，总结如下：保持更新并

1.

Resolved versions for app (23.4.0) and test app (23.1.1) differ.

具体的报错：

Warning:Conflict with dependency ‘com.android.support:support-annotations’. Resolved versions for app (23.4.0) and test app (23.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

Error:Execution failed for task’:app:prepareDebugAndroidTestDependencies’.

也就是说“support-annotations”报了错，

我的引用：

androidTestCompile “com.android.support:support-annotations:$rootProject.supportLibraryVersion”

网络解决案例

后来就将一些testcompile给注释就好了，具体，还是项目的gradle配置不大了解，我后一篇就写一个gradle的；

2.

Error:Failed to resolve: junit:junit:4.12

href=”openFile:E:/AndroidExampleSjt4444/android-architecture-todo-mvp/app/build.gradle”

Open File href=”open.dependency.in.project.structure”>Show in Project Structure dialog

解决办法：

其实这个错误并非把testCompile ‘junit:junit:4.12’注释或删除掉，在stackoverflow中有明确的原由和解决方法，只需在Application的gradle文件中添加maven { url ‘http://repo1.maven.org/maven2’ }
