androidstudio运行时总是报错

Question

Error:Gradle: A problem occurred configuring root project 'MyApplication'. > Could not resolve all dependencies for configuration ':classpath'. > Cannot resolve external dependency com.android.tools.build:gradle:1.3.0 because no repositories are defined. Required by: :MyApplication:unspecified
不是代码问题，试过重新安装配置jdk和下载插件sdk，通过新生成项目验证运行效果和dos系统下javac的确定没问题；
现在是系统的资源文件build.gradle总是报1.3.0的错，网上下载了一个1.5.0的架包导进去，但是还是不行，请大神指点

版本不一致，你下了1.5的就改成1.5的
