终于让我找到了问题的解决方案

v1或当我更新gradel版本没有build.gradle（Proejct Level）
classpath 'com.android.tools.build:gradle:2.3.0'

我的旧的build.gradle（项目级别）

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.2.3' 
    } 
} 

allprojects { 
    ........ 
} 

task clean(type: Delete) { 
    ...... 
} 

我更新的build.gradle（项目级别）

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.0' 
    } 
} 

allprojects { 
...... 
} 

task clean(type: Delete) { 
...... 
}
