大家好，我希望你能帮助我，

Hi guys I hope you can help me,

如果我想运行我的应用程序，我会收到此错误。

If I want to run my Application, I get this error.

错误：任务'：app：transformClassesWithInstantRunForDebug'的执行失败。

My Gradle看起来像这样

My Gradle looks like this

pply plugin: 'com.android.application'

android {

    defaultConfig {

        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'

}

推荐答案

当我尝试在项目级别升级gradle插件版本时发生这种情况。它是

This happened with me when I tried to upgrade gradle plugin version in my project-level. It was

classpath'com.android.tools.build:gradle:2.1.3'

classpath 'com.android.tools.build:gradle:2.1.3'

然后我将它升级到2.2-beta，然后我得到了同样的错误。

And then I upgraded it to 2.2-beta, then I got the same error you are getting.

将它设置回'2.1.3'为我修复它

Setting it back to '2.1.3' fixed it for me
