Android Studio报错：DefaultAndroidProject : Unsupported major.minor version 52.0

今天使用Android Studio 2.0打开我之前的项目时，编译报了如下错误：

Error:Cause: com/android/build/gradle/internal/model/DefaultAndroidProject : Unsupported major.minor version 52.0

其中build.gradle文件内容如下所示：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-alpha4'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

如上所示，gradle的版本为2.2.0-alpha4。这是因为今天下了一个Android Studio 2.2 Preview4,然后将该项目在Android Studio 2.2 Preview4中打开过,原来的gradle版本是2.0.0

解决办法

方法1

直接不用Android Studio 2.0了，转而使用Android Studio 2.2 Preview4编译该项目，继续开发。

方法2

在Android Studio 2.0中继续开发该项目，修改build.gradle文件内容，将gradle版本改成2.0.0，代码如下：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
