问题描述
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,如下图所示:
因此gradle编译的版本就变成了2.2.0-alpha4。而且在Android Studio 2.2 Preview4中可以正常编译。
后来我又切换到了Android Studio 2.0,如下图所示:
但是gradle版本还是2.2.0-alpha4,因此就出现了如题所示的错误:
Error:Cause: com/android/build/gradle/internal/model/DefaultAndroidProject : Unsupported major.minor version 52.0
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 }

然后再重新Sync Project With Gradle Files同步工程,如下所示:
编译成功后的界面如下所示:
至此,bug解决了!
