问题描述

我试图编译我的Andr​​oid Studio中项目时收到以下错误：

I'm getting following error when trying to compile my project in Android Studio:

Gradle: error: diamond operator is not supported in -source 1.6

我有1.7设为目标中的所有项目preferences我发现。此外，根据1.7 SDK显示在项目SDK的路径是对Java 1.7的安装正确的路径。

I have 1.7 set as target in all project preferences I've found. Also the path displayed in project SDK's under 1.7 SDK is correct path to java 1.7 installation.

甚至当我运行在终端Java的版本，它告诉我，我java的运行1.7

Even when I run java -version in terminal, it tells me I'm running on java 1.7.

/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home

错误不会消失。我如何消除错误？

推荐答案

Java 7的支持，在构建工具添加19现在可以使用的功能，如钻石运营商，多抓，尽量-与资源，在开关串等添加以下到你的的build.gradle 。

Java 7 support was added at build tools 19. You can now use features like the diamond operator, multi-catch, try-with-resources, strings in switches, etc. Add the following to your build.gradle.

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

摇篮1.7+的Andr​​oid插件的gradle 0.6 +是必需的。

Gradle 1.7+, Android gradle plugin 0.6.+ are required.

请注意，只有具有资源尽量要求的minSdkVersion 19.其他功能适用于previous平台。

Note, that only try with resources require minSdkVersion 19. Other features works on previous platforms.
