我使用的是相同版本的Gradle，1.7jdk，因此不是完全相同的版本。
测试的主要抱怨是：
java.lang.NoClassDefFoundError：org/apache/maven/artifact/ant/Dependences造成的任务：java.lang.ClassNotFoundException：org.apache.maven.artifact.ant.Dependencies任务
我尝试过清理渐变缓存，以便重新下载所有依赖项。我也试着清理这个项目。
这没用。
哪些变量会影响等级考试的执行？
对我来说是：
- Gradle本身
- sdk的Java版本
- Internet连接问题
还有什么可以干扰插件版本是否依赖于平台？

BUILD FAILED
我在Linux上也遇到过这个问题，但在OSX上没有。我通过添加找到了解决方案
org.apache.maven：maven ant任务：2.1.3
到我的"testCompile"依赖项。
dependencies {
repositories {
mavenCentral()
}
testCompile 'junit:junit:4.12'
testCompile 'org.apache.maven:maven-ant-tasks:2.1.3'
testCompile 'org.robolectric:robolectric:2.4'
testCompile 'org.mockito:mockito-all:1.9.5'
}
我不知道为什么特立独行的ant任务在linux上不受欢迎。这似乎是一个有效的依赖性的机器人。
选择的答案是正确的，在OSX上将Gradle从2.2.1升级到2.3时也适用。如果不添加testCompile 'org.apache.maven:maven-ant-tasks:2.1.3'的依赖项，那么当Gradle版本为2.3时，Robolectric测试将失败。
同样值得注意的是，我有一个单独的Robolectric测试模块，所以我在Robolectic模块中的build.gradle文件中添加了新的依赖项，而不是我的Android应用程序模块。
刚买了一台新Mac，所以我的旧Mac&新的Mac是并排的，而我配置新的。我用Homebrew构建了我的新Mac，却不知道Gradle 2.3刚刚发布。。。这就是为什么Robolectric测试在我的旧Mac（Gradle 2.2.1）上有效，但在我的新Mac（Grade 2.3）上无效。
