所以，我一直在四处寻找，我的问题还没有找到一个好的答案，这让我抓狂，所以我想我会在这里问，希望我能得到帮助。我正试图用gradle在giraph项目中进行自动化测试。我对grad尔完全是个初学者。为了开始，我将SimpleShortStpathComputation类的测试代码复制到我的项目中，以确保可以启动并运行测试。当我这么做的时候 gradle test ，但是，出现以下错误：

$ gradle test --info
<skipping some output here...>

BUILD FAILED

我使用的是完全标准的项目目录结构，这是我的build.gradle文件：

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    compile files('$GIRAPH_HOME/giraph-core/target/giraph-1.1.0-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar')
    compile files('$GIRAPH_HOME/giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar')
    compile files('$HADOOP_HOME/hadoop-core-0.20.203.0.jar')

    testCompile group: 'junit', name: 'junit', version: '4.+'
    testCompile group: 'org.mockito', name: 'mockito-all', version: '1.9.5'
}

它编译起来没有问题，我作为依赖项包含的jar文件包括它表示noclassdeffounderror的类（根据 jar tf ). 知道我做错了什么吗？提前谢谢。
