如何在IBM J9 JVM上使用JMockit和Gradle？

Question

我使用Gradle（里程碑8a)在IBM J9 JVM的项目上运行JUnit测试，根据“用JMockit运行测试”，这需要将参数-javaagent:jmockit.jar传递给JVM。然而，JMockit并没有注入mocked参数，这导致我的测试以“method（foo）应该没有参数”而失败，测试在Eclipse的HotSpot JVM上运行良好。

我扩展了test任务，以查找JAR并将参数添加到jvmargs中，如下所示：

test {
   doFirst {
     // Don't do this until the task is actually being executed, because 
     // as soon as we call testCompile.find the configuration is resolved and 
     // can't be modified anymore.
     jMockit = project.configurations.testCompile.find {
       it.name.startsWith("jmockit-")
     }
     jvmArgs "-javaagent:${jMockit}"
   }
}

dependencies {
  testCompile 'com.googlecode.jmockit:jmockit:0.999.13'
  testCompile 'junit:junit:4.10'
}

gradle check--debug的输出确认正在使用-javaagent参数：

12:44:14.816 [DEBUG] [org.gradle.process.internal.DefaultExecHandle] Started Gradle Worker 1.

我很确定我已经做了我该做的一切。为什么我的测试无法运行？
