java emma 官网_Java 7-Testng，Emma，Cobertura，coverage和JDK 7导致ClassFormatError和VerifyE

我得到了Gradle 1.0M9，Java 7和EMMA 2.1，可以使用此处建议的补丁：使用jvm参数。

详情在这里...[http://marcellodesales.wordpress.com/2012/04/03/running-emma-code-test-coverage-with-java-7-and-gradle-1-0m9/?preview=true&preview_id=179&preview_nonce=261e892908]

运行“等级测试”可得到以下信息：
