Maven JUnit和TestNG一起运行返回“；分叉的VM在没有恰当地说再见的情况下终止。VM崩溃或System.exit被调用；

尝试在Maven项目中同时运行JUnit测试和TestNG测试套件

当我运行“mvn clean install”或“mvn clean test”时，JUnit测试被正确执行，但是TestNG测试没有被启动并返回以下错误

Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test failed: The forked VM terminated without properly saying goodbye. VM crash or System.exit called?

另外，（不确定是否有帮助），我的TESTNG.XML非常简单

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd" >

<suite name="SeleniumSuite">    
   <test name="testAll">
      <classes>
         <class name="Runner.runCucumber"/>
      </classes>
   </test>
</suite>

某些代码正在调用系统。退出。您的

Runner.runcumber

类中有什么？您还可以在

系统中放置断点。退出
并查看是谁调用它。
