尝试在Maven项目中一起运行JUnit Tests和TestNG Tests Suite。

当我运行“ mvn clean install”或“ mvn clean test”时，JUnit测试正在正确执行，但是TestNG测试未启动，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?

此外，（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>
