突然无法从ant运行TestNG测试([testng] Caused by: java.lang.ClassNotFoundException: com.beust.jcommander.ParameterException) [英] Suddenly can't run TestNG tests from ant ([testng] Caused by: java.lang.ClassNotFoundException: com.beust.jcommander.ParameterException)

问题描述

我正在使用 ant 和 TestNG 6.1.1，昨天我的测试工作正常.今天，当我尝试运行测试时，我得到一个 NoClassDefFoundError，涉及 com/beust/jcommander/ParamException.这是输出:

I am using ant and TestNG 6.1.1, and I had my tests working just fine yesterday. Today when I try to run the tests I get a NoClassDefFoundError involving com/beust/jcommander/ParamException. Here is the output:

[copy] Copying 1 file to /Users/djohnson/src/webapp/components/build/tmp
[testng] Exception in thread "main" java.lang.NoClassDefFoundError: com/beust/jcommander/ParameterException
[testng] Caused by: java.lang.ClassNotFoundException: com.beust.jcommander.ParameterException

[testng] The tests failed.

这是我正在使用的 .xml 文件:

Here is the .xml file I'm using:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Single Method Suite">
  <test name="Single Method Test">
    <classes>
      <class name="DhcpTest">
        <methods>
          <exclude name=".*" />
          <include name="setGetEnabledTest" />
        </methods>
      </class>
    </classes>
  </test>
</suite>

我还没有运气就指定了类的完整路径.我检查了类路径，一切似乎都很好，有人对此有任何想法吗?

I've also specified the complete path for the class with no luck. I've checked the classpath and everything seems fine, does anyone have any ideas on this?

推荐答案

如果您使用的是 ant，JCommander 应该在 testng.jar 中，所以我认为您的 testng.jar 文件可能已损坏.

If you're using ant, JCommander should be inside testng.jar, so I'm thinking your testng.jar file might be corrupt.
