<project name="name" default="test" basedir=".">

   <!-- Define <testng> task -->

<taskdef resource="testngtasks"> 
      <classpath>

   <path refid="classpath.base" />
   </path>

   <target name="clean" >

   <target name="compile" depends="clean">

   <target name="test" depends="compile">

收到以下错误:
构建失败
问题:无法创建任务或键入 testng
原因:名称未定义.
行动:检查拼写.
行动:检查是否已声明任何自定义任务/类型.
行动:检查任何/声明已经发生.

Following error is being received:
BUILD FAILED
Problem: failed to create task or type testng
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any / declarations have taken place.

它有效，但现在我收到另一个错误:

It worked but now I am receiving another error:

推荐答案

我认为它找不到 jar.

I think it cannot find a jar.

试试

<taskdef resource="testngtasks" classpath="/full/path/to/testng.jar"> 
</taskdef>

或者将 testng.jar 放在 ANT_HOME/lib 中使用:

Or put testng.jar in ANT_HOME/lib and use:

<taskdef resource="testngtasks" classpath="testng.jar"> 
</taskdef>

您应该将 jar 添加到您的 classpath.test

You should add jars to your classpath.test

 <path id="classpath.test">
    <fileset dir="lib">
        <include name="**/*.jar"/>
    </fileset>  
  </path>

com/beust/jcommander/ParameterException 类在哪里定义?

您可以打印类路径以确保其中包含 jar.

You can print classpath to ensure the jar is included in it.

<pathconvert property="classpath.test.prop" refid="classpath.test"/>
<echo>Classpath is ${classpath.test.prop}</echo>

你应该在 testng 任务调用中使用 classpathref 而不是 classpath

you should use classpathref not classpath in your testng task call

<testng outputdir="${testdir}" classpathref="classpath.test"> 
         <xmlfileset dir="${srcdir}" includes="TestNG.xml"/> 
</testng>
