</project> 

以下错误：
构建失败
问题：无法创建任务或类型TestNG的
原因：这个名字是不确定的。
操作：检查拼写。
操作：检查是否声明了任何自定义任务/类型。
操作：检查是否发生了任何/声明。

它的工作，但现在我收到另一个错误：

Answer 1

，我认为它无法找到一个罐子。

尝试

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

或把testng.jar在ANT_HOME/lib和使用：

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

您应该添加罐子你classpath.test

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

所在类别com/beust/jcommander/ParameterException是界定？

您可以打印类路径以确保该jar包含在其中。

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

，你应该在你的TestNG的任务调用使用classpathref不classpath

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