尝试使用Ant运行TestNG测试时出现“构建失败”错误

Question

在这里，我将testng.xml集成到build.xml文件中。 但是，当我尝试运行build.xml时，出现“ Build failed”错误。 我不知道为什么 如果您有什么想法请给我建议。 另外，请查看我的执行步骤，以使您更好地理解。 如果有任何错误，请告诉我。

执行步骤：

1. 删除bin，docs，jar文件夹（如果已存在）
2. 为bin，docs，jar创建新文件夹
3. 设置外部罐子的类路径。
4. 在设置类路径之前，我将“ testng-6.8.5.jar”放置在lib文件夹中（当前仅使用一个jar文件）
5. 编译源代码并将.class文件复制到bin文件夹中
6. 运行特定的“目标”以从TestNG获取测试报告

在build.xml

下面是我的java代码

package myPack2;
import org.testng.annotations.Test;
import myPack.Test1;
public class TestNGMain {

    @Test
    public void getTest(){
        Test1 test = new Test1();
        System.out.println("Result===========> "+test.division(20, 10));
    }

}

的testng.xml

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

<suite name="AntBasics">
    <test name="order">
        <classes>
            <class name="myPack2.TestNGMain" />
        </classes>
    </test> 
</suite>

Answer 1

该TestNG JAR内没有JCommander文件。 这是TestNG ant发行版的错误。 您可以通过此ZIP http://testng.org/testng-6.0.1.zip使用JAR
