为什么我在ant下的测试用例总是运行两次？

Question

我正在尝试配置使用Ant的webdriver+testNG。这是一个简单的测试用例，启动FF并打开http://www.google.com。但是当我用ant执行build.xml时，测试用例执行了两次！这对我来说是个谜，我怀疑"Ant套件“中有什么问题，我不知道如何禁用it.here是我的代码。

Eclipse控制台输出：

    init:
    compile:
    [javac] D:\Workspace\HelloAnt\build.xml:23: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

testng.xml代码：

<?xml version="1.0" encoding="UTF-8"?>
<suite name="reportng demo" verbose="2">
<test name="test">
        <classes>
            <class name="example.NewTest">

                    <include name="setup"/>

                </methods>
            </class>
        </classes>
    </test>

为什么你有两个目标- run_tests和run？我认为这是跑步的目标才是问题所在。移除目标，看看它是否有效。
