我试图让一个简单的（？）测试项目有蚂蚁，常春藤和JUnit工作。 其基本思路是，将常春藤下载的junit.jar和Ant将使用它。
需要注意的是JUnit的罐子是在类路径中 ，否则（不classpath中junit任务元素）我看“<类路径>为<junit的>必须包括的junit.jar如果不是在Ant的自己的类路径”。 另外，（junit.framework.TestListener）下面给出的类是在JUnit-4.8.2.jar。
然而，当我尝试ant test上我看到以下内容：
test:
BUILD FAILED
/home/andrew/project/guice/hg/build.xml:33: java.lang.NoClassDefFoundError: junit/framework/TestListener

...
所以我想的东西是错误与我的build.xml？ 什么？
这里是build.xml文件：
<project xmlns:ivy="antlib:org.apache.ivy.ant"
name="java-example" default="dist" basedir=".">

和编译后，对现有的目录结构：
.

更新顺便说一句， ant -lib lib test （明确给予lib目录）的作品。 而且有很多的这种随机的网页搜索结果的处理混乱的描述-但我的印象是，上面的方法是一致的最新文档 （我用蚂蚁1.9） -见点5。所以我想这可能是一个错误 ; 错误 。
例
项目包含以下文件：
├── build.xml
├── ivy.xml
└── src
├── main
│ ├── java
│ │ └── org
│ │ └── demo
│ │ └── App.java
│ └── resources

构建运行如下：

的ivy.xml
常春藤的一个非常强大的功能是配置 。 这允许你组依赖关系在一起。
<ivy-module version="2.0">
<info organisation="com.myspotontheweb" module="demo"/>
<configurations>
<conf name="compile" description="Required to compile application"/>
<conf name="runtime" description="Additional run-time dependencies" extends="compile"/>
<conf name="test" description="Required for test only" extends="runtime"/>
</configurations>
<dependencies>
<!-- compile dependencies -->
<dependency org="org.slf4j" name="slf4j-api" rev="1.7.5" conf="compile->default"/>
<!-- runtime dependencies -->
<dependency org="org.slf4j" name="slf4j-log4j12" rev="1.7.5" conf="runtime->default"/>
<!-- test dependencies -->
<dependency org="junit" name="junit" rev="4.11" conf="test->default"/>
</dependencies>
</ivy-module>
笔记：
- 该配置使用以仿真Maven的“编译”，“运行时间”和“测试”的Maven范围的“延伸”功能。
- 请注意每个依赖特殊的“CONF”属性。 这是从本地到远程的映射。 有关如何远程Maven模块的更多细节由常春藤看管理： 如何行家范围映射到常春藤常春藤配置
build.xml文件
常春藤配置可以通过类似任务中利用cachepath （创建一个ANT路径）和检索 （复制文件到您的构建）。 我也建议使用报告的目标，这样你可以看到这瓶出现在每个配置（有用的管理传递依赖）

注意：
- 有条件的“安装 - 常春藤”的目标会自动安装常春藤。 只是重新运行构建，只需要进行一次。
App.java
你好世界记录的例子。

import org.slf4j.LoggerFactory;
/**

*/
public class App {
static final Logger log = LoggerFactory.getLogger(App.class);

App a = new App();
a.speak("hello world");
}
public void speak(String message) {
log.info(message);
}
}

这是从我的档案旧的例子。 不使用JUnit断言。

*/
public class AppTest

*/
public AppTest( String testName )
{
super( testName );
}
/**
* @return the suite of tests being tested
*/
public static Test suite()
{
return new TestSuite( AppTest.class );
}
/**

*/
public void testApp()
{
assertTrue( true );
}
