例
项目包含以下文件：
├── build.xml├── ivy.xml└── src ├── main │ ├── java │ │ └── org │ │ └── demo │ │└── App.java │ └── resources │ └── log4j.properties └── test └── java └── org └── demo └── AppTest.java
构建运行如下：

常春藤
常春藤的一个非常强大的功能是配置。这些使您可以将依赖项分组在一起。
<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：
配置使用“扩展”功能来模拟Maven“编译”，“运行时”和“测试” Maven范围。
注意每个依赖项上的特殊“ conf”属性。这是从本地到远程的映射。有关ivy如何管理远程Maven模块的更多详细信息，请参见：ivy如何将maven范围映射到ivy配置
build.xml
常春藤配置可以被诸如cachepath（创建ANT路径）和检索（将文件复制到构建中）之类的任务所利用。我还建议使用报告目标，以便您可以查看每种配置中出现了哪些jar（用于管理传递依赖项）

App.java
你好世界记录示例。
package org.demo;import org.slf4j.Logger;import org.slf4j.LoggerFactory;public class App { static final Logger log = LoggerFactory.getLogger(App.class); public static void main( String[] args ) { App a = new App(); a.speak("hello world"); } public void speak(String message) { log.info(message); }}AppTest.java
这是我档案中的一个旧示例。不使用Junit断言。
ackage org.demo;import junit.framework.Test;import junit.framework.TestCase;import junit.framework.TestSuite;public class AppTest extends TestCase{ public AppTest( String testName ) { super( testName ); } public static Test suite() { return new TestSuite( AppTest.class ); } public void testApp() { assertTrue( true ); }}log4j.properties# Set root logger level to DEBUG and its only appender to A1.log4j.rootLogger=DEBUG, A1# A1 is set to be a ConsoleAppender.log4j.appender.A1=org.apache.log4j.ConsoleAppender# A1 uses PatternLayout.log4j.appender.A1.layout=org.apache.log4j.PatternLayoutlog4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
