Ant+Ivy快速起步
有了Ivy的帮忙,我们不需要为了一个库依赖管理而舍弃Ant去学那个难搞的Maven了。基本配置步骤如下:
1、copy Ivy插件(见附件)到ant_home/lib下;
2、在项目根目录下新建ivysettings.xml;
3、在项目根目录下新建ivy.xml,内容根据项目需要来;
4、修改你原来的build.xml,如下:
Java代码
增加ivy需要的属性:
<p><property name="publish.version" value="0.1" /> </p><p><property name="ivy.report.todir" value="build" /> </p><p><property name="repository.dir" value="d:/Local_Repository" /> </p><p></p><p>初始化ivy: </p><p><ivy:settings file="ivysettings.xml" /> </p><p></p><p>添加resolve target,用于下载依赖包: </p><p><target name="resolve" description="--> resolve and retrieve dependencies with ivy"> </p><p> <ivy:resolve file="ivy.xml" conf="*" /> </p><p> <ivy:retrieve pattern="${lib.dir}//-." /> </p><p></target> </p><p></p><p>让原来的compile依赖于resolve: </p><p><target name="compile" depends="resolve"</p><p></p><p>添加publish target,这个不是必须的: </p><p><target name="publish" depends="jar" description="publish"> </p><p> <ivy:publish resolver="local" pubrevision="${publish.version}" overwrite="true"> </p><p> <artifacts pattern="dist/." /> </p><p> </ivy:publish> </p><p> <echo message="project ${ant.project.name} released with version ${publish.version}" /> </p><p></target> </p><p></p><p>添加report target用于生产漂亮的依赖报告,当然这个也不是必须的: </p><p><target name="report" depends="resolve" description="--> resolve and retrieve dependencies</p><p> with ivy"> </p><p> <ivy:report /> </p><p></target></p>
增加ivy需要的属性:
<p><property name="publish.version" value="0.1" /> </p><p><property name="ivy.report.todir" value="build" /> </p><p><property name="repository.dir" value="d:/Local_Repository" /> </p>
初始化ivy:
<ivy:settings file="ivysettings.xml" />
添加resolve target,用于下载依赖包:
<p><target name="resolve" description="--> resolve and retrieve dependencies with ivy"> </p><p><ivy:resolve file="ivy.xml" conf="*" /> </p><p><ivy:retrieve pattern="${lib.dir}//-." /> </p><p></target> </p>
让原来的compile依赖于resolve:
<target name="compile" depends="resolve"
添加publish target,这个不是必须的:
<p><target name="publish" depends="jar" description="publish"> </p><p><ivy:publish resolver="local" pubrevision="${publish.version}" overwrite="true"> </p><p><artifacts pattern="dist/." /> </p><p></ivy:publish> </p><p><echo message="project ${ant.project.name} released with version ${publish.version}" /> </p><p></target> </p>
添加report target用于生产漂亮的依赖报告,当然这个也不是必须的:
<p><target name="report" depends="resolve" description="--> resolve and retrieve dependencies </p><p>with ivy"> </p><p><ivy:report /> </p><p></target> </p><p></p>

Over!
至此,你已经为蚂蚁插上了Ivy的翅膀,下面的工作只是锦上添花而已——在Eclipse配置Ivy,这个
工作的作用是把ivy.xml变成classpath的一部分,使得我们只需要维护ivy.xml不需要维护.classpath
文件。
配置步骤:
1、Window->preference->ant->RunTime->Classpath->Ant Home Entries,
右边Add External Jars,添加org.apache.ivy_2.1.0.cr1_20090319213629.jar。
2、安装Ivy插件:Help->Install new software->add,
Name: IvyDE,Location: http://www.apache.org/dist/ant/ivyde/updatesite
安装成功后重启eclipse;
3、重启eclipse后,Window->preference->ivy->settings
Ivy settings path设为d:/workspace/ivysettings.xml(这个值取决于你的环境)
至此,Eclipse的ivy插件配置好了,然后就可以为你的项目classpath添加ivy依赖了:
选中项目->右键 属性->Java Build Path->Libraries->Add Library...->IvyIDE Managed Depend
encies->finish->OK
然后神奇的事情就出现了——虽然你一个jar包也没下载,只是在ivy.xml里面声明了一下,但是你
的项目已经可以编译通过了,就好像那些第三方类库已经在你本地了一样。
