linux 磁盘管理工具

IVY,它是一个管理（记录、跟踪、解析和报告）项目依赖的工具，可与ApacheAnt紧密集成,很多的信息，请参照： http://ant.apache.org/ivy
1.代码可以从这里得到 svn co https://svn.apache.org/repos/asf/ant/ivy/core/trunk ivy
2.确保你的机子上已经安装了ant　（version 1.6.5 or 以上）与jdk1.5,进入$IVY_HOME(checkout svn url的目录)后，运行ant jar ，在$IVY_HOME/build会生成一些jar包，把$IVY_HOME/build/artifact/ivy.jar 和$IVY_HOME/lib/jsch.jar　拷贝到$ANT_HOME/lib(如果是windows %ANT_HOME%/lib)
3.这样就可以在build.xml用 ivy dependency

e.g:
这是个是build.xml
<project name="hello-ivy" default="run" xmlns:ivy="antlib:org.apache.ivy.ant">
<!--引入ivy　dependency -->
<!-- some variables used -->
<property name="lib.dir" value="lib" />
<property name="build.dir" value="build" />
<property name="src.dir" value="src" />

<!-- paths used for compilation and run -->
<path id="lib.path.id">
<fileset dir="${lib.dir}" />
</path>
<path id="run.path.id">
<path refid="lib.path.id" />
<path location="${build.dir}" />
</path>

<!-- =================================
target: resolve 得到所依赖的文件，依赖的文件在ivy.xml下设置
================================= -->
<target name="resolve" description="--> retreive dependencies with ivy">
<ivy:retrieve/>
</target>

<!-- =================================
target: report 导入一些report 信息
================================= -->
<target name="report" depends="resolve" description="--> generates a report of dependencies">
<ivy:report todir="${build.dir}"/>
</target>

<!-- =================================
target: run
================================= -->
<target name="run" depends="resolve" description="--> compile and run the project">
<mkdir dir="${build.dir}" />
<javac srcdir="${src.dir}" destdir="${build.dir}" classpathref="lib.path.id" />
<property name="msg" value="hello ivy !"/>
<java classpathref="run.path.id" classname="example.Hello">
<arg value="-message"/>
<arg value="${msg}"/>
</java>
</target>

<!-- =================================
target: clean
================================= -->
<target name="clean" description="--> clean the project">
<delete includeemptydirs="true">
<fileset dir="${basedir}">
<exclude name="src/**" />
<exclude name="build.xml" />
<exclude name="ivy.xml" />
</fileset>
</delete>
</target>

<!-- =================================
target: clean-cache 删除所有依赖的缓存文件
================================= -->
<target name="clean-cache" description="--> clean the ivy cache">
<ivy:cleancache />
</target>
</project>

这个是ivy.xml

<ivy-module version="1.0">
<info organisation="apache" module="ivyrep-example"/>
<dependencies>
<dependency org="apache" name="commons-lang" rev="2.0"/>
<dependency org="apache" name="commons-cli" rev="1.0"/>
</dependencies>
</ivy-module>
