需要根据属性值在 ant 脚本中设置路径 (cp) [英] Need to set path (cp) in ant script depending on value of a property

问题描述

我想根据属性的值将路径变量 cp 设置为两个值之一.

I want to set a path variable cp to one of two values depending on the value of an property.

例如以下是我正在努力实现的目标，但我不确定如何使其正常工作......

E.g. the following is what I'm trying to achieve, but I'm not sure about how to get it working properly...

<if>
    <contains string="${jboss.home}" substring="jboss-4.2.3.GA"></contains>
    <then>
        <echo message="Using JBoss 4.2.3 classpath"/>
        <path id="cp"> 
        ...
        </path>
    </then>
    <else>
        <echo message="Using JBoss 4.0.5 classpath"/>
        <path id="cp">
        ...
        </path>
    </else>
</if>

推荐答案

<condition property="usejboss423">
    <contains string="${jboss.home}" substring="jboss-4.2.3.GA"/>
</condition>

<target name="build.jboss.cp" depends="build.jboss.cp.423,build.jboss.cp.405"/>

<target name="build.jboss.cp.423" if="usejboss423">
    <path id="cp">
    ... JBoss 4.2.3 classpath
    </path>
</target>

<target name="build.jboss.cp.405" unless="usejboss423">
    <path id="cp">
    ... JBoss 4.0.5 classpath
    </path>
</target>
