build.xml中ant脚本条件 [英] build.xml ant script condition

问题描述

我试着在我的build.xml脚本添加一个条件为我的部署过程。基本上，我需要确定remote.host并根据设定的变量值的主机上。

Im trying to add a condition in my build.xml script for my deployment process. I basically need to determine the remote.host and based on the host set a variable value.

 <condition property="my-prop" value="production">
    <based on host=1234>
 </condition>
 <condition property="my-prop" value="development">
    <based on host=5678>
 </condition>

什么想法？的是如何假设是？

any ideas? of how the is suppose to be?

推荐答案

这应该做的伎俩，猜测你将不得不调整基于机器地址或环境或任何一点。我螺旋桨的值设置为基于对主机性能测试指定的值。

This should do the trick, guessing you will have to tweak a bit based on machine addresses or environment or whatever. Sets the value of my-prop to specified value based on test against the host property.

<!-- <property name="host" value="1234"/> -->
<property name="host" value="5678"/>

<target name="test">
    <condition property="my-prop" value="production">
        <equals arg1="1234" arg2="${host}"/>
    </condition>    
    <condition property="my-prop" value="development">
        <equals arg1="5678" arg2="${host}"/>
    </condition>

    <echo>${my-prop}</echo>
</target>
