grails ant 任务，设置不同的环境 [英] grails ant task, set different envrionment

问题描述

尝试创建一个 grails ant 任务，除了用于战争任务的 prod 之外，还有其他环境.

Trying to create a grails ant task that has other environments besides prod for the war task.

我试过了

<target name="war" depends="-init-grails" description="--> Creates a WAR of a Grails application">
        <grails script="War" args="grails.env=${env} ${war.filename}"/>
</target>

和

<target name="war" depends="-init-grails" description="--> Creates a WAR of a Grails application">
        <grails script="War" args="-Dgrails.env=${env} ${war.filename}"/>
</target>

这两个都不起作用，总是只运行生产环境.请注意，我还对 ${env} 进行了硬编码，因此并不是缺少它

Neither of these two work and always just run the production env. Note that I've also hard coded ${env} so it's not that it's missing

推荐答案

我为此使用了一个宏定义:

I use a macrodef for this:

<property environment='env'/>

<property name='grails.home' value='${env.GRAILS_HOME}' />

<condition property='grails' value='grails.bat'>
   <os family='windows'/>
</condition>
<property name='grails' value='grails' />

<macrodef name='grails'>
   <attribute name='action' />
   <attribute name='environment' default='dev' />
   <element name='preargs' optional='true' />
   <element name='args' optional='true' />
   <sequential>
      <exec executable='${grails}' failonerror='true'>
         <preargs />
         <arg value='@{environment}'/>
         <arg value='@{action}'/>
         <args />
      </exec>
   </sequential>
</macrodef>

您可以执行简单的命令:

You can execute simple commands:

<grails action='clean' />

或更复杂的任务，比如你的战争任务:

or more complex ones like your war task:

<grails action='war' environment='${env}'>
   <args>
      <arg value="${war.filename}" />
   </args>
</grails>
