我想在两台不同的计算机上执行一个蚂蚁脚本。根据计算机的名称,应执行两个目标之一。以下操作无效:
<project name="import" default="all">
<property environment="env"/>
<target name="staging" if="${env.COMPUTERNAME}='STG'">
<echo>executed on staging</echo>
</target>
<target name="production" if="${env.COMPUTERNAME}='PRD'">
<echo>executed on production</echo>
</target>
<target name="all" depends="staging,production" description="STG or PRD"/>
</project>
据我了解,“ if”只能与属性一起使用,它会检查是否设置了属性。但是,有没有一种方法可以根据属性的值来建立条件?
答案 0 :(得分:0)
我建议编写一个“ init”目标,该目标设置了以后构建步骤所需的任何条件,并且如果某些必需的属性未达到预期的效果,也将使构建失败。
例如:
<target name="all" depends="staging,production,init" />
<target name="staging" if="staging.environment" depends="init">
<echo message="executed on staging" />
</target>
<target name="production" if="production.environment" depends="init">
<echo message="executed on production" />
</target>
<target name="init">
<condition property="staging.environment">
<equals arg1="${env.COMPUTERNAME}" arg2="STG" />
</condition>
<condition property="production.environment">
<equals arg1="${env.COMPUTERNAME}" arg2="PRD" />
</condition>
<fail message="Neither staging nor production environment detected">
<condition>
<not>
<or>
<isset property="staging.environment" />
<isset property="production.environment" />
</or>
</not>
</condition>
</fail>
</target>
