回答by Andreas Dolk
<If>
is based on <condition>
and supports (that's my understanding) the same nested elements (conditions).
<If>
基于<condition>
并支持(这是我的理解)相同的嵌套元素(条件)。
Give this a try:
试试这个:
<if>
<or>
<equals arg1="${var}" arg2="one"/>
<equals arg1="${var}" arg2="two"/>
<equals arg1="${var}" arg2="three"/>
<equals arg1="${var}" arg2="four"/>
</or>
<then>
<echo message="basic dir: ${var}"/>
<copy todir="../direct" verbose="yes" failonerror="no" overwrite="yes">
<fileset dir="${var}">
<include name="**"/>
</fileset>
</copy>
</then>
</if>
