Subject RE: how to copy/move a file to dynamically generated file name

Or if you want to keep everything in the build.xml (you must have a finite
number of deployEnv values):

<target name="copy"
        depends="set-properties" />
  <copy file="template.xml"
        tofile="${hostname}_${realm}.xml" />
</target>

<target name="set-properties"
        depends="select-deployEnv, fail4-bad-deployEnv,
                 set-properties1, set-properties2" />

<target name="select-deployEnv">
  <condition property="bad-deployEnv">
    <not>
      <or>
        <equals arg1="${deployEnv}" arg2="expected-value1" />
        <equals arg1="${deployEnv}" arg2="expected-value2" />
      </or>
    </not>
  </condition>

  <condition property="use-deployEnv1">
    <equals arg1="${deployEnv}" arg2="expected-value1" />
  </condition>
  <condition property="use-deployEnv2">
    <equals arg1="${deployEnv}" arg2="expected-value2" />
  </condition>
</target>

<target name="fail4-bad-deployEnv"
        if="bad-deployEnv">
  <fail message="Unknown deployEnv: ${deployEnv}" />
</target>

<target name="set-properties1"
        if="use-deployEnv1">
  <property name="hostname" value="host1" />
  <property name="realm"    value="realm1" />
</target>

<target name="set-properties2"
        if="use-deployEnv1">
  <property name="hostname" value="host2" />
  <property name="realm"    value="realm2" />
</target>

it sure it more complicated, but it should work. Alexey's solutions is
better. You might just want to make sure the file actually exist though,
since <property file="" /> will silent not fail when it cannot find the
file. The only thing the solution above as is that everything is in
build.xml, but that's not a requirement for most people. --DD

I think the recommended way is to create separate property files, then:

<property file="${deployEnv}.property" prefix="env"/>
<copy file="template.xml" tofile="${env.hostname}_${env.realm}.xml"/>

Alexey,

I forgot to mention one thing, the environment name used in properties
file (dev in this case) is passed in to ant as -D property deployEnv. So
I tried ${${deployEnv}.hostname}_${${deployEnv}.realm}.xml but that does
not seem to work.
