I would like to be able to take a macro parameter such as "devel" and
use this information to compute the actual path where the data is stored
(ex \\pca001\mypath). Unfortunately I cannot use properties for these
values because they are immutable once set and I may use each macro more
than once.
How would I take a macro parameter and compute a path in a way that the
macro can be run more than once?
I am using Ant and some Ant macros to encapsulate deploying code in my
organization. In the build.xml for each system I use a single ant task
such as this to deploy the application onto the server.
<deployCorporateWebApp
assemblypath="PetroCanada.Finance.Tales.Website"
target-tier="pcaw2"
target-level="devel"
target-name="talefin"
webconfig="Deploy\Config\website-devel.config"
/>
This is a simplified example of the macro definition.
<macrodef name="deployCorporateWebApp">
<attribute name="target-tier" default="pcaw2" />
<!-- etc -->
<sequential>
<!-- Setup the target.basepath property -->
<condition property="target.basepath"
value="\\pcaw2d1\wwwroot$">
<equals arg1="@{target-tier}"
arg2="pcaw2" />
</condition>
<condition property="target.basepath"
value="\\pcaw2s1\wwwroot$">
<equals arg1="@{target-tier}"
arg2="pcaw2" />
</condition>
<fail unless="target.basepath"
message="Unknown target-level." />
<!-- Compute the rest of the properties. -->
<property name="target.path"
value =
"[EMAIL PROTECTED]" />
<!-- Simplified example of the actualy code -->
<delete dir="${target.path}" />
<copy todir="{target.basepath}"/>
</sequential>
</macrodef>
This does not work because properties are immutable once set.
