How to a act based on property value, _not_ if set [was: ANT copy
on condition]
I've need to take an action based on the value of a property
(knowing that it's set does me no good). Jan's response to an
earlier question looks like a viable option, but is there an
easier way? For example if I have -
<input validargs="new,existing" addproperty="label_type"
message="Is this ear file based on a new or existing label?"/>
I'd like to do, inside my ant script, as follows -
if(label_type == "new"){
.....
}
else{
.....
}
Thanks in advance.....

And you can do it inside a <script>
Something like
prop = project.getProperty("thePropertyName");
if (prop != null) {
copy = project.createTask("copy");
copy.set....
copy.perform();
}

You can use the <condition> task with <equals> to make the test beforehand:
--------
<antcall target="mytarget"/>
...
<target name="checkLabelType">
<condition property="labelTypeIsNew">
<equals arg1="${label_type}" arg2="new"/>
</condition>
</target>
<target name="mytarget" depends="checkLabelType" if="labelTypeIsNew">
...
</target>
--------

Posted by Wascally Wabbit <wa...@earthling.net>.
You can use the "domatch" tasks from
the http://www.antxtras.info/ package.
For instance:
<do the tasks that set "theproperty".../>
<domatch haltifnomatch="yes|no" property="theproperty">
<equals value="new">
<do the "new" tasks here/>
</equals>
<default>
<do the otherwise tasks here/>
</default>
</domatch>
If you want to match patterns use:
<do the tasks that set the property.../>
<domatch haltifnomatch="yes|no" property="theproperty">
<like value="regular-expression">
</like>
<like value="other-regular-expression">
</like>
</domatch>
