Take a look at the <available> task. To create an if-then type of
statement, add a dependency to your task that runs a task that tests
the condition, and have that set a property. Then have your original
task depend upon that property:
<target name="my-target-test">
<available property="folder-exists"
file="${folder.name}"/>
</target>
<target name="my-target"
if="folder-exists"
depends="my-target-test>
<...>
</target>
Target "my-target" will be executed, but first the dependency target
"my-target-test" will be executed. If the folder exists, it will set
the "folder-exists" property. Now, Ant goes back to the "my-target"
task and checks the dependency. If "folder-exists" is set, "my-target"
will be executed. Otherwise, it won't.
Another option is to use the AntContrib <if> task. This is a bit
easier to follow, but you now depend upon installing the AntContrib
library.
