Hi,
or solution via script, i.e.
<project name="bla" default="main" basedir=".">
<!-- // Properties -->
<echo file="y:/props.txt">
key = value
key.1 = value1
bind.i.address = foobar
</echo>
<!-- Properties // -->
<target name="depends">
<script language="ruby">
<![CDATA[
pattern = /bind\.ip\.address/
str = File.read("Y:/props.txt")
$project.setProperty "ok-address-config", "true" if str.match(pattern)
]]>
</script>
<!-- or
<script language="ruby">
<![CDATA[
File.open("Y:/props.txt", "r").each do |line|
$project.setProperty "ok-address-config", "true" if line =~
/bind\.ip\.address/
end
]]>
</script>
-->
</target>
<target name="merge" if="ok-address-config">
<echo>Condition checked > OK ! > proceed ...</echo>
</target>
<target name="main" depends="depends,merge"/>
</project>
Regards, Gilbert

Subject: AW: Verifying if a property is present in a property file
The easiest way is loading the property file ...
<property file="" prefix="tmp"/>
<target name="merge" if="tmp.TheMagicProperty">
...
</target>
Alternatively you could search for the string "TheMagicProperty=" in the file
...
