Computed ids not visible in sub projects?

[Fei Sha <Fe...@prism.uvsq.fr>]

Hi, all
	I have a build file like this:

----------------------------------------------------

<project name="x" default="x">

	<property name="cpid" value="classpath_id" />
	
	<path id="${cpid}">
		<pathelement location="."/>
	</path>

	<target name="x">		
		<antcall
			target="y"
			inheritrefs="true" >
		</antcall>
	</target>
	
	<target name="y">		
		<java classname="test">
			<classpath refid="${cpid}" />		
		</java>
	</target>
	
</project>

-----------------------------------------------------

E:\exmlmedia\qa>ant -f x.xml
Buildfile: x.xml

x:

y:
      [java] Reference classpath_id not found.

BUILD SUCCESSFUL
Total time: 3 seconds

The "classpath_id" is not visible in the sub project.
If I hard code the name as:

	<path id="classpath_id">
		<pathelement location="."/>
	</path>

Then it works fine. Is this intended behavior?

Another thing, when u want to see the value of a variable, u just echo ${v}
anyway similar to see what an id refers to?

Thanks!

Fei Sha

In a way, yes.  Properties are not expanded in the id attribute, so
your path has the literal id ${cpid}.

By using a helper property and <property>'s refid attribute.
