- what is it?

[DevKon <de...@rogers.com>]

I have problem understanding <classpath> 

>From the manual:

////
   <classpath>
      <pathelement path="${classpath}"/>
    </classpath>
///

What is ${classpath} referring to? Also, how do I get to print variables or properties <echo>${classpath}/<echo> prints "${classpath}", how do I get the actual value?

TIA

DevKon,

1) if your example is the one from "using ant" then it's just a snippet 
and there isn't enough context to see what ${classpath} refers to. 
Basically, some variable defined elsewhere is the correct (but not very 
helpful) answer - but ${classpath} itself has no magic value.

2) <echo>${classpath}</echo> prints "${classpath}" if ${classpath} is 
undefined, but prints the value of ${classpath} if it is defined:

<project name="mytest" basedir="." default="demo">

    <property name="definedvariable" value="foobar"/>

    <target name="demo">
        <echo>${definedvariable}</echo>
        <echo>${undefinedvariable}</echo>
    </target>

</project>


H:\>ant
Buildfile: build.xml

demo:
     [echo] foobar
     [echo] ${undefinedvariable}
