Question

I am getting an error when I try to build my project using ant. Here is the build file:

<?xml version="1.0" encoding="UTF-8"?>

</project>

And here is the ant build log (error at the bottom):

Unresolvable reference ${lib.classpath} might be a misuse of property expansion syntax.

BUILD FAILED (total time: 0 seconds)

What is causing this to happen? I don’t see anything wrong with how I have my paths setup.

Answer 1

You defined paths with reference ids lib.classpath and server.classpath, but then when you refer to them:

<path id="mf.classpath">
    <path refid="${lib.classpath}"/>
    <path refid="${server.classpath}"/>
</path>

You are treating them as a properties, which you haven’t defined. You probably meant:

<path id="mf.classpath">
    <path refid="lib.classpath"/>
    <path refid="server.classpath"/>
</path>
