echo - How in Ant output values of properties?

Question

In Ant exits task Echo:

<echo message="Hello, world"/>

But it seems useless. I need to check values in ant file. E.g.

 <property file="${user.home}/build.properties"/>
 <echo message="${file}" />

but I receive only:

 [echo] ${file}

How I can have Ant display value of file?

Answer 1

This statement:

<property file="${user.home}/build.properties"/>

Reads a property file(i.e. all properties in that file), and does not set the property named file.

This would be correct. You first set a property and then echo it:

<property name="file" value="${user.home}/build.properties"/>
<echo message="${file}" />
