Question

Is there any ways to do strings concatination in a `build.xml file?

Concretely, suppose I have a build file that has this block:

  <target name="test1" depends="build">
            <property name ="fname1"/>
            <property name ="fname2"/>
            <echo message=<fname1 CONCAT fname2>/>            
            ...            
    </target>

I’d like to concatenate fname1 and fname2 .

I tried <echo message = "${fname1}" + "${fname2}" but it doesn’t seem to work

Answer 1

You can just do:

<echo message="${fname1}${fname2}"/> 

or

<echo>${fname1}${fname2}</echo>
