conditional logic and user input

[dave_davis]

Hi,

I want to be able to control my build depending on user input.  I've tried the following code but the ifyes and ifno targets never run.  I'm new to ant so am sure I've missed something fundamental but can't see what it is - all help appreciated!

Cheers

Dave

<project name="test" default="myDefault">

        <target name="myDefault">
                <input message="Enter the value" addproperty="result" />
                <condition property="result.is.yes">
                        <equals arg1="Y" arg2="${result}" />
                </condition>
                <condition property="result.is.no">
                        <equals arg1="N" arg2="${result}" />
                </condition>
                <echo message="${result}"/>
                <echo message="${result.is.yes}"/>
                <echo message="${result.is.no}"/>
                <antcall target="ifyes" />
                <antcall target="ifno" />

        </target>

        <target name="ifyes" if="${result.is.yes}">
                <echo message="I am yes" />
        </target>
        <target name="ifno" if="${result.is.no}">
                <echo message="I am no" />
        </target>
</project>

The if attribute takes the name of the property, not its value. These
should be

<target name="ifyes" if="result.is.yes">

and

<target name="ifno" if="result.is.no">

You could also make the logic easier:
<target name="myDefault">
  <input addproperty="result" validargs="Y,N"  .../>
  <antcall target="do${result}"/>
</target>
<target name="doY"> ...
<target name="doN"> ...
