Conditional compilation

[ky...@panix.com]

Hi!  I want to be able to invoke 'ant -DDEBUG=1' whenever I want my
project to be compiled with javac's -g flag.  How do I write the build
file for this?  One klunky way would be something like

  <target name="compile" unless="DEBUG>
    <javac debug="off"/>
  </target>

  <target name="compilewithdebug" if="DEBUG>
    <javac debug="on"/>
  </target>

  <target name="dist" depends="compile,compilewithdebug"/>

But that's a lot of machinery for a simple conditional!  (Not to
mention that it is ugly.)  Is this the only way?

Thanks!

kynn

You're bound to get a flood of replies to this:

<property name="build.debug" value="true"/>
<javac debug="${build.debug}">

then run with: ant -Dbuild.debug=false to turn it off.

So yes, there is a vastly better way!
