Subject Re: help to find not replaced variables
Date Wed, 22 Jul 2009 20:28:00 GMT
Actually, I think this solution might be more of what you want. The first
solution I gave you will only tell you that there were parameters that
weren't replaced, but won't tell you which parameters weren't replaced.
Imagine if you had 100 parameters, and you only replaced 99 of them. It
would take you a long time to find that one parameter out of the 100 that
didn't get replaced.

This solution will actually give you the lines that weren't substituted:

*<loadresource property="nonreplaced.lines">*
*   <concat>*
*      <fileset dir="${property.dir}"/>*
*      <filterchain>*
*         <linecontainsregexp>*
*            <regexp pattern="@[\w]+@"/>
         </linecontainsregexp>
      </filterchain>
    </concat>
</loadresource>    *

The property *nonreplaced.lines* will now contain all the lines that weren't
replaced. Thus, it would be much easier to correct the situation. You'd know
which one you were missing.

This could be put into a fail message to fail the build if any lines were
detected:

*<fail messsage="Lines not replaced: ${nonreplaced.lines}">
  <condition>
    <length string="${nonreplaced.lines}" when=greater" count="0"/>
  </condition>
</fail>

*
We (including me) really should start looking more into filterchains and
resources. They're a bit harder to understand than standard ant tasks like
"copy", but they offer a lot of power.
