<fail> in an <imported> macro outputs wrong





------- Additional Comments From peter.reilly@corvil.com  2004-02-25 17:09 -------
The backtrace is part of the macrodef for two purposes:
1) macrodefs can be difficult to get correct - esp, macrodefs
   calling macrodefs.
2) It is not obvious where to say the location of the error is-
   at the point of call, or within the macro
For example:

<macrodef name="f">
  <sequential>
    <fail>the macro failed</fail>  <!-- (1) -->
  </sequential>
</macrodef>

<f/>   <!-- (2) -->

Should the error location be (1) or (2)

For a proper emulation of a real task, it should (2).

I propose to add a attribute backtraceonerror (default true) to
macrodef control the generation of the backtrace.

3:    <macrodef name="f" backtraceonerror="no">
4:      <sequential>
5:        <fail>A fail message</fail>
6:      </sequential>
7:    </macrodef>
8:    <f/>

Will only:
BUILD FAILED
/home/preilly/learning/ant/backtrace.xml:8: A fail message

and
3:    <macrodef name="f" backtraceonerror="yes">
4:      <sequential>
5:        <fail>A fail message</fail>
6:      </sequential>
7:    </macrodef>
8:    <f/>

will generate:
BUILD FAILED
/home/preilly/learning/ant/backtrace.xml:8: Following error occured while
executing this line
/home/preilly/learning/ant/backtrace.xml:5: A fail message
