[Proposal] Adding @debuglevel to the compile-build.xml

[Thorsten Scherler <th...@apache.org>]

Hi all,

in forrest we run lately into problems with the linkrewriter and jxpath.
I am trying to debug that but I had some problems.

The problem I had in debugging the
org.apache.cocoon.transformation.LinkRewriterTransformer class in
eclipse (3.1) for forrest is that I got:

"Unable to install breakpoint in ... due to missing line number
attributes. Modify compiler options to generate line number attributes.
Reason: Absent line number information"

See 
http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-7304.html for a
similar problem. 

I patched cocoons compile-build.xml like:
Index: compile-build.xml
===================================================================
--- compile-build.xml   (revisión: 291352)
+++ compile-build.xml   (copia de trabajo)
@@ -24,6 +24,7 @@
   <!-- compilation parts used by all targets -->
   <presetdef name="cocoon.javac">
      <javac
+           debuglevel="lines,vars,source"
            debug="${compiler.debug}"
            optimize="${compiler.optimize}"
            deprecation="${compiler.deprecation}"
wich was recommended in the link. 

I compiled cocoon again and then copied the linkrewriter block lib to
the core of forrest and could connect to the class to debug. 

The @debuglevel is only taken into account if the debug="true" so IMO it
is not doing any harm if we add it. On the other hand with this
attribute set we can debug cocoon with eclipse again.

WDYT?
