Chris Douglas commented on MAPREDUCE-1146:
------------------------------------------
bq. When you canceled the patch, it seemed to be because you didn't like the
degree of complexity I placed in the ant script.
Yes. The build scripts are already awkward to maintain, and what little
maintenance occurs happens as in this issue: enough to fix the immediate
problem. I don't think this imposes a high maintenance burden, as the eclipse
build is hardly high-traffic, but I don't think we disagree that the current
patch is an indirect fix. If that's all there is, then fine, but I'd like to be
sure that this does not incur undue technical debt.
bq. I implemented conditional logic in our buildfile to check the platform, and
inject the correct jar dependency into the Eclipse project classpath file if
it's being constructed in a platform which requires this jar.
More precisely, the patch injects XML comment characters into the Eclipse
project classpath file to exclude a non-existent jar. Unless the eclipse-files
target were rewritten to generate- rather than inject paths into- the classpath
file, I agree, it's not clear how to effect what the current patch achieves.
bq. this isn't related to "Eclipse arcana." The requirements imposed by Eclipse
are straightforward: we need to create a classpath file containing a list of
exactly the jars necessary to compile the project.
I suggested the eclipse dev list because this can't be the first time someone
has thought about this issue. Before settling on injecting XML into an eclipse
configuration file using ant properties, it's not unreasonable to ask if
there's a better way.
