I want to specify no -g flags to javac
Hi.
Based on the boolean "debug" attribute of the javac task, ant will
specifiy either "-g" or "-g:none" to javac. However -g:none is actually
not the same as not specifying "-g" at all to javac, as for javac.exe of
JDK1.3 and JDK1.4 AFAIK. I happen to want to do a build with no -g
flags at all.
As of JDK1.3 and 1.4:
-g:none will produce no debugging information at all, and makes trouble
shooting very hard -- i.e. you won't be able to get an informative stack
dump.
No -g flags is an alias to -g:source,lines and is helpful for trouble
shooting, without revealing the variable information. We want to use
this for production build.
-g is an alias to -g:source,lines,vars and is helpful for use with a
debugger. This is OK for a development phase build.
My chances seems to be:
(1) Change the source to alter the behaviour of debug="false", but that
isn't very nice. I don't want to make a branch.
(2) Make an enhancement request, however it seems that the javac task is
designed to define a common set of options that can be applied to all
supported compilers, so making compiler dependend flags specifiable
would probably be against the current design policy.
Maybe I will have to choose (1) for the present.
Are there any better way to address this?

There is. A 'debuglevel' attribute was added to the <javac> task, to give
fine-grained control over this. You'll need to use the Ant 1.5alpha in CVS.

Thank you. Just what I wanted.
I will switch to 1.5 when its ready to go.

1.5alpha's <javac> has a new attribute, 'debuglevel' -- so you can now do:
debug="on"
debuglevel="source,lines"
(Of course, you probably wouldn't want to hard-code in the debug and
debuglevel value, but reference properties instead, so you can switch
their values according to what type of build you're running.)
