http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24411 odd presetdef behavior with "additive" task parameters like javac srcdir Summary: odd presetdef behavior with "additive" task parameters like javac srcdir Product: Ant Version: 1.6Beta Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] If you use presetdef to create a new task definition, and you supply a default value to a "cumulative" parameter like javac's "srcdir", users of that new definition cannot override that default value, they can only add to it. I find this behavior surprising, and I feel that it seriously limits the usefulness of "presetdef". Many tasks have cumulative parameters like this, e.g.: javac: srcdir, *classpath, extdirs, ... javadoc: sourcepath, packagenames, ... jar: includes, excludes, ... I suspect that users of presetdef will find it much more useful if default values of these cumulative parameters can be overridden, not just supplemented. BTW, aside from this nit, "presetdef" is a wonderful addition to Ant. THanks!
