Summary: Build target specification on command line can be
enhanced
Product: Ant
Version: 1.7.1
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: enhancement
Priority: P2
Component: Core
AssignedTo: notifications@ant.apache.org
ReportedBy: [EMAIL PROTECTED]
Consider the following:
<target name="a"/>
<target name="b" depends="a"/>
<target name="c" depends="a"/>
If one runs targets "b" and "c" from the command line, the target "a" will run
twice:
1. a
2. b
3. a
4. c
Granted, target "a" may be "smart" and skip most of its processing if it
discovers that it has already run. However, even that creates some overhead and
additional console or log output and requires it to be made smart. I haven't
found a way around this except by creating my own shell for ant that creates
new targets dynamically and then runs those. In my example, running "b+c"
instead of "b c" would result in "a b c" instead of "a b a c" execution.
I believe something like this may be useful for general public.
