This issue of running targets via <antcall> that have 'depends' set to the
same target(s) has come up a number of times. The usual workaround
suggestion is to have the common dependency(s) set a "<targetname>.done"
property and include an "unless" on it, but this isn't really a very
elegant solution. Mark McMillan has donated a <do> task, which allows you
to run other targets without re-running the common dependency(s) for each
called target. For example:
<target name="common">
<echo message="Running common..."/>
</target>
<target name="doit">
<echo message="Do some tasks..."/>
<do target="t1"/>
<do target="t2"/>
</target>
<target name="t1" depends="common">
<echo message="In t1..."/>
</target>
<target name="t2" depends="common">
<echo message="In t2..."/>
</target>
$ ant
doit:
[echo] Do some tasks...
common:
[echo] Running common...
t1:
[echo] Running t1...
t2:
[echo] Running t2...
I think this would be a useful task. The code is small, straightforward,
and wouldn't be likely to add any significant maintenance problems. Any
objections?
