Maybe the xpath PropertyHelper would help you in this case. My version of <subant> (not based on it (yet)) does what I suggested, but not by reusing Projects, because it's also internally using <ant> :-) Rather I have a static Map which tells me what targets I've already run on what buildfiles. Of course it's not always desirable to run a target only exactly once. But IMO, if the buildfiles are well organized, this should be the case. At least for project inter-dependencies. And I can of course always get around this "optimization" by using <ant> instead. Also my <subant> has a "onlyonce" attribute to control this. I found that I can significantly lower my build times with this behaviour. Also the log is more readable. I think I will continue using my own <subant>. But if someone thinks this is a good idea I could write a patch which would add a "onlyonce" attribute to Ant's <subant>. -- knut > I hope I'm not too off base vis-à-vis your question. --DD > > > -----Original Message----- > > From: Knut Wannheden [mailto:[EMAIL PROTECTED] > > Sent: Thursday, August 14, 2003 6:40 AM > > To: [EMAIL PROTECTED] > > Subject: can <subant> reuse Projects? > > > > Hi, > > > > Up until now I've been using my own <subant> like task. > But now that Ant > > 1.6 doesn't seem too distant anymore I'd like to integrate > with <subant>. > > > > There's one thing I'm wondering about: Can <subant> reuse > the same Project > > object corresponding to a buildfile in multiple calls?
