Target dependency
Hi all,
I have couple of questions -
1. Can a target in one project depend on target on another project ?
2. Is there any order in which the sub build is invoked when subant is called ?
For eg. if i invoke
<subant target="">
<fileset dir="." includes="*/build.xml"/>
</subant>
And I have 3 sub directories A,B and C. Which build.xml will be invoked first ?
3. Already I have raised this questions. Any clue ? Is there a way to execute all sub-builds with a single subant call.
For eg.
<subant target="">
<fileset dir="." includes="*/build.xml"/>
</subant>
The above call builds all sub-builds in current directory. I need to handle nested directories(not only the first level but also subsequent levels).
Thanks
Shreedhar

What syntax is that? It looks like some product specific thing (like
SQL Loader or equivalent). If you want to execute a command on the
remote server, something like the exec task may be of more use.
There is also an FTP task for moving files to the remote server.
More information about what you are trying to achieve would help us
narrow down the options. Maybe Ant isn't the appropriate tool for
what you are trying to do.

In a way, yes. You can import that other build file, or you cn use an
ant task as first task in your target that needs to depend on the
other build.

Yes, you can use a <path> instead of a fileset, which is sorted. The
drawback is that you can't use wildcards then. Ant 1.7 will change
that since you will be able to sort filesets - plugging in your own
sorting algorithms if necessary.
For Ant 1.6 you could write your own task to create path of the
fileset sorting them in the order you need.

Depends on your OS and maybe even on your Java VM. The build.xml that
is found first by Ant when it traverses the file system - so the
question is what is the first directory returned by
java.io.File.list(), which doesn't have any globally correct answer.
Most likely it will be in alphabetical order.

I've already answered it:

This requires a higher level application driving the build sequence. The
higher level application could be a custom ant task or a application
embedding ant. That application would sort projects based on some sort of
dependency model. Either way - I think your looking for functionality that
is not inside Ant at this time - however there are projects around that deal
with these problems - e.g. the Ivy Project [1] or the DPML Depot Project [2]
amongst others.
