(2) linking subprojects in a large project
I do not think (2) is a usecase for import. I think it is better

I think (2) is an important usecase - at least for me.
If you use import, you can call any target you want from any
of the build files, reuse fragments and targets
from other build files, etc.
- cannot span dependencies to 'imported' targets
- cannot access properties and data (i.e. xmlcatalogs, ...) of 'imported' files
Example for missing dependecy feature:
Assuming some subprojects. Each subproject uses a common library to be build before building the subproject.
Calling the subprojects from main project via <ant> activates the build of common lib for each subproject even it is not nessesary.
I would leave inter project depenencies to Gump, or some other tool.
I think use case 2 complicates import with providing enough to really handle what users want out of use case 2.
Let me try to give a use case 2 example
<project name="main" >
<import name="common/build.xml"> <import name="sub1/build.xml">
<import name="sub2/build.xml">
<target name = "compile" depends "sub1-build.compile, sub2-build.compile" />
</project>
<project name ="common>
<target name="compile" />
<project><project name ="sub1">
<target name="compile" depends="common-build.compile,sub2.compile"/>
<project><project name ="sub2-build">
<target name="compile" depends="common.compile"/>
<project>given this case 2 would suggest
ant compile would execute common-compile, sub2-build.compile, sub1-build.compile
even getting this is not enough, you still have to hangle classpath.
ant -f sub2/build.xml will fail unless you add
<import file="../common.build.xml"/>
There is to many complications for import to handle on it's own.
Let another tool handle it.
