Actually, I know that Borland's StarTeam has this 'sharing'
functionality (and possibly even ClearCase, but don't quote me on that).
We use this sharing functionality quite a bit to help maintain a
project's third-party dependencies. For example, have a look at the
following tree:
- root
- tps
- junit
- 3.8
- docs
- src.jar
- junit.jar
- httpunit
- 1.5.4
- docs
- src.jar
- httpunit.jar
- webtest_one
- src ...
- lib
- junit.jar -> /root/tps/junit/3.8/junit.jar
- httpunit.jar -> /root/tps/httpunit/1.5.4/httpunit.jar
- webtest_two
- src ...
- lib
- junit.jar -> /root/tps/junit/3.8/junit.jar
- httpunit.jar -> /root/tps/httpunit/1.5.4/httpunit.jar
This gives us several things:
- the flexability to have a single point of storage for all our
3-party-software (giving us the libs together with it's source and docs)
- each project has a library directory, showing/storing all the tps it
depends on
- our build scripts can now be made more generic:
- step one: add all jars in project lib dir to classpath ...
Unfortunatly, Subversion can't do this for us (it's not a blocking issue
for us, but it definatly would be nice). Once Subversion changes
svn:external to be able to use a single file as opposed to a single
directory, I'll be quite happy (but not as happy as I'll be when they
introduce locking ... ;-) ).
