using snapshots

[Randy Xu <r...@post.harvard.edu>]

So in my multiproject, app-jms depends on app-lib.  I'm trying to figure 
out right now how SNAPSHOT works.

So I:
    1) set <currentVersion>2.1-SNAPSHOT</currentVersion> in top-level 
project
    2) In app-jms I list app-lib as a dependency:

<dependency>
  <groupId>com.micom.vangough</groupId>
  <artifactId>app-lib</artifactId>
  <version>${pom.currentVersion}</version>
  <type>jar</type>
</dependency>

    3) I run 'multiproject:install-snapshot', which gets the following 
output.  Later on, I get a compile error (jms can't find a constant in 
lib, which could be due to a stale jar).  I do not get this error when I 
just run 'multiproject:install'.   I have several questions.  Why does 
it install _both_ app-lib-2.1-SNAPSHOT.jar _and_ 
app-lib-20050111.163717.jar?  Why does app-jms go looking for 
app-lib-2.1-SNAPSHOT.jar - shouldn't it go looking for 
app-lib-20050111.163717.jar?  Isn't that the point of the snapshot 
feature?  And most importantly - what am I doing wrong?  The behavior I 
would like is for app-jms to recompile if app-lib has changed.  I was 
told snapshots were the way to enforce this behavior.
