help with uptodate and hibernate doclet

[Dimitris Mouchritsas <dm...@gmail.com>]

Hi folks, I'm trying to create a condition task so as not to run a
hibernatedoclet target.
The problem is the target does not produce .hbm.xml files for all the
classes. So
for example if we have 3 classes in the src dir say, User.java, Account.java,
Login.java
the resulting files in the build dir might look like:
User.class
User.hbm.xml
Account.class
Account.hbm.xml
Login.class

So not all classes have a hibernate configuration file. My problem is how
can I use uptodate
to check these? I've tried this:
<uptodate>
  <srcfiles dir="${src.dir}">
    <include name="**/mypackage/domain/**/*.java" />
  </srcfiles>

  <chainedmapper>
    <globmapper from="*" to="${domain.build.dir}" />
    <compositemapper>
      <globmapper from="*.java" to="*.class" />
      <globmapper from=".java" to="*.hbm.xml" />
    </compositemapper>
  </chainedmapper>
</uptodate>

But I guess this mapper needs every class to have a corresponding .hbm.xml

The problem with uptodate is that it can only have a single "target"
file to check against. Look at the AntContrib's <outofdate> task.

The <outofdate> task can take more than a single target, and (as an
added bonus), it can define the tasks to run if an outofdate condition
is detected. No more setting a property then having a task check that
property before it executes. Unless, you want to do that. The
<outofdate> task can also set a property if an <outofdate> condition
is detected.

See <http://ant-contrib.sourceforge.net/tasks/tasks/outofdate.html>.

I could imagine a trick here. after running hibernate, you copy 
**/*.class to a separate location. Then, after compiling your source, 
you want compare the base *.java to the build/hibernate/**/*.class. this 
will trigger hibernate if any class has changed.

Some other options
  -restrict the include list to everything that generates a hibernate 
file. if they are all in one package, or all have a specific name, life 
is much easier.

-move to JPA annotations+hibernate. This works pretty well in the java5+ 
world; I prefer it to hibernate in many ways.
