Re: Problem with Ant javac includes

[Conor MacNeill]

I think you may be misunderstanding what "includes" means here. The 
"includes" attribute is used against the source directory to decide 
which files to include in the compilation. In other words, "includes" 
functions as a filter on the set of files from your srcDir. If you add 
something to that filter which does not exist in the set, it has no 
effect - it's not there to include to start with. "Includes" is not an 
explicit specification of which files are to be compiled.

Nevertheless, I understand the issue you are raising. I'd say the best 
way to catch these sorts of issues is with adequate testing.

Hi all Ant users,
we have been using Ant in our projects for 2+ years now. We have 
recently discovered a potential dangerous error (or we believe it's an 
error at least).

When using Ant to compile our package with an explicit includes 
statement, Ant ignores the fact that the file can't be found. Since we 
are using some reflection to minimize coupling, we need this feature but 
this can be dangerous since parts of the package might be omitted from 
the distribution jar.

 <target name="compile_server" depends="init">
    <javac
       includes="mypackage/ExportService.java,
                 mypackage/RetrieveService.java,
                 separate/package/UpdateProperty.java"       <-- MISSING 
FROM ${source}, build successful
       srcdir="${source}"
       destdir="${classes}"
       debug="on">
       <classpath>
          <pathelement location="${3plib}/servlet/servlet2.3/servlet.jar"/>
          <path refid="cb.depend.class.path"/>
          <path refid="crewlist.depend.class.path"/>
       </classpath>
    </javac>
 </target>


Does anyone have any experience with this?
