That's a reasonable point. I had a look at what it would take to get
rid of the patternsets completely. It's quite easy for some modules.
For example, for accessibility, we can just replace the "classes"
fileset with:
<fileset id="classes" dir="${hy.build}">
<or>
<present targetdir="${hy.accessibility.src.main.java}" />
<present targetdir="${hy.accessibility.src.main.java}">
<mapper type="regexp"
from="^(.*?)(\$$[^/\\\.]*)?\.class$$"
to="\1.java"/>
</present>
</or>
</fileset>
Which basically says include files if they are also present in
the source directory - typically resource files - or if they are
.class files and have an obviously-named source file in the source
directory[0].
This works for most modules. The present tags are duplicated for
modules with platform source directories.
However, it doesn't work very well for awt, beans, jndi, luni, and
security. Why? Because they have some source files defining two
classes. For instance, java.awt.ContextImpl defined in:
modules/awt/src/main/java/common/java/awt/Component.java
We could hardcode these special case - there are only a few. Or perhaps
we could split them in to distinct source files?
I have some patches ready to make this change but I've not committed
anything.
Personally I think getting rid of the patternsets would be a good idea
since it reduces the coupling - although really the coupling is only
strictly necessary for luni and security.
It is important to note that even if we do something like this, leaving
the catch-all check in the clean target still helps stop problems - if
people forget to add the hardcoded special cases or if we split them
people add new source defining two classes in one file.

Mark.
[0] The simpler '<mapper type="glob" from="*.class" to="*.java">'
doesn't work because it misses inner classes.
