Greetings. New to eclipse and have what has to be a really easy problem to
solve.
I have a project whose file system structure is
[project]/src/AllFiles.java. So...all source files are listed in src, even
though they are different packages.
and then the build path is [project]/classes/
When we compile, we tell the compiler to build the output path based on
the packages, so that the output path might have
[project]/classes/com/blah/beans/
[project]/classes/com/blah/db/
[project]/classes/com/blah/andsoforth/
It's been this way for some time and has worked OK. Now, I want to give
eclipse a shot, but I'm having trouble getting it set up to compile the
files into the respective output paths based on package names. From what
I can tell, it looks like eclipse will only do that if my source folders
are set up by package names, and that's unlikely at this point.
So...is there a way to for me to keep my current source structure, but
still have eclipse build the files into package-specific directories?
Thanks.

Eclipse supports packages that are stored according to JLS2 7.2.1. If
you put all your files into one directory the built-in compiler will not
work and with it most of the coding features.

Thanks for responding, Daniel. So...I've got to create a source directory
structure like so:
/src/com/blah/blah/db
/src/com/blah/blah/beans
and so forth, correct?

Yes. For more info I suggest to read the JLS2 7.2.1 which explains it in
detail.

Hello Dani (and all):
I've got a similar issue, but at the opposite end of the spectrum.
An existing project of significant size is broken down into eclipse
projects, and has the following directory structure:
basedir/
com.myco.myproject1/src/com/myco/mypackage1/*.java
/bin/com/myco/mypackage1/*.class
com.myco.myproject2/src/com/myco/mypackage2/*.java
/bin/com/myco/mypackage2/*.class
com.myco.myproject3/src/com/myco/mypackage3/*.java
/bin/com/myco/mypackage3/*.class
com.myco.myproject4/src/com/myco/mypackage4/*.java
/bin/com/myco/mypackage4/*.class
.. and so on
All the code gets packaged up into a single jar. I believe the team
is currently generating the jar from within eclipse by using the jar
tool and 'checking off' which projects they want included in the jar.
We're using project dependencies in eclipse to build everything. I
guess the original developers felt that this structure kept the
different parts of the project neatly isolated. It makes things much
harder when attempting to jar up a release with ant, though.
JLS3 7.2.1 states that: "As an extremely simple example, all packages
and source and binary code on a system *might* be stored in a single
directory and its subdirectories." This wording seems more like a
potential example, or perhaps a suggestion, than a requirement. Does
the compiler and jar tool expect this layout?
Should I recommend that the team put forth the effort of consolidating
all our projects under a single project directory like this:
basedir/
src/com/myco/mypackage1/*.java
/mypackage2/*.java
/mypackage3/*.java
/mypackage4/*.java
bin/com/myco/mypackage1/*.class
/mypackage2/*.class
/mypackage2/*.class
/mypackage3/*.class
/mypackage4/*.class
It seems more 'standards conforming', but will be a bit of an effort
given the size of the project.
Is there some way to maintain the current directory layout and build the
jar with ant, or should I push for the layout change? Is it worth it?
Thanks.
