Nope. Same results. I instantiated File3 object in File1. But only =
File3.java was compiled. I also constructed the File1 object in File3, =
and I got a compilation error while File3.java was compiled - saying =
could not resolve symbol File1!=20

Does that help?

I think you need File1.java to do more then just import File3.java.  If
you construct the class File3 in File1 I think you will have the same
results I am having.  Let me know.

Ant only passes those files that need to be compiled and are not in the
exclusion list to javac. I tried out an example based on Nathan's
problem and I got perfect results as expected. My build script is :

<property name=3D"srcDir" value=3D"c:\temp\testingAnt\srcdir" />
<property name=3D"buildDir" value=3D"c:\temp\testingAnt\buildDir" />

<target name=3D"compile" description=3D"clean up" >
    <javac=20
	  srcDir=3D"${srcDir}"=20
	  destdir=3D"${buildDir}"=20
	  classpath=3D"${classpath}"
          debug=3D"off">           =20
      <include name=3D"com/**" />=20
      <exclude name=3D"com/package1/File1.java"/>
      <exclude name=3D"com/package2/File2.java"/>
    </javac>
</target>
=20
<target name=3D"clean" description=3D"clean up" >
        <delete dir=3D"${buildDir}/com" failonerror=3D"false" />       =20
</target>

I ran the above script with a directory structure as follows:

\srcdir
  |--com
  |----package1
  |     |---File1.java (imports File3)
  |     |---File3.java=20
  |----package2
        |---File2.java

Results:  The files File1.java & File2.java never ever get compiled.
Every time I run with target clean or touch File3.java, only the
File3.java gets compiled.

And that is expected behaviour. So Nathan check your directory structure
and script again. Try out the above if you still have doubts.

Java compilers will compile whatever files they need, if they can find
them (which, since these two files live in the same source path as the
other files you're compiling, it will). So if these two are referenced
by
the files you do want to compile, the compiler will go find them and
compile them, regardless of whether they're in the actual list of files
you've handed off to the compiler.
