Hi,

To figure out which classes are out-of-date, the javac=20 task assumes that the directory structure under the = source=20 directory matches the package hierarchy of your classes. So, = if you=20 have a class com.foo.SomeClass, the source file needs to be at=20 <srcdir>/com/foo/SomeClass.java. For a source=20 file that isn't in the correct relative position under the source dir, = ant uses=20 the wrong path to look for the class file under the destination=20 directory. Since ant doesn't find the class file there, it decides = that=20 the source file needs to be compiled.

Subject: Re: dependencies in=20 Ant?

I was just about to post a question in the = opposite=20 direction. I have all my files listed in an external file named=20 'javafiles.dat'. When I run ant, all my java files are = re-compiled when=20 not one of them has changed. My target looks like this:=20

    <target name=3D"compile">=20
        <javac = srcdir=3D".:${src.dir}"=20
            = includesfile=3D"javafiles.dat"=20
            = destdir=3D"${build.classes.dir}"=20
            = optimize=3D"on">=20
            = <classpath>=20 =
           &nb= sp;   =20 <pathelement path=3D"${classpath}"/>=20 =
           &nb= sp;   =20 <pathelement path=3D"${build.classpath}"/>=20
            = </classpath>=20
            = <include name=3D"*.java" if=3D"development"/>=20
        </javac>=20

<copydir = src=3D"${src.dir}"=20 =
           &nb= sp;    =20 dest=3D"${build.classes.dir}"=20 =
           &nb= sp;    =20 includes=3D"${cws.packageprefix}/common/**/*.properties"=20
        /> =
   =20 </target>=20

Is my use of 'includesfile' telling the javac to recompile = everytime?=20

The problem gets worse when I run 'ant compile' followed by 'ant=20 jarall'. 'jarall' depends on 'compile' and everything is = compiled again!=20

Any suggestions?
Dan
