Custom task with classpath and exclusion

[Blaise Gervais <ge...@gmail.com>]

Hi everyone,

I'm writing one custom Ant Task who create a classpath. This task can also
exlued files from the class path. But I'm unable to excludes files from the
Path because the path t the excluded file is wrong.
Here is my code :

> FileSet exclusions = new FileSet();

System.out.println("Parent : "+classpathFile.getParentFile());

exclusions.setDir(new File(Path.translateFile(classpathFile.getParent())));

exclusions.setProject(getProject());

Path antClassPath = new Path(getProject());

for (InternalClassPathEntry entry : eclipseClassPath.getEntries(entryKinds))
> {

PathElement element = antClassPath.createPathElement();

element.setLocation(new File(classpathFile.getParentFile(),
> entry.path.getPath()));

if ( entry.exclusions!=null && !entry.exclusions.isEmpty() ) {

for (String exclusion : entry.exclusions) {

System.out.println("Exclude :
> "+entry.path.getPath()+File.separatorChar+exclusion);

exclusions.createExcludesFile().setName(entry.path.getPath()+File.separatorChar+exclusion);

}

}

}

System.out.println(antClassPath);

antClassPath.addFileset(exclusions);


And the output :

> Buildfile: C:\Dev\Perso\App\app-builder\build.xml

test:

[eclipseclasspath] Parent : C:\Dev\Perso\App\app-impl\app-manager

[eclipseclasspath] Exclude :

The "Parent" folder correctly point to the project folder and each "Exclude"
are also existing : Parent+File.separator+Exclude give me a path to a real
file.
But the build fail and tell me that the file is not found. In fact she is
not found bacause ANt try to find it from a wrong folder. It will not look
into "C:\...\app-builder\" but into "C:\...\app-impl\app-manager\" (the
"Parent")

Can you help me please ?

Thanks

In a fileset an excludesfile is a text file that contains an exclusion
pattern per line.  I don't think you really want this but
createExclude(),

This is probably a good name for an exclude pattern which is resolved
relative to the fileset's dir.

excludesfiles as opposed to exclude patterns are resolved relative to
the project's basedir, not the dir of the fileset.
