| Only deleting an empty directory (-tree) | Only deleting an empty directory (-tree) 2005-05-30 - By Antoine Levy-Lambert
Hello Juergen,
I would develop a custom selector (read the important section concepts and
types of ant) which selects empty directories.
read this :
http://ant.apache.org/manual/CoreTypes/custom-programming.html#customselectors
http://ant.apache.org/manual/CoreTypes/selectors.html#customselect
http://ant.apache.org/manual/CoreTypes/selectors-program.html
it might even be possible to define your custom selector in the build file
using a scripting langage and the <scriptdef/> task.
Possible solution :
from
example of use of java script in a build file :
http://marc.theaimsgroup.com/?l=ant-dev&m=107693336832222&w=2
project name="test">
<script language="beanshell">
import org.apache.tools.ant.types.selectors.FileSelector;
import org.apache.tools.ant.BuildException;
import java.io.File;
public class EmptyDirSelector extends DataType implements FileSelector
{
boolean isSelected(File basedir, String filename, File file)
throws BuildException {
if (!file.isDirectory()) {
return false;
}
String[] aaa = file.list();
if (aaa != null) {
if (aaa.length == 0) {
return true;
}
}
return false;
}
}
project.addDataTypeDefinition("emptydirselector",
EmptyDirSelector.class);
</script>
<mkdir dir="d:/test1/test2/test3/test4"/>
<mkdir dir="d:/test1/test2/test3/test5"/>
<echo file="d:/test1/test2/test3/test5/test5.txt">
bonjour
</echo>
<delete>
<dirset dir="d:/test1">
<emptydirselector/>
</dirset>
</delete>
</project>
but :
deleteemptydir.xml:2: org.apache.bsf.BSFException: BeanShell script error:
Sourced file: inline eva
luation of: `` import
org.apache.tools.ant.types.selectors.FileSelector; import or . . . ''

of: `` import org.apache.to
ols.ant.types.selectors.FileSelector; import or . . . '' : DataType

Peter, any idea ?
