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 . . .
