Basename (Apache Ant API)
Description: declaration: package: org.apache.tools.ant.taskdefs, class: Basename

# Class Basename

java.lang.Object
org.apache.tools.ant.ProjectComponent
org.apache.tools.ant.Task
org.apache.tools.ant.taskdefs.Basename

All Implemented Interfaces:
  `Cloneable`

public class Basename extends Task
Sets a property to the base name of a specified file, optionally minus a suffix. This task can accept the following attributes:

- file
- property
- suffix

The file and property attributes are required. The suffix attribute can be specified either with or without the ".", and the result will be the same (ie., the returned file name will be minus the .suffix).

When this task executes, it will set the specified property to the value of the last element in the specified file. If file is a directory, the basename will be the last directory element. If file is a full-path filename, the basename will be the simple file name. If a suffix is specified, and the specified file ends in that suffix, the basename will be the simple file name without the suffix.

Since:
  Ant 1.5
