Ant Filesets

In Ant, a fileset is a collection of files or directories that can be used as input for various Ant tasks. A fileset can include files and directories based on patterns and criteria such as file name, file size, file date, and file permissions. Here's an example of an Ant fileset:

php
Copy code
<fileset dir="src">
  <include name="**/*.java"/>
  <exclude name="**/*Test.java"/>
</fileset>

In this example, the fileset includes all Java source files in the "src" directory and its subdirectories, except for files with names ending in "Test.java". The include element specifies which files to include based on a pattern, and the exclude element specifies which files to exclude based on a pattern.

Filesets can be used as input for various Ant tasks that operate on files, such as copying, deleting, archiving, and compiling. For example, the javac task can use a fileset to specify which Java source files to compile:

php
Copy code
<javac srcdir="src">
  <src>
    <fileset dir="src">
      <include name="**/*.java"/>
      <exclude name="**/*Test.java"/>
    </fileset>
  </src>
  <destdir="build/classes"/>
</javac>

In this example, the src element includes a fileset that specifies which Java source files to compile. The javac task compiles the Java source files located in the "src" directory and its subdirectories, except for files with names ending in "Test.java", and places the compiled class files in the "build/classes" directory.

Filesets provide a flexible and powerful way to select files and directories for use in Ant build processes, making it easy to create complex and customizable build workflows.
