What is ANT? This is how the ANT homepage defines its tool:

Apache Ant is a Java-based build tool. In theory, it is kind of like Make, but without Make's wrinkles.

Basics

  • the ANT build file is based on XML
  • the usual name for the build file is
 build.xml
  • invocation - the usual build file needs not be specified explicitly, if it's in the current directory; if not target is specified, the default one is used
 ant [-f <build-file>] [<target>]
  • displaying all the available targets of a build file
 ant [-f <build-file>] -projecthelp

Weka and ANT

  • a build file for Weka is available from Subversion (it has been included in the weka-src.jar since version 3.4.8 and 3.5.3)
  • it is located in the weka directory
  • some targets of interest
    • clean - Removes the build, dist and reports directories; also any class files in the source tree
    • compile - Compile weka and deposit class files in ${path_modifier}/build/classes
    • docs - Make javadocs into {${path_modifier}/doc}}
    • exejar - Create an executable jar file in ${path_modifier}/dist
