Class SubAnt

java.lang.Object
All Implemented Interfaces:
java.lang.Cloneable

public class SubAnt
extends Task
Calls a given target for all defined sub-builds. This is an extension of ant for bulk project execution.

Use with directories

subant can be used with directory sets to execute a build from different directories. 2 different options are offered

  • run the same build file /somepath/otherpath/mybuild.xml with different base directories use the genericantfile attribute
  • if you want to run directory1/build.xml, directory2/build.xml, .... use the antfile attribute. The base directory does not get set by the subant task in this case, because you can specify it in each build file.
Since:
Ant1.6

    • getDefaultBuildFile

      protected java.lang.String getDefaultBuildFile()

      This function may be overridden by providers of custom ProjectHelper so they can implement easily their sub launcher.

      Returns:
      the name of the default file
