Class SubAnt

  • 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()
        Get the default build file name to use when launching the task.

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

        Returns:
        the name of the default file
