Class JRAntDecompileTask

  • All Implemented Interfaces:
    Cloneable, org.apache.tools.ant.types.selectors.SelectorContainer
    public class JRAntDecompileTask
extends JRBaseAntTask
    Ant task for batch-generating the source JRXML report design files, from compiled report template files. Works like the built-in javac Ant task.

    This task can take the following arguments:

    • src
    • destdir
    Of these arguments, the src and destdir are required. When this task executes, it will recursively scan the src and destdir looking for compiled report template files and it will recreate the source JRXML file for each of them. This task makes its file creation decision based on timestamp and only input files that have no corresponding file in the target directory or where the destination JRXML file is older than the input file will be processed.
