    public class JRAntDecompileTask

extends org.apache.tools.ant.taskdefs.MatchingTask

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.

Constructor Detail

### JRAntDecompileTask

    public JRAntDecompileTask()

Method Detail

### setSrcdir

    public void setSrcdir(org.apache.tools.ant.types.Path srcdir)

  Sets the source directories to find the compiled report design files.

  Parameters:
    `srcdir` - source path

### createSrc

    public org.apache.tools.ant.types.Path createSrc()

  Adds a path for decompilation source.

  Returns:
    source path

### setDestdir

    public void setDestdir(java.io.File destdir)

  Sets the destination directory into which the report design files should be decompilated.

  Parameters:
    `destdir` - destination directory

### createClasspath

    public org.apache.tools.ant.types.Path createClasspath()

  Adds a path to the classpath.

  Returns:
    classpath to use when decompiling the report

### execute

    public void execute()
                 throws org.apache.tools.ant.BuildException

  Executes the task.

  Overrides:
    `execute` in class `org.apache.tools.ant.Task`
  Throws:
    `org.apache.tools.ant.BuildException`

### checkParameters

    protected void checkParameters()
                            throws org.apache.tools.ant.BuildException

  Checks that all required attributes have been set and that the supplied values are valid.

  Throws:
    `org.apache.tools.ant.BuildException`

### scanSrc

    protected void scanSrc()
