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.

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()
                throws org.apache.tools.ant.BuildException

Scans the source directories looking for source files to be decompiled.

Throws:

org.apache.tools.ant.BuildException

scanDir

protected void scanDir(java.io.File srcdir,
                       java.io.File destdir,
                       java.lang.String[] files)

Scans the directory looking for source files to be decompiled. The results are returned in the instance variable reportFilesMap.

Parameters:

srcdir - source directory

destdir - destination directory

files - included file names

decompile
