public class JRAntCompileTask
extends JRBaseAntTask

Ant task for batch-compiling XML report design files. Works like the built-in javac Ant task.

This task can take the following arguments:

• src
• destdir
• compiler
• classpath
• tempdir
• keepjava
• xmlvalidation

Of these arguments, the src and destdir are required. When this task executes, it will recursively scan the src and destdir looking for XML report design files to compile. This task makes its compile decision based on timestamp and only XML files that have no corresponding .jasper file or where the compiled report design file is older than the XML file will be compiled.

JRAntCompileTask

public JRAntCompileTask()

Method Detail

setSrcdir

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

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

Parameters:

srcdir - source path

createSrc

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

Adds a path for source compilation.

Returns:

source path

setDestdir

public void setDestdir(File destdir)

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

Parameters:

destdir - destination directory

setTempdir

public void setTempdir(File tempdir)

Sets the temporary working directory into which to store the temporary files generated during XML report design file compilation. This is only used by the Java bytecode report compilers that need to have the Java source files stored on disk in order to compile them.

If not set, the temporary working directory will be the current working directory, as specified by the user.dir system property.

Parameters:

tempdir - temporary working directory

setKeepjava

public void setKeepjava(boolean keepjava)

Sets a boolean flag that will instruct the Java bytecode report compilers to avoid deletion of the Java source files generated in the temporary working directory during report generation. This is useful when debugging.

Parameters:

keepjava - flag for preventing the deletion of generated Java source files

setCompiler

public void setCompiler(String compiler)

Sets the name of the report compiler class to use when compiling the XML report design files.

The specified class should be an implementation of the JRCompiler interface. When specified, this value will temporarily override the value of the jasper.reports.compiler.class system property.

Parameters:

compiler - report compiler class name

createClasspath

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

Adds a path to the classpath.

Returns:

classpath to use when compiling the report associated Java expressions class

setXmlvalidation

public void setXmlvalidation(boolean xmlvalidation)

Instructs the XML parser to validate the XML report design file during compilation.

Parameters:

xmlvalidation - flag for enabling/disabling the validation feature of the XML parser

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 compiled.

Throws:

org.apache.tools.ant.BuildException

scanDir

protected void scanDir(File srcdir,
           File destdir,
           String[] files)

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

Parameters:

srcdir - source directory

destdir - destination directory

files - included file names

compile

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

Performs the compilation of the selected report design files.

Throws:

org.apache.tools.ant.BuildException
