Ant: The Definitive Guide

Name

javah

Synopsis

Executes the javah tool, generating Java Native Interface (JNI) headers from one or more Java classes. This task uses the default Java compiler, unless the build.compiler property is set to something else, as explained in the javac task description in Chapter 7.

Attributes

bootclasspath (1.3, 1.4, Path, N)

The bootstrap classpath to use.

bootclasspathref (1.3, 1.4, Reference, N)

Reference to a bootstrap classpath defined elsewhere in the buildfile.

class (1.3, 1.4, String, Y)

A comma-separated list of class names to process.

classpath (1.3, 1.4, Path, N)

The classpath to use.

classpathref (1.3, 1.4, Reference, N)

A reference to a classpath defined elsewhere in the buildfile.

destdir (1.3, 1.4, File, *)

The destination directory for generated files.

force (1.3, 1.4, boolean, N)

If true, the task always writes output files. Defaults to false.

old (1.3, 1.4, boolean, N)

If true, the task uses JDK 1.0-style header files. Defaults to false.

outputfile (1.3, 1.4, File, *)

If specified in place of destdir, the task concatenates all output into this single file.

stubs (1.3, 1.4, boolean, N)

Used when old=true. If true, the task generates C declarations. Defaults to false.

verbose (1.3, 1.4, boolean, N)

If true, the task executes javah in verbose mode. Defaults to false.

Exactly one of either outputfile or destdir is required.
