NAME

       Debian::Javahelper::Java - Javahelper core library.

SYNOPSIS

	use Debian::Javahelper::Java;

	my @paths = scan_javadoc("/usr/share/doc/libfreemarker-doc/api/");
	print "Freemarker is linked to the following APIs: 
 - ",
	      join("
 - ", @paths), "
";
	my @packnames = find_package_for_existing_files("/bin/ls",
			"/bin/bash");
	print "/bin/ls and /bin/bash are installed via: ",
	      join(", ", @packnames), "
";

DESCRIPTION

       This module is used by various javahelpers to share common code.

       Please note this API is not stable and backwards compatibility is not guaranteed at the current time. Please contact the maintainers if you
       are interested in a stable API.

   Methods
       scan_javadoc($path)
	   Scans the javadoc at $path and returns a list of javadocs it is linked to on the system.

	   Currently it ignores all javadocs linked via other locations than /usr/share/doc and it also makes an assumption that the linked
	   javadoc is in /usr/share/doc/<package>/<dir-or-symlink>. Of course, all Java Policy compliant packages provide their javadoc from
	   there.

	   If /usr/share/doc/<package>/<dir-or-symlink> appears to be a symlink, then it is followed (except for default-jdk-doc).

       find_package_for_existing_files(@files)
	   Consults dpkg(1) to see which packages provides @files and returns this list. All entries in @files must exists (but is not required to
	   be files) and should not be used on a directory.

	   Furthermore all entries must be given with absolute path.

       parse_manifest_fd($fd, $filename)
	   Parses a manifest from $fd, which must be a readable filehandle, and returns a Debian::Javahelper::Manifest.

	   $filename is only used to report parsing errors and should be something that identifies the source of $fd.

       write_manifest_fd($manifest, $fd, $filename)
	   Writes $manifest to the writable filehandle $fd. $manifest must be a Debian::Javahelper::Manifest.

	   $filename is only used to report errors and should be something that identifies $fd.

       write_manifest_section_fd($section, $fd, $filename)
	   Writes $section to the writable filehandle $fd. $section must be a Debian::Javahelper::ManifestSection.

	   $filename is only used to report errors and should be something that identifies $fd.

	   NB: Helper - Not exported.

       slurp_file($file)
	   Reads all lines in $file and returns them as a list.

	   NB: Helper - Not exported.

NAME

       jh_manifest - Adds or/and modifies manifests for jars

SYNOPSIS

       jh_manifest  [debhelperoptions]	[options]  jar1 ... jarN

       jh_manifest  [debhelperoptions]	[options]

DESCRIPTION

       Javahelper tool to add or update manifests in a jar file. It can be used in two modes. If passed jar files, it will only process these jar
       files. Otherwise it will update all jar files in the packages it acts on.

       When processing a package, the debhelper(7) exclude option will make jh_manifest ignore matching jar files.

FILES

       debian/package.manifest (or debian/manifest)
	   This file consist of a list of jar files and values to add to their manifests. Values in this file will take precedence over values in
	   the original manifest (and command line arguments over values in this file).

	   It is allowed to list a link in this file instead of an actual jar file, provided that the link can be resolved when jh_manifest
	   processes it.

	   If a jar file is listed here cannot be found, jh_manifest will print a warning, unless the jar file has been excluded.

	   As of javahelper >= 0.32, you may add comments in this file. If the line starts with a "#" it is completely ignored.

	   This file is ignored if jh_manifest is passed jar files via command line.

OPTIONS

       -c classpath, --classpath=classpath
	   Sets the Class-Path attribute of all processed jar files to classpath.

	   If not passed, then the CLASSPATH environment variable will be used in the given jar file do not have a Class-Path attribute.

       -m class, --main=class
	   Sets the Main-Class attribute to class in all processed jar files.

       -o options, --javaopts=options
	   Sets the Debian-Java-Parameters to options in all processed jar files. This attribute is used by jarwrapper to start java with extra
	   options (e.g. to make more memory available).

       -j /path/to/java/home, --java-home=/path/to/java/home
	   Sets the Debian-Java-Home attribute to /path/to/java/home in all processed jars. This attribute is used by jarwrapper to determine
	   which JVM to use.

EXAMPLES

       An example debian/manifest file:

	# use the symlink so we do not have to update with the next upstream release.
	usr/share/java/my.jar:
	 Class-Path: dep1.jar dep2.jar
	 Main-Class: some.awesome.Class
	usr/share/java/dep2.jar:
	 Class-Path: dep1.jar
