JPACKAGE(1) JDK Commands JPACKAGE(1)

jpackage - tool for packaging self-contained Java applications.

jpackage [options]

Command-line options separated by spaces. See jpackage Options.

The jpackage tool will take as input a Java application and a Java run-time image, and produce a Java application image that includes all the necessary dependencies. It will be able to produce a native package in a platform-specific format, such as an exe on Windows or a dmg on macOS. Each format must be built on the platform it runs on, there is no cross-platform support. The tool will have options that allow packaged applications to be customized in various ways.

@filename
Read options from a file.

This option can be used multiple times.

The type of package to create

Valid values are: {"app-image", "exe", "msi", "rpm", "deb", "pkg", "dmg"}

If this option is not specified a platform dependent default type will be created.

Version of the application and/or package
Copyright for the application
Description of the application
Print the usage text with a list and description of each valid option for the current platform to the output stream, and exit.
Path of the icon of the application package (absolute path or relative to the current directory)
Name of the application and/or package
Path where generated output file is placed

Defaults to the current working directory. (absolute path or relative to the current directory).

Path of a new or empty directory used to create temporary files (absolute path or relative to the current directory)

If specified, the temp dir will not be removed upon the task completion and must be removed manually.

If not specified, a temporary directory will be created and removed upon the task completion.

Vendor of the application
Enables verbose output.
Print the product version to the output stream and exit.

A comma (",") separated list of modules to add

This module list, along with the main module (if specified) will be passed to jlink as the --add-module argument. If not specified, either just the main module (if --module is specified), or the default set of modules (if --main-jar is specified) are used.

This option can be used multiple times.

A File.pathSeparator separated list of paths

Each path is either a directory of modules or the path to a modular jar, and is absolute or relative to the current directory.

This option can be used multiple times.

A space separated list of options to pass to jlink

If not specified, defaults to "--strip-native-commands --strip-debug --no-man-pages --no-header-files"

This option can be used multiple times.

Path of the predefined runtime image that will be copied into the application image (absolute path or relative to the current directory)

If --runtime-image is not specified, jpackage will run jlink to create the runtime image using options specified by --jlink-options.

Path of the input directory that contains the files to be packaged (absolute path or relative to the current directory)

All files in the input directory will be packaged into the application image.

Name of launcher, and a path to a Properties file that contains a list of key, value pairs (absolute path or relative to the current directory)

The keys "module", "main-jar", "main-class", "arguments", "java-options", "app-version", "icon", "linux-app-category", "linux-app-release", and "win-console" can be used.

These options are added to, or used to overwrite, the original command line options to build an additional alternative launcher. The main application launcher will be built from the command line options. Additional alternative launchers can be built using this option, and this option can be used multiple times to build multiple additional launchers.

Command line arguments to pass to the main class if no command line arguments are given to the launcher

This option can be used multiple times.

Options to pass to the Java runtime

This option can be used multiple times.

Qualified name of the application main class to execute

This option can only be used if --main-jar is specified.

The main JAR of the application; containing the main class (specified as a path relative to the input path)

Either --module or --main-jar option can be specified but not both.

The main module (and optionally main class) of the application

This module must be located on the module path.

When this option is specified, the main module will be linked in the Java runtime image. Either --module or --main-jar option can be specified but not both.

Windows platform options (available only when running on Windows):

Creates a console launcher for the application, should be specified for application which requires console interactions

An identifier that uniquely identifies the application for macOS

Defaults to the the main class name.

May only use alphanumeric (A-Z,a-z,0-9), hyphen (-), and period (.) characters.

Name of the application as it appears in the Menu Bar

This can be different from the application name.

This name must be less than 16 characters long and be suitable for displaying in the menu bar and the application Info window. Defaults to the application name.

When signing the application package, this value is prefixed to all components that need to be signed that don't have an existing package identifier.
Request that the bundle be signed.
Name of the keychain to search for the signing identity

If not specified, the standard keychains are used.

Team or user name portion in Apple signing identities
Indicates that the jpackage output is intended for the Mac App Store.
Path to file containing entitlements to use when signing executables and libraries in the bundle
String used to construct LSApplicationCategoryType in application plist

The default value is "utilities".

URL of the application's home page
Location of the predefined application image that is used to build an installable package

(absolute path or relative to the current directory).

See create-app-image mode options to create the application image.

Path to a Properties file that contains list of key, value pairs (absolute path or relative to the current directory)

The keys "extension", "mime-type", "icon", and "description" can be used to describe the association.

This option can be used multiple times.

Absolute path of the installation directory of the application (on macos or linux), or relative sub-path of the installation directory such as "Program Files" or "AppData" (on Windows)
Path to the license file (absolute path or relative to the current directory)
Path to override jpackage resources (absolute path or relative to the current directory)

Icons, template files, and other resources of jpackage can be over-ridden by adding replacement resources to this directory.

Path of the predefined runtime image to install (absolute path or relative to the current directory)

Option is required when creating a runtime installer.

Windows platform options (available only when running on Windows):

Adds a dialog to enable the user to choose a directory in which the product is installed.

Generate an application package suitable for the host system:


For a modular application:
    jpackage -n name -p modulePath -m moduleName/className
For a non-modular application:
    jpackage -i inputDir -n name \
        --main-class className --main-jar myJar.jar
From a pre-built application image:
    jpackage -n name --app-image appImageDir


Generate an application image:


For a modular application:
    jpackage --type app-image -n name -p modulePath \
        -m moduleName/className
For a non-modular application:
    jpackage --type app-image -i inputDir -n name \
        --main-class className --main-jar myJar.jar
To provide your own options to jlink, run jlink separately:
    jlink --output appRuntimeImage -p modulePath \
        --add-modules moduleName \
        --no-header-files [<additional jlink options>...]
    jpackage --type app-image -n name \
        -m moduleName/className --runtime-image appRuntimeImage


Generate a Java runtime package:


jpackage -n name --runtime-image <runtime-image>
