JavaPackager

JavaPackager is a Maven plugin which provides an easy way to package Java applications in native Windows, Mac OS X, or GNU/Linux executables, and generates installers for them.

SNAPSHOT versions are not published at Maven Central, so you have to install them manually.

How to use this plugin

Config your project

Add the following plugin tag to your pom.xml:

<plugin>
    <groupId>io.github.fvarrui</groupId>
    <artifactId>javapackager</artifactId>
    <version>1.1.0|1.1.1-SNAPSHOT</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>package</goal>
            </goals>
            <configuration>
                <!-- mandatory -->
                <mainClass>path.to.your.mainClass</mainClass>
                <!-- optional -->
                <bundleJre>true|false</bundleJre>
                <generateInstaller>true|false</generateInstaller>        
                <administratorRequired>true|false</administratorRequired>
                <platform>auto|linux|mac|windows</platform>
                <additionalResources>
                    <additionalResource>file path</additionalResource>
                    <additionalResource>folder path</additionalResource>
                    <additionalResource>...</additionalResource>
                </additionalResources>
                <linuxConfig>...</linuxConfig>
                <macConfig>...</macConfig>
                <winConfig>...</winConfig>
                [...]
            </configuration>
        </execution>
    </executions>
</plugin>

Package your app

Execute next command in project's root folder:

mvn package

And by default it will generate next artifacts in target folder:

Artifact	Description
`${name}`	Directory with the native application and other needed assets.
`${name}-${version}-runnable.jar`	Runnable JAR file.
`${name}_${version}.deb`	DEB package file if it's executed on GNU/Linux (requires dpkg-deb).
`${name}_${version}.rpm`	RPM package file if it's executed on GNU/Linux (requires rpmbuild).
`${name}_${version}.exe`	Setup file if it's executed on Windows (requires Inno Setup).
`${name}_${version}.msi`	MSI installer file if it's executed on Windows (requires WiX Toolset).
`${name}_${version}.dmg`	Disk image file if it's executed on Mac OS X (requires hdiutil).
`${name}_${version}.pkg`	PKG installer file if it's executed on Mac OS X (requires pkgbuild)
`${name}-${version}-${platform}.zip`	Zipball containing generated directory `${name}`.
`${name}-${version}-${platform}.tar`	Tarball containing generated directory `${name}`.
`${name}-${version}-${platform}.tar.gz`	Compressed tarball containing generated directory `${name}`.

⚠️ Installers generation will be ommited if target platform is different from current platform (see platform property).

Plugin configutation properties

Property	Mandatory	Default value	Description

Property	Mandatory	Default	Description
`linuxConfig`	❌	`null`	GNU/Linux specific properties.
`macConfig`	❌	`null`	Mac OS X specific properties.
`winConfig`	❌	`null`	Windows specific properties.

See Older documentation for previous versions properties.

⚠️ Be careful when using the platform property if your project uses platform dependent libraries, so the libraries of the current platform will be copied, not those required for the target platform. You can solve this problem using classifiers. Also, customized JRE and intallers generation will be ommited.

Plugin assets

Some assets, such as application icons and Velocity templates, could be placed in ${assetsDir} folder organized by platform.

${assetsDir}/
├── linux/
├── mac/
└── windows/

Icons

If icons are located in ${assetsDir} folders, it would not be necessary to specify the iconFile property:

${assetsDir}/
├── linux/
│   ├── ${name}.png     # on GNU/Linux it has to be a PNG file for DEB package
│   └── ${name}.xpm     # and XPM file for RPM package
├── mac/
│   └── ${name}.icns    # on Mac OS X it has to be a ICNS file
└── windows/
    └── ${name}.ico     # on Windows it has to be a ICO file

⚠️ If iconFile plugin property is not specified and it can't find the correct icon in ${assetsDir} folder, it will use an icon by default for all platforms.

Velocity templates

Velocity templates (.vtl files) are used to generate some artifacts which have to be bundled with the app.

It is possible to use your own customized templates. You just have to put one of the following templates in the ${assetsDir} folder organized by platform, and the plugin will use these templates instead of default ones:

${assetsDir}/
├── linux/
|   ├── control.vtl                         # DEB control template
|   ├── desktop.vtl                         # Desktop template
│   └── startup.sh.vtl                      # Startup script template
├── mac/
|   ├── customize-dmg.applescript.vtl       # DMG customization Applescript template
|   ├── Info.plist.vtl                      # Info.plist template
│   └── startup.vtl                         # Startup script template
├── windows/
|   ├── exe.manifest.vtl                    # exe.manifest template
|   ├── iss.vtl                             # Inno Setup Script template
│   └── wxs.vtl                             # WiX Toolset WXS template
└── assembly.xml.vtl                        # template for maven-assembly-plugin

Use default templates as examples.

An object called info is passed to all templates with all plugin properties.
