# JPackage Gradle Plugin

Gradle plugin for [jpackage](https://openjdk.java.net/jeps/343) tool available since JDK-14.

## Finding jpackage

Plugin searches for ```jpackage``` executable using the following priority list:

1. Configured toolchain

2. ```java.home``` system property.

## Configuration

There are generic ```jpackage``` parameters as well as OS-specific parameters for OS X, Linux, Windows.
OS-specific parameters are processed when build is done on the corresponding OS.

If some generic parameters should have different values based on OS then they should be placed into configuration blocks:

* windows
* mac
* linux

*Example:*

```kotlin
// Windows specific parameters will be processed only during Windows build
winMenu = true
winDirChooser = true

mac {
// Generic parameter value for OS X build
icon = "icons/icons.icns"
}

windows {
// Generic parameter value for Windows build
icon = "icons/icons.ico"
}
```

### Image Type

|Plugin Value|JPackage Type|
|---|---|
|DEFAULT|Default image type, OS specific|
|APP_IMAGE|app-image|
|DMG|dmg|
|PKG|pkg|
|EXE|exe|
|MSI|msi|
|RPM|rpm|
|DEB|deb|

### Default Command-Line Arguments

Default command line arguments are passed to the main class when the application is started without providing arguments.

_Example:_

```kotlin
arguments = listOf(
"SomeArgument",
"Argument with spaces",
"Argument with \"quotes\""
)
```

### JVM Options

Options that are passed to the JVM when the application is started.

_Example:_

```kotlin
javaOptions = listOf(
"-Xms2m",
"-Xmx10m"
)
```

### jlink options

Options that are passed to underlying jlink call.

_Example:_

```kotlin
jLinkOptions = listOf(
"--strip-native-commands",
"--strip-debug"
)
```

### jpackage Environment Variables

Optionally environment variables can be passed to ```jpackage``` executable process.

_Example:_

```kotlin
jpackageEnvironment = mapOf(
"GRADLE_DIR" to project.projectDir.absolutePath,
"BUILD_DIR" to project.buildDir.absolutePath
)
```

```null``` values as well as ```null``` or empty keys are ignored.

## Logging

Plugin uses ```LogLevel.INFO``` to print various information about toolchain, jpackage parameters, etc. Use gradle
option ```--info``` to check this output.

## Dry Run Mode

To execute plugin tasks in dry run mode without calling ```jpackage``` set property```jpackage.dryRun``` to true.

_Example:_

```shell
$ ./gradlew clean build jpackage --info -Djpackage.dryRun=true
```

## Configuration Cache

This plugin is not compatible with Gradle [configuration cache](https://docs.gradle.org/current/userguide/configuration_cache.html).

## Examples

* [Modular Application with Full Runtime](doc/examples/ModularFullRuntime.md)
* [Non-Modular Application](doc/examples/Non-ModularApplication.md)
