jbang-gradle-plugin

The JBang Gradle plugin allows JBang scripts to be executed during a Gradle build.

The plugin attempts to use an existing JBang installation. If no JBang installation is found, the plugin will install JBang by downloading and caching the latest version binaries (in your local Gradle cache directory) for subsequent runs.

Usage

This plugin adds a new task of type org.kordamp.gradle.plugin.jbang.tasks.JBangTask named jbang that accepts the following properties

Property	Type	System	Environment	Default	Required
script	String	jbang.script	JBANG_SCRIPT		✅
args	List<String>	jbang.args	JBANG_ARGS	[ ]	❌
trusts	List<String>	jbang.trusts	JBANG_TRUSTS	[ ]	❌
version	String	jbang.version	JBANG_VERSION	0.48.0	❌
installDir	Directory	jbang.install.dir	JBANG_INSTALL_DIR	$gradleUserHomeDir/caches/jbang	❌

script	The script to be executed by JBang.
args	The arguments to be used in the JBang script (if any)
trusts	If the script resides in a remote location, this parameter specifies what URLs should be trusted. See URLs from Trusted Sources for more information
version	If your environment lacks the JBang binaries in the PATH, you can specify the JBang version to be installed. The default value will be the plugin’s version

Task property values may be specified directly or using their respective environment variable, System property, or project property respectively, for example

$ gradle jbang -Djbang.script=hello.jsh -Djbang.args="Hello world"

If the org.kordamp.gradle.inline plugin were to be applied to your build (via settings.gradle) then you may invoke this plugin without modifying your build file

$ gradle org.kordamp.gradle:jbang-gradle-plugin:0.1.0:jbang -Pjbang.script=hello.java
