jandex-gradle-plugin

---

Runs jandex on a Gradle project.

Usage

Option #1

buildscript {
    repositories {
        gradlePluginPortal()
        mavenCentral()
    }
    dependencies {
        classpath 'org.kordamp.gradle:jandex-gradle-plugin:2.3.0'
    }
}
apply plugin: 'org.kordamp.gradle.jandex'

Option #2

plugins {
    id 'org.kordamp.gradle.jandex' version '2.3.0'
}

This will add a jandex task to your build, which will analyze the main sourceSets by default, the generated index will be placed in ${project.tasks.processResources.destinationDir}/META-INF/jandex.idx.

ℹ️	Requires Java 11+ and Gradle 8+.

Configuration

Plugin configuration

The following properties can be specified in the jandex task configuration

Name	Option	Property	Type	Default Value
processDefaultFileSet	jandex-process-default-file-set	jandex.process.default.file.set	boolean	true
includeInJar	jandex-includein-jar	jandex.include.in.jar	boolean	true
indexName	jandex-index-name	jandex.index.name	String	jandex.idx
indexVersion	jandex-index-version	jandex.index.version	Integer
destination			File	build/jandex/jandex.idx
sources			ConfigurableFileCollection	sourceSets.main.output.classesDirs

ℹ️	The generated index file will be copied to build/resources/main/META-INF/jandex.idx during the invocation of the `processResources task if the includeInJar property is set to true.

Task properties may be defined on the command line using their option name, or their property name, such as

$ gradle jandex --jandex-index-name foo.idx
$ gradle jandex -Pjandex.index.name=foo.idx
$ gradle jandex -Djandex.index.name=foo.idx
$ set JANDEX_INDEX_NAME=foo.idx
$ gradle jandex

Jandex Version

This plugin relies on Jandex 3.1.7 to perform its job, however you may configure a different version if needed. Simply add the desired version (for the maven coordinates io.smallrye:jandex:<version>) to the jandex extension as shown next

jandex {
    version = '3.5.0'
}

⚠️	This plugin supports Jandex 3 as a minimum since version 1.0.0.

Reproducible Jandex indexes

To generate reproducible Jandex indexes, serialized index representations are equal across all builds, Jandex version 3.5.0 or newer is required.

To enable reproducible jar files in Gradle, visit the Gradle docs.

Migration

Starting with version 0.9.0 the chosen Jandex dependency must be resolved using explicit repositories, in other words, it is no longer part of the plugin’s default classpath. Failure to declare a repository from which this dependency may be resolved will result in a build failure.
