XaGUI 1.6.1 is available from Maven Central.

repositories {
    mavenCentral()
}

dependencies {
    implementation 'eu.xap3y:xagui:1.6.1'
}

XaGUI is a library, so it normally needs to be included in your plugin JAR:

plugins {
    id 'java'
    id 'com.gradleup.shadow' version '8.3.6'
}

tasks.named('shadowJar') {
    relocate 'eu.xap3y.xagui', 'com.example.myplugin.libs.xagui'
}

tasks.named('build') {
    dependsOn tasks.named('shadowJar')
}

Replace com.example.myplugin with your own package. Relocation avoids conflicts if another plugin bundles a different XaGUI version.

If your server provides XaGUI as a separate plugin, use compileOnly and declare that dependency in your plugin metadata. Do not both shade XaGUI and depend on the standalone plugin.

Projects using XaGUI's Paper adapter can also add implementation 'eu.xap3y:xagui-paper:1.6.1'. Keep both artifacts on the same version. Core works without it and falls back to Bukkit text APIs.

Next: initialize the library and create a menu.
