Building from source

Instructions (click to show)

Requirements:

• JDK 8+ (16+ for Fabric, 17+ for Minestom)
• Git (Optional)

To build UnifiedMetrics, you need to obtain the source code first. You can download the source from GitHub or use the Git CLI.

$ git clone https://github.com/Cubxity/UnifiedMetrics && cd UnifiedMetrics

Open a terminal in the cloned directory and run the following command. The following command will build all subprojects.

$ ./gradlew assemble -x signArchives

-x signArchives is required to skip signing, unless you have signing set up

To build a specific subproject, you can prefix it with the subproject path. For example:

$ ./gradlew :unifiedmetrics-platform-bukkit:assemble -x signArchives

The output artifacts can be found in subproject/build/libs.

API

Examples

Example plugins can be found under examples directory.

Gradle (Kotlin)

repositories {
    mavenCentral()

    // Snapshots repository (only required for -SNAPSHOT versions)
    maven("https://s01.oss.sonatype.org/content/repositories/snapshots/")
}

dependencies {
    // Replace this with the desired version
    compileOnly("dev.cubxity.plugins", "unifiedmetrics-api", "0.3.6")
}

Usage

Add :unifiedmetrics-api as a dependency (compileOnly/provided). Prefer using platform's service manager if possible.

import dev.cubxity.plugins.metrics.api.UnifiedMetricsProvider

/* ... */

val api = UnifiedMetricsProvider.get()
