OpenTelemetry Semantic Conventions for Java

Java code-generation for the OpenTelemetry Semantic Conventions.

Published releases

Published releases are available on maven central. Replace {{version}} with the latest released version:

Artifact `{group}:{artifcatId}:{version}`	Latest Version	Description
`io.opentelemetry.semconv:opentelemetry-semconv:{{version}}`		Generated code for stable semantic conventions. NOTE: Although this is for stable semantic conventions, the artifact still has the -alpha and comes with no compatibility guarantees. The goal is to mark this artifact stable.
`io.opentelemetry.semconv:opentelemetry-semconv-incubating:{{version}}`		Generated code for experimental semantic conventions. NOTE: This artifact has the -alpha and comes with no compatibility guarantees. Libraries can use this for testing, but should make copies of the attributes to avoid possible runtime errors from version conflicts.

Maven

<project>
  <dependencies>
    <!-- Stable semantic conventions. Note: generated code is still subject to breaking changes while published with "-alpha" suffix. -->
    <dependency>
      <groupId>io.opentelemetry.semconv</groupId>
      <artifactId>opentelemetry-semconv</artifactId>
      <version>{{version}}</version>
    </dependency>
    <!-- Incubating semantic conventions. Breaking changes expected. Library instrumentation SHOULD NOT depend on this. -->
    <dependency>
      <groupId>io.opentelemetry.semconv</groupId>
      <artifactId>opentelemetry-semconv-incubating</artifactId>
      <version>{{version}}</version>
    </dependency>
  </dependencies>
</project>

Gradle

dependencies {
  // Stable semantic conventions. Note: generated code is still subject to breaking changes while published with "-alpha" suffix.
  implementation "io.opentelemetry.semconv:opentelemetry-semconv:{{version}}"
  // Incubating semantic conventions. Breaking changes expected. Library instrumentation SHOULD NOT depend on this.
  implementation "io.opentelemetry.semconv:opentelemetry-semconv-incubating:{{version}}"
}

Requirements

Java 17 or higher is required to build the projects in this repository. The built artifacts can be used on Java 8 or higher.

To use these artifacts, you must also depend on io.opentelemetry:opentelemetry-api:{{version}}. See opentelemetry-java releases for more information.

Android Requirements

An additional requirement for apps supporting older versions of Android on top of desugaring is the need to set the Gradle property android.useFullClasspathForDexingTransform for debug builds. Please see this pull request on the OpenTelemetry Android Extension for details.

Generating semantic conventions

Requires docker.

In a shell, execute the following gradle tasks:

./gradlew clean generateSemanticConventions --console=plain
./gradlew spotlessApply

This will download the version of open-telemetry/semantic-conventions defined in the semanticConventionsVersion variable of build.gradle.kts and generate semantic conventions classes from the release contents.
