# `ghcr.io/making/buildpacks/opentelemetry-javaagent`
⚠️ This project will be no longer maintained after paketo buildpack for opentelemetry is released.
**Use https://github.com/paketo-buildpacks/opentelemetry instead when it's released. **
The OpenTelemetry Java Agent Buildpack is a Cloud Native Buildpack that contributes the OpenTelemetry Java Agent.
## Behavior
This buildpack will participate if all the following conditions are met
* the build plan contains `jvm-application`
* The `$BP_OPENTELEMETRY_ENABLED` is set to `true` (**the breaking change since 0.2.0**)
The buildpack will do the following:
* Contributes a Java agent to a layer and configures `JAVA_TOOL_OPTIONS` to use it
This buildpack does not configure Java system properties (`-D` flags) or as environment variables for the agent.
See [the configuration documentation](https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/docs/agent-config.md) for the full list of configuration items.
## Example
```
git clone https://github.com/making/hello-servlet.git
pack build hello-servlet \
--path hello-servlet \
-e BP_OPENTELEMETRY_ENABLED=true \
--buildpack paketo-buildpacks/java \
--buildpack ghcr.io/making/buildpacks/opentelemetry-javaagent \
--builder paketobuildpacks/builder:base
```
```
docker run \
