# Heroku Buildpack for the JDK [![CI](https://github.com/heroku/heroku-buildpack-jvm-common/actions/workflows/ci.yml/badge.svg)](https://github.com/heroku/heroku-buildpack-jvm-common/actions/workflows/ci.yml)

This is the official [Heroku buildpack](https://devcenter.heroku.com/articles/buildpacks) for [OpenJDK](http://openjdk.java.net/). It only installs the JDK, and does not build an application. It is used by the [Java](https://github.com/heroku/heroku-buildpack-java), [Scala](https://github.com/heroku/heroku-buildpack-scala), and [Clojure](https://github.com/heroku/heroku-buildpack-clojure) buildpacks.

## Usage from a Buildpack

This is how the buildpack is used from another buildpack:

```bash

JVM_BUILDPACK_URL="https://buildpack-registry.s3.us-east-1.amazonaws.com/buildpacks/heroku/jvm.tgz"

mkdir -p /tmp/jvm-common

curl --silent --fail --retry 3 --retry-connrefused --connect-timeout 5 --location $JVM_BUILDPACK_URL | tar xzm -C /tmp/jvm-common --strip-components=1

source /tmp/jvm-common/bin/util

source /tmp/jvm-common/bin/java

install_java_with_overlay ${BUILD_DIR}

```

## Standalone Usage

You may install the JVM buildpack into your app by running:

```

$ heroku buildpacks:set heroku/jvm

```

If you want to use the edge version (the code in this repo), run this instead:

```

$ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-jvm-common.git

```

Then it may be used by itself, or with another buildpack using [multiple buildpacks](https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app).
