# GraalVM Environment

<h2 class="pm-node nj-subtitle">An environment providing the Graal Java Virtual Machine</h2>

This notebook creates a **[reusable environment](https://nextjournal.com/nextjournal/environments)** with the [Graal JVM](https://graalvm.org/).

Nextjournal uses the the Graal JVM [Community Edition](https://github.com/graalvm/graalvm-ce-builds/). Note that the GraalVM version and installation directory are set as environment variables on the runtime.

Download the install tarfile.

```bash id=22f34710-72c9-46d3-bc78-b80130eec66c
file="graalvm-ce-java${JAVA_VERSION}-linux-amd64-${GRAAL_VERSION}.tar.gz"
path="graalvm/graalvm-ce-builds/releases/download/vm-${GRAAL_VERSION}/${file}"
url="https://github.com/${path}"

wget --progress=bar:force -P /results $url
```

tar -zxf [reference][nextjournal#reference#41b70c77-24a6-4a5e-b7c3-75b0dd080210] \
  -C $GRAAL_DIR --strip-components=1
```

And test.

```bash id=ddb404a8-852e-4539-b9fc-4910c9fc82c3
java -version
