Google Cloud GraalVM Samples

This directory contains code samples that depend on the Google Java Client Libraries and are compatible with GraalVM native image compilation.

Setup Instructions

You will need to follow these prerequisite steps in order to run these samples:

If you have not already, create a Google Cloud Platform Project.
Install the Google Cloud SDK which will allow you to run the sample with your project's credentials.

Once installed, log in with Application Default Credentials using the following command:
```
gcloud auth application-default login
```
Note: Authenticating with Application Default Credentials is convenient to use during development, but we recommend alternate methods of authentication during production use.
Install the GraalVM compiler.

You can follow the official installation instructions from the GraalVM website. After following the instructions, ensure that you install the Native Image extension installed by running:
```
gu install native-image
```
Once you finish following the instructions, verify that the default version of Java is set to the Graal version by running java -version in a terminal.

You will see something similar to the below output:
```
$ java -version
