What is GitHub Actions Cache?

GitHub Actions Cache is a feature that allows you to store and reuse build artifacts and dependencies across multiple runs of your GitHub Actions workflows. This can significantly improve the performance of your workflows by avoiding the need to rebuild and reinstall these items each time the workflow is run.

How to use GitHub Actions Cache?

Using GitHub Actions Cache is straightforward. First, you need to add the following line to your workflow file:

<code>uses: actions/cache@v2</code>

This will install the GitHub Actions Cache action in your workflow.

Next, you need to specify the keys that will be used to identify the cache. You can do this using the key input:

<code>with:
  key: ${{ runner.os }}-maven-cache</code>

This key will be used to identify the cache and ensure that it is reused across multiple runs of the workflow.

Finally, you need to specify the path to the cache. You can do this using the path input:

<code>path: ${{ runner.temp }}/.m2</code>

This path will be used to store the cache.

What are the benefits of using GitHub Actions Cache?

There are several benefits to using GitHub Actions Cache:

• Improved performance: Caching build artifacts and dependencies can significantly improve the performance of your workflows by avoiding the need to rebuild and reinstall these items each time the workflow is run.
• Reduced build times: By reusing cached items, you can reduce the build time of your workflows. This can be especially beneficial for large or complex workflows.
• Improved resource utilization: Caching can reduce the amount of resources that are used by your workflows. This can lead to cost savings and improved performance.
• Easier workflow development: By caching items, you can reduce the complexity of your workflow files. This can make it easier to develop and maintain your workflows.
