Cloud Run functions is a lightweight, event-based, asynchronous compute solution that allows you to create small, single-purpose functions that respond to Cloud events without the need to manage a server or a runtime environment.

There are two versions of Cloud Run functions:

• Cloud Run functions, formerly known as Cloud Functions (2nd gen), which deploys your function as services on Cloud Run, allowing you to trigger them using Eventarc and Pub/Sub. Cloud Run functions are created using gcloud functions or gcloud run. Samples for Cloud Run functions can be found in the functions/v2 folder.
• Cloud Run functions (1st gen), formerly known as Cloud Functions (1st gen), the original version of functions with limited event triggers and configurability. Cloud Run functions (1st gen) are created using gcloud functions --no-gen2. Samples for Cloud Run functions (1st generation) can be found in the current functions/ folder.

The Java Functions Framework Maven plugin (com.google.cloud.functions:function-maven-plugin) allows you to run Java Cloud Functions code on your local machine for local development and testing purposes. Use the following Maven command to run a function locally:

mvn function:run -Drun.functionTarget=your.package.yourFunction
