It's conceivable in some cases that you might want to package multiple functions together. For such scenarios you can use
`spring.cloud.function.function-class` property to list several classes delimiting them by `;`.
For example,
```
--spring.cloud.function.function-class=function.example.UpperCaseFunction;function.example.ReverseFunction
```
Here we are identifying two functions to deploy, which we can now access in function catalog by name (e.g., `catalog.lookup("reverseFunction");`).
For more details please reference the complete sample available https://github.com/spring-cloud/spring-cloud-function/tree/master/spring-cloud-function-deployer/src/it/simplestjar[here].
