You have the option to generate Apex classes using the CLI. By default, the class is generated in the directory where you initiate the command. The standard DX project template assumes that you intend to produce your Apex classes in the <package directory>/force-app/main/default/classes directory. To create classes in this specific directory, make sure to switch to it before executing the command.
sfdx force:apex:class:create -n myclass
If you find yourself in a different directory, you can use the “-d” parameter to specify either an absolute or relative path to designate the location where you wish to store your Apex class files. If you omit specifying an absolute or relative path and the directory doesn’t exist, the CLI will make an attempt to create it for you.
sfdx force:apex:class:create -n myclass -d ../force-app/main/default/classes
The command produces two files:
- myclass.cls-meta.xml—metadata format
- myclass.cls—Apex source file
The default behavior of the command is to generate a basic framework for an Apex class. Nevertheless, you have the option to choose from various templates based on your specific creation requirements.
