b-validate | : eyes : Tiny and powerful Javascript type validate

From the information, I infer that you're trying to invoke the validate method of the Validator class.

Also, sounds like you have to grasp the concept of static and instance in OOPS. First I will give you an overview of the concept and then the answer.

There are two types of method and fields in Java.

Object/Instance Method and Fields:

• This is limited to the scope of individual objects of that class.
• You cannot call this method/Fields with that class name.
• The value present for a field in one object will not affect the value of others

Static Methods and Fields:

• This belongs to the class scope and it is shared across all objects of that class.

• If one objects change the field value, it will also reflect on other objects

• Static Fields can be called from the objects of that class but the static method can only be invoked from the defined class

Solution

The validate is a static method located in Validator class, So you have to call (Validator.validate(policy)).

You shouldn't need to clone each repository manually and use local hooks in the way you're doing -- if you have clone access during build time you should be able to do the normal installation approach

To ensure all of the hooks are pre-installed, you'll want to run pre-commit install-hooks as one of the commands in your dockerfile

This will ensure that all of the hook executables are properly cached in your image and then will be available later when you run pre-commit run ...
