Tools for refactoring Salesforce Apex code?

Question

Are there any tools available which help with Apex code refactoring?

With features like:

• Renaming classes and updating all references
• Renaming method names and updating all references
• Finding usages of class/method
• Finding redundant code
• Change Signature
• Convert Interface to Abstract Class
• Convert Abstract Class to Interface
• Extract Superclass
• Transform Parameters
• Replace Constructor with Factory Method
• Convert Method to Property
• etc

Something like ReSharper would be perfect :)

Note: I realise a similar question has been asked before, but that was 3 years ago, so hoping for a positive answer this time.

Answer 1

I know of two choices:

1. Illuminated Cloud plugin for IntelliJ
2. Welkin Suite based on Visual Studio

Both will meet most of your requirements.

But I believe IntelliJ + Illuminated Cloud is a better fit.

Both are licensed and pricy.

IntelliJ

• Renaming classes and updating all references +
• Renaming method names and updating all references +
• Finding usages of class/method +
• Finding redundant code +/- (If I remember well it highlights parts of the code which can be refactored to methods)
• Change Signature +
• Convert Interface to Abstract Class +/- (Hmm didn't try that but I think it can be done fairly well with IntelliJ refactoring capabilities
• Convert Abstract Class to Interface +/-
• Extract Superclass +
• Transform Parameters + (Extracting fields you mean?)
• Replace Constructor with Factory Method +
• Convert Method to Property +
