How to avoid SonarQube issue about abstract exceptions?

Question

I am using SonarQube for my code quality analysis. I am coding in java with the use of AbstractJavaSequence from AdroidLogic API.

Many of my project classes extend this class and override execute method which by default declare throws Exception. The SonarQube analysis raises an issue, stating that the class uses a generic exception instead of specific one.

How can I resolve this SonarQube issue?

Answer 1

Just because the method you are overriding throws Exception, it doesn't mean you have to.

You are free to not declare that you throw any exceptions at all, or to throw specific exceptions instead:

public abstract class ParentClass {
    abstract void doSomething() throws Exception;
}

These are all valid (obviously, not all at once):

public class ChildClass extends ParentClass {
    public void doSomething() {
    }

    public void doSomething() throws MyException {
    }

    public void doSomething() throws Exception {
    }
}

There's no reason for you to carry on their bad practices.
