How to make Eclipse to report error when declared exception is not caught?
For example, if I declare method as

public int someMethod(int a, int b) throws IllegalArgumentException {
    ...
}

And then use it in another method like

public int anotherMethod() {
    ...
    return someMethod(a, b);
}

I want compiler to report error in anotherMethod, until I will catch IllegalArgumentException or declare another method as

public int anotherMethod() throws IllegalArgumentException {}

回答1:

Eclipse should actually report an error because you have an uncaught IOException in anotherMethod():

Unhandled exception type IOException

Only an unchecked exception (e.g. a RuntimeException) would cause the behaviour you are describing, but an IOException is a checked exception.

Maybe you have turned off error reporting in eclipse, but I doubt so. You can check this in Preferences / General / Editors / Text Editors / Annotations / Errors. make sure all checkboxes are checked.

Note: My answer refers to the original question asked before it was edited, which mentioned an IOException instead of an IllegalArgumentException.
