The problem is that we don't have a documents what is replacement in Maven 3 for many deprecated methods.

The problem is that we don't have a documents what is replacement for many deprecated methods in Maven 3.

After it we will can use newer methods from API ... and we will have an exception in runtime on older Maven.

[slachiewicz]

I agree that this is wrong, but if we will run tests with 3.6.3 we should sooner or later catch it

please look at #414
