What is the current behavior?

maven allure-maven Goal: allure:aggregate requires a result folder in the target folder, which is not configurable

Code:

allure-maven/src/main/java/io/qameta/allure/maven/AlureAggregateMojo.java

Line 41 in 817846d

Path target = Paths.get(child.getBuild().getDirectory());

It is not possible to aggregate several Maven modules if you have defined your own results folder
like this:
<resultsDirectory>${project.basedir}/allure-results</resultsDirectory>

If the current behavior is a bug, please provide the steps to reproduce and if possible a mvn allure:aggregate

What is the expected behavior?

results folder can be outside of the target folder

What is the motivation / use case for changing the behavior?

we wan´t to save the results and target is cleaned up during normal maven prozess
