How can I set Maven TestNG project return code according to failed tests?

Question

My selenium test suit is managed by Maven and TestNG.
All works perfect, in case of particular tests failure I have perfect reports created with Extent Reports.
The problem is that Maven return code is always 0, both if all the tests passed and if several tests failed while we need to have indication for tests failures in Maven return code.
So far I couldn't find how can I do that.
My pom.xml file is:

Answer 1

Inside <configuration> Try to add

<testFailureIgnore>true</testFailureIgnore>

inside maven-surefire-plugin.

Set this to "true" to ignore a failure during testing. Its use is NOT RECOMMENDED, but quite convenient on occasion. Default value is: false. User property is: maven.test.failure.ignore.

Maven command to execute: mvn clean compile test

Complete Code:

<plugins>
    <plugin>

            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.2</version>
