How to avoid running test cases twice using maven command - maven

Question

I am developing a test automation project. I run the test cases with testNg plugin in eclipse. That's fine. But when I run test using mvn test command, maven runs the test cases twice. Things become worse when it execute from jenkins. It takes long time to finish all the test cases.
How could I fix the issue. My POM file is like below-
Please let me know how mvn command just run test cases only once.
Thanks

Answer 1

There exists multiple plugins, which might be enabling multiple executions. 'maven-surefire-plugin' is sufficient enough to run the tests, you may try commenting other plugins one by one and check which one is running the tests again.
