Excluding a unit test of a particular file using maven

Question

I am working on a project, which I recently got and while running unit tests using mvn test.

So, I go to different modules and run the above command using cmd and while doing so I came to know that there are two test cases in 2 files, which are failing intermittently (this was mentioned in the comments above that methods).

So, I am thinking of skipping those test cases only and proceeding ahead for now. I tried to find it here but only thing I could find her is excluding test cases of a particular module.

I want to exclude test1() of A.java and test2() of B.java

I found below:

# Exclude one test method 
mvn verify -Dtest=!LegacyTest#testFoo
# Exclude two test methods
mvn verify -Dtest=!LegacyTest#testFoo+testBar

in this link, but not sure how correct above method is and how to use it in my case, since I have not used maven before

Commands I have tried:

mvn verify -X -Dtest=!A#test1,!B#test2
mvn test -X -Dtest=!A#test1,!B#test2

Error trace which I got after running above commands:

Answer 1

In the link, they say this following code run multiple test :

mvn test -Dtest=AppTest,Web*

So may be to exclude multiple :

mvn verify -Dtest=!A#test1,B#test2

I didn't try, but it seems logical.

---EDIT---
You can also use the plugin maven-surefire-plugin like that

---EDIT 2 ---
I try and success, todo that verify in first that you use maven-surefire-plugin with version > 2.19 (add -X to get debug the version is printed); then your command will be :

mvn test -Dtest=!A#test1,!B#test2
