Exception in thread "main" java.lang.NoSuchFieldError:Class org.testng.CommandLineArgs does not have member field 'java.lang.Integer port'

I'm trying to execute a file in TestNG without any xml file, just a direct run as shown on youtube. However, I'm getting the error below. Why is this?

Exception in thread "main" java.lang.NoSuchFieldError: Class org.testng.CommandLineArgs does not have member field 'java.lang.Integer port'
    at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:69)

TestNG version - 7.10.2 Eclipse version - Version: Oxygen.3 Release (4.7.3) Java version - java 21.0.2

What am I missing out?

I'm trying to execute a API in rest assured in TestNG.

Solution

  • Just change the testNG version from 7.10.x to an older version like 7.7.x or 7.8.x.

    It will 100% work.
