Error while executing the testNG.xml file

Question

I am getting the error below while executing the Java testNG.xml file in Eclipse:

[TestNGContentHandler] [WARN] It is strongly recommended to add "<!DOCTYPE suite SYSTEM "
http://testng.org/testng-1.0.dtd" >" at the top of your file, otherwise TestNG may fail 
or not work as expected.

Can anyone help with this?

Answer 1

I have upgraded my testNG version in POM.xml from 6.14.3 to

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>7.1.0</version>
    <scope>test</scope>
</dependency>

Changing version solved this error.

Answer 2
