@missedone -

accessible: module Tryagain does not "exports Tryagain1" to module org.testng

This looks like there is Java modules involved.

@v91negi - Do you have a module-info.java in your project somewhere? What happens when you delete this file and try again?

Can you share more details about this, why module_info.java causing error?

from testng-eclipse.

@v91negi - If you have a module-info.java then it means that you are trying to leverage the modularisation capabilities that JDK9 and above provide. modules are basically a higher level grouping on top of package. Until JDK8 one could group classes into a package and there was no further grouping that was possible. JDK9 introduced the notion of modules wherein you could basically group a bunch of package into module.

I suggest that you read a bit about module so that it clears out the concept. After that the error message should be self explanatory. In a nutshell, you defined a module-info.java and so Java started expecting that you would tell which all packages are to be visible to the outside world (and to TestNG since TestNG also would be part of the outside world). Since nothing was visible and since TestNG is trying to access your packages, Java flags this as a problem.
