Calling keywords in test cases causes error "Unresolved compilation problem"

Hi.

I am using Windows 10 with Katalon Studio 8.1.
I have noticed that for some time now I regularly receive the following issue.

We have a keyword titled gVar and it has classes such as gVar.Set_PE_Database, which are used in test cases.

For some time now, seemingly at random, I will run a test script and it will generate this error.

The “Unresolved compilation problem” error is always with reference to a test script using a class or method under the gVar keyword.

The solution is to go into the Katalon project and delete the bin and Libs folders, and the .classpath and .project, and to reinitialize the katalon project, after which it works fine. But it keeps appearing again and again.

But this may be a bug in Katalon.

Does anything show up here?

Description: Warnings

These are issues I have been meaning to clean up. But it strange that this issue sometimes does and does not appear.

@duyluong @ThanhTo

Any advice guys?

You have 15 errors in “Description: Errors”. These are caused by your coding mistakes, not by Katalon Studio’s problem. You have to fix all of these error in your codes before running your tests. Otherwise your test will never ran successful.

For example, 3rd line

Groovy:Invalid duplicate class definition of class gVar.ExecuteDB : The sources C:\KatalonProject\Non-PE_Core_2\Keywords\gVar\ExecuteQuery.groovy and C:\KatalonP    ...(can not see what follows)

What this message tells?

You have 2 *.groovy files

  • C:\KatalonProject\Non-PE_Core_2\Keywords\gVar\ExecuteQuery.groovy and
  • C:\KatalonP …(can not see what follows)

These files contain the same code fragment:

package gVar

class ExecuteDB {
    ...
}

you need to get rid of the duplication.

Thank you. I will do so.

Hello, i am facing the similar issue, the test suit runs absolutely fine on Katalon IDE and one RTE machine, but on another RTE machine it throws below exception…

The above message tells that you have 2 modules you created:

  • common.VerifyViaText
  • DigitalBanking_SanityLogin

Please share the source code of them.

Also, the above message indicates that common.VeirfyViaText has a “UnsesolvedCompilationProblem” at the line#1. The line#1 would be a package xxxxx statement, but it could be wrong somehow. Please check if you wrote the code right.

Thanks for the reply…below is the code for Keywords. It has been consistently working fine. Then it errored out on the day of deployment and worked it again today. has no clue about the behavior.
this is how it is being called in the test…

I feel the package name common is questionable.

package common

It looks too generic. I guess that your deployment environment somehow dislikes the package name common, though I have no concrete idea why. How about renaming the package to make it more unique so that you take less risk of duplication. For example, common --> manojpuri.common.
