Read write on a google sheet

Hi Community,

I followed this tutorial to read/write in a Google Sheet :slight_smile: Integrating Google sheet with Katalon Studio | by Prashant Bhatasana | AppGambit | Medium

But, I have many issue with import (in step 3) and i have this message :
Groovy:unable to resolve class …

I try Ctrl+Maj+O but always the same error message.

1 - how to get rid of these import errors ?

2 - Has anyone ever managed to read and write in a Google sheet?

Thank you

hello… in short: import class…
longer … good habit is to show whole error message …
otherwise you will end-up like in that joke:
… flight log record: something is wrong in cabin …
… maintenance crew record: we fixed something …

It seems that you don’t understand how to resolve external dependencies for you test scripts.

The following document describes how to add the jars into your katalon project.

You FAILED to follow the tutorial. The tutorial writes:

Or else you need to add the following External Libraries in your Katalon Studio project.
For External Libraries Goto Project > Settings > External Libraries > Add new libraries.
… (a lot more jars)

The how you can get the google-api-client-1.22.0.jar?

Answer: search for it in Google with keyword “Maven Central google-api-client”.

The Google will suggest you that you should visit:

In the page you will see a list of the versions of the google-api-client. You want to choose any one, and click the link. Say, you chose 2.0.0, then you will see

In the page you will find a link to the jar.

By clicking the link, you will get the jar file downloaded to your machine. Then you want to move the jar file into the Drivers folder of your project.

Repeat this processing for all other required jar files.

… tiresome? Yes, very much. However you have to do it. Otherwise, you would never be able to use google sheet in Katalon Studio.

Hi Andrej_Podhajsky,

I don’t understand any thing what you wrote.

This error message is the same for all the line in the Problems Pane :

Integrating Google sheet with Katalon Studio | by Prashant Bhatasana | AppGambit | Medium wrote that you need the

  • google-api-services-sheets-v4-rev483–1.22.0.jar

Have you downloaded the jar and locate it into the project’s Drivers folder? I guess, not.

Please show us which jars your Drivers folder now contains.

Thak you @kazurayam but 1 have one error now.

I re-imported all the libraries and one is a problem because it is highlighted in red:


it concerns this line:

private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

I removed it but it remains mandatory.

I am stuck again can someone help me please ?

:sob: :sob: :sob: :smiling_face_with_tear: :sob:

I found solution.
i replace this import

import; // old
import;  // old

by this import

and no red underline

Thank you very much for your answer
