After updating to 7.9.1 from 7.8.0 my project is broken (Windows 10). In the Help, I clicked on ‘Check for Updates …’, opted for update to 7.9.1 and now my project is not runnable with 61 errors, which I’m not sure how to fix: ![image](https://europe1.discourse-cdn.com/katalon/original/3X/c/e/ce1906703095227983c7f291dee175ed6f5a1fec.png) ---

Hello @gdearest07 Please be noted that you will not be able to use **Check for updates…** to upgrade from v7.8x to v7.9+ due to the core engine upgrade. Download the latest version from [our website](https://www.katalon.com/download/). To reuse Preferences from previous versions, refer to [this guide](https://docs.katalon.com/katalon-studio/docs/katalon-studio-preferences.html#import-preferences). Then try again and report if you have encountered the issue. Jass ---

Hello @Jass . Thanks. When I was using 7.8.0, I saw the warning that on MAC (not on Windows), it’s not possible to use **Check for updates…** to upgrade from v7.8x to v7.9+. I don’t think that’s what caused the problem. By trial and error, I was able to get rid of the errors. For example, I looked into sample projects and noticed that they use: import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI and in my files it was: import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords … import WSBuiltInKeywords as WS So, I commented out what I had in my project and used: **import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI** instead. The other difference is : //import static JS.\* // not working in 7.9.1 **import static web.JS.** \* // works in 7.9.1 When I’m trying to run it, so far, so good. ---

Hi @Jass Thank you for you help. It looks like I did exactly what @duyluong suggested: "[duyluong](http://forum.katalon.com/u/duyluong)Katalon Developer [Jan 21](http://forum.katalon.com/t/bug-ks-7-9-does-not-recognize-webui/51243/26) Hi @Sdhongadi To download v7.8.2 packages, you can download from Github: [https://github.com/katalon-studio/katalon-studio/releases/tag/v7.8.2](https://github.com/katalon-studio/katalon-studio/releases/tag/v7.8.2). Back to the orginal issue, v7.8.2 and earlier this script are accepted by Groovy Compiler: ```auto import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords import WSBuiltInKeywords as WS import WebUiBuiltInKeywords as WebUI ``` but in v7.9.0 and onward, you should manually change it to because we use the new Groovy Eclipse compiler engine: ````auto import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI ```" ```` ---

Hi @gdearest07, In v7.9.0 onward, we apply new Groovy compiler that does not accept these imports: ```auto import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords import WSBuiltInKeywords as WS import WebUiBuiltInKeywords as WebUI ``` I agree that you should manually change to: ```auto import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI ``` and this will work in both v7.9+ and v7.8.2.
