Then I use the second solution is choose install plugin from menu “Tools”. But it install only 1 plugin file. After install success it will disable Install like in the picture:

Whenever I close and reopen KS the installed plugin will be ereased and have to reinstall it.

Anyone have other solution to install plugin offline?

Hi @qaat.hanh,

Thank you for sharing your issue. Sorry for the late response.

I would like to suggest some workarounds here, please let me know if it works/ not work:
It seems like you’re encountering issues with offline plugin installation in Katalon Studio (KS). Here’s an analysis of the problem and suggestions for alternative solutions:

1. Verify Plugin Compatibility
Ensure the .jar files are compatible with your Katalon Studio version. Plugins designed for older versions may not work correctly with newer releases, or vice versa.

2. Proper Placement of Plugins

  • Place all .jar files in the Plugins folder located in the root directory of your Katalon Studio project.
  • Make sure the folder structure is as follows:
    <Project Root>
├── Plugins
│   ├── plugin1.jar
│   ├── plugin2.jar
  • Reload the project by going to File > Reload Project.

3. Ensure Proper Installation
For the “Tools > Install Plugin” option:

  • Install plugins one at a time as you’re already doing.
  • After installation, verify the plugin is loaded by checking Help > About Katalon Studio > Plugins.

4. Prevent Plugins from Being Erased
If plugins are removed after restarting KS, this could indicate an issue with:

  • File Permissions: Ensure that the Plugins folder and installed plugin files are not write-protected.
  • Cache Corruption: Clear the KS cache by deleting the .metadata folder in the Katalon Studio workspace directory and relaunch KS.

If all of these cannot help, please consider about installing plugins from Katalon Store. Thank you!
