I install plugin by file jar like in the docs say [Installing plugin offline in Katalon Studio | Katalon Docs](https://docs.katalon.com/katalon-platform/plugins-and-add-ons/katalon-store/katalon-studio-plugins/installing-plugin-offline-in-katalon-studio)

First, I try the solution reload plugin. I pasted jar files to folder Plugin of project then reload project. KS only recognize 1 plugin:

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:

```auto
<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!
