Install Plugin from Jar File

To install a JAR as an IntelliJ plugin, follow these steps:

1. Prepare the JAR File

Ensure the JAR file is packaged correctly as an IntelliJ plugin. It should contain the necessary META-INF/plugin.xml file and all required dependencies.

2. Install the Plugin from Disk

1. Open IntelliJ IDEA.
2. Go to File > Settings (or IntelliJ IDEA > Preferences on macOS).
3. Navigate to Plugins in the left sidebar.
4. Click on the ⚙️ Gear icon at the top-right corner of the Plugins window.
5. Select Install Plugin from Disk from the dropdown menu.
6. In the file chooser, navigate to and select the JAR file you want to install.
7. Click OK to install the plugin.
8. Restart IntelliJ IDEA if prompted.

3. Verify Installation

After restarting IntelliJ IDEA:

1. Go back to File > Settings > Plugins.
2. Look under the Installed tab to confirm that your plugin is listed.

4. Activate the Plugin (If Needed)

If your plugin requires activation:

1. Go to File > Settings > Plugins.
2. Find your plugin under the Installed tab and ensure it's enabled (checkbox checked).
3. Apply and restart IntelliJ IDEA to activate the plugin.

That's it! Your JAR file should now be installed and working as an IntelliJ plugin.
