Best Practices for Redeploying Ext Plugins in Liferay

Efficiently redeploying Ext plugins is crucial for development. Follow these recommended methods:

• Remove and Redeploy: The cleanest approach is to remove the plugin WAR file from the server and then redeploy it.
• ext.redeploy.enabled: Set ext.redeploy.enabled to "true" in your Liferay configuration.
• Remove XML File: Remove the text-plugin-[name of plugin].xml file from the deployed Liferay application and redeploy.
• Clean Instance Redeploy: For a fresh start, start from a clean Liferay instance and redeploy all plugins.

Unlock developer features with Liferay's developer mode:

• portal-developer.properties: Include portal-developer.properties during Java startup or in portal-ext.properties.
• Control Panel Configuration: Navigate to Server Administration in the Control Panel and set the portal.developer.mode property to "true".
• Copy Properties File: Copy portal-developer.properties from the portal's classes directory to the Liferay home directory and restart the server.
