Issue

  • Deploying an EXT extension results in the extension being lost after the environment restarts.

Environment

  • Quarterly Releases 2023.Q3.3+.
  • PaaS

Resolution

  • The use of EXT modules is discouraged. Please explore alternative extensions before proceeding, if possible.
  • Starting from 2023.q3.3+, the marketplace/override is no longer used so you will need to create a custom deployment script to deploy it.
    1. Create the directory liferay/configs/common/custom-portal/ and place the compiled <ext-module>.jar (renamed without the version) into this directory.
    2. Create the deployExtOverride.sh script in the liferay/configs/common/scripts/pre-startup/ directory and deploy it.
  • In the future, ext modules are expected to be deployable without the need for a custom script (LPD-19756)

deployExtOverride.sh

#!/usr/bin/env bash

# (1) Remove old ext module placement
rm -f /opt/liferay/osgi/marketplace/override/<ext-module>.jar

# (2) Replace the module
mv /opt/liferay/osgi/portal/<ext-module>.jar /opt/liferay/osgi/portal/<ext-module>.jar.old
mv /opt/liferay/custom-portal/<ext-module>.jar /opt/liferay/osgi/portal/<ext-module>.jar

# (3) Clean
rm -Rf /opt/liferay/custom-portal/
