There is a limitation
with liferaycloud/jenkins:2.492.3-lts-jdk21-6.0.3 that keeps the CI
from working with different JDKs (i.e. a branch or repository with
Java 8 and another with Java 21 when upgrading from one version of
Liferay to another).
This is related to the breaking changes introduced with https://help.liferay.com/hc/en-us/articles/33476891762317-1-14-2025-Service-Release-Updates.
The only alternative to this right now is to update LCP_CI_GRADLE_JDK
every time a build needs to be done with one or another JDK, which
makes CI not continuous.
