I created a new workspace with liferay version : 2025 Q3.6 and gradle version is 14.0.2 , after workspace is ready I created a rest-builder module and just doing buildREST in the gradle tasks .
I got javax issue
I did :
./gradlew upgradeJakarta
it updated jakarata but still I’m facing same issue .
I’m using Intellij Idea IDE .

Maybe check out the gradle.properties. It could contain a line like this: com.liferay.portal.tools.rest.builder.version=1.0.377 We had problems before because the version was too low after an upgrade. Try to comment it out, then it should use the most current version of the rest builder fitting to your workspace.
