Vaadin framework 8.18.0 has dependency to old Liferay version

[mikke-alekstra]

The vaadin-server-8.18.0 has a dependency:
com.liferay.portal.kernel.util;resolution:=optional;version="[7.0.0,49.0.0)"

The new vaadin-portlet-8.18.0 has a dependency:
com.liferay.portal.kernel.util;version="[7.0,8)"

Deploying vaadin-portlet to Liferay causes an exception

2023-01-04 11:57:46.307 ERROR [fileinstall-directory-watcher][DirectoryWatcher:1173] Unable to start bundle: file:/opt/liferay/osgi/modules/vaadin-portlet-8.18.0.jar

I'm using Liferay CE 7.4.3.22 that was released last April. Liferay 7.4.3.22 contains the following versions:
com.liferay.portal.kernel bundle version 47.0.1
com.liferay.portal.kernel.util version 35.0.0

I edited MANIFEST.MF in vaadin-portlet by setting dependency
com.liferay.portal.kernel.util;version="[7.0,36)"
and vaadin-portlet seemed to start properly in my test bench.

Latest Liferay version is 7.4.3.57 and it contains versions:
com.liferay.portal.kernel bundle version 92.1.1
com.liferay.portal.kernel.util version 51.0.0

At least vaadin-portlet Liferay dependency should be updated to a more recent version. Preferrarly update all Vaadin framework's Liferay dependencies close to the latest version of Liferay.

Cheers!

Hi, have you checked our release notes

Separated portlet support code out of vaadin-server into its own package, vaadin-portlet. This will break your build if your application makes use of Portlet classes and you do not import the vaadin-portlet dependency.

So you need to add dependency to vaadin-portlet in pom.xml.

But, if it is not about that, maybe something has went wrong when we did this.

Hi, yes I have, thanks.

I got the error just by deploying Vaadin 8.18.0 to an empty Liferay 7.4.3.22 Docker environment. There seems to be a dependency to an old Liferay version in vaadin-portlet package.

If you update vaadin-portlet's old dependency I might be worth in updating all Liferay dependencies in Vaadin 8 framework as Liferay throws out a new release every week and 7.4.3.22 is ~30 releases old.

I think this issue is happening because there is no bnd.bnd in vaadin-portlet and one in the vaadin-server does reflect current architecture correctly. I think liferay kernel etc. versions should be defined in bnd.bnd of vaadin-portlet instead of vaadin-servlet etc.
