Why maven use the old version of the Vaadin plug-in when I run the project in IntelliJ?

Question

I use Wildfly 20 and IntelliJ latest version with vaadin-maven-plugin 14.2.2 in my pom.xml and pnpm enabled.

A very ugly problem happens what I can't understand why. When I run my project via IntelliJ run configuration something strange happens. IntelliJ uses an older version of vaadin-plugin namely vaadin-maven-plugin 14.2.0 which I don't have it in my pom.xml.

I have already tried mvn help:effective-pom to see if multiple versions of this dependency exists in pom and also checked all transitive dependencies using mvn dependency:tree

Anyone knows why this happens and what should I do to prevent it?

If I use wildfly plugin and execut wildfly:run I get following error

Try following steps:

• Do mvn clean install -U
• Open the project view in IntelliJ
• Right click the pom.xml file and
• select Maven - Reimport If this works for you IntelliJ will add the dependencies to the project
• Check the if the dependencies you need are added in File - Project Structure - Project Settings - Libraries and File - Project Structure - Modules - Dependencies.
