Vaadin Gradle plugin: Task vaadinBuildFrontend fails with dependency error - gradle

Question

My app is based on Spring Boot 2.2.5 including Vaadin 14. The project is built with Gradle 5.6.4 using the Vaadin Gradle Plugin 0.6.0
The Jenkins build pipeline fails with the following error:
Welcome to Gradle 5.6.4!
Here are the highlights of this release:
- Incremental Groovy compilation
- Groovy compile avoidance
- Test fixtures for Java projects
- Manage plugin versions via settings script
For more details see https://docs.gradle.org/5.6.4/release-notes.html
Starting a Gradle Daemon (subsequent builds will be faster)
