Looks like it doesn’t reproduce. Just add a line with sed -i "s/\"14\.5\.1\"/\"14\.5\.2\"/g" base-starter-spring-gradle/build.gradle after the git clone… in above script.

Now:

Before:

Thank you.

OK below is my reproducer.

1. Run the script below. This will start a docker container with the gradle spring boot sample run via ./gradlew bootRun
2. wait until you see Completed initialization… in the docker logs.
3. Open http://localhost:8080 in your browser

It doesn’t look too weird but notification is not working.

To see a working version, delete the ./base-starter-spring-gradle (might require sudo…), and change the line with echo 'vaadin.pnpm.enable = true' >> … to echo 'vaadin.pnpm.enable = false' >> ….

#!/bin/sh

git clone https://github.com/vaadin/base-starter-spring-gradle

echo 'vaadin.pnpm.enable = true' >> ./base-starter-spring-gradle/src/main/resources/application.properties

cat > ./base-starter-spring-gradle/docker-run.sh<< EOF
#!/bin/sh

cd /var/app
./gradlew bootRun
EOF

chmod 755 ./base-starter-spring-gradle/docker-run.sh

docker run -d --name vaadin-bug  --rm  -v  `pwd`/base-starter-spring-gradle:/var/app -p 8080:8080 --entrypoint /var/app/docker-run.sh adoptopenjdk:11-hotspot

docker logs -f  vaadin-bug
