Can't build maven Vaadin 11 starter pack, missing dependency? - maven

Question

I can't build the maven Vaadin 11 starter pack like mentioned in the tutorial section of the doc. It seems that a package is missing, which provide an #Helper annotation. I tried to add the dependency in the pom.xml but no luck.
Here's the log from Maven :

Here is the pom.xml section with the dependency I added :
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>flow-documentation-parent</artifactId>
<version>1.1-SNAPSHOT</version>
<scope>compile</scope>
</dependency>
</dependencies>
Here is the link to the tutorial : https://vaadin.com/docs/v11/flow/introduction/tutorial-get-started.html
Does anyone know how to fix the dependency ?

Answer 1

You can remove all references to the #Helper annotation from the code. It's only used by our own internal tests that verify the tutorial code compiles.
I've created a ticket about fixing the tutorial and/or the code so that this shouldn't be an issue in the future.
