I can't run my Spring Boot with Vaadin and vaadin4Spring appliction because of following exception:

What can be wrong and how to solve this issue?

Hi, try to build a snapshot version from the master and let us know if it can still be reproduced. The master is updated to Vaadin 8.

[artlomako]

Hi, sample with 2.0.0-SNAPSHOT works fine. How can I attach this version to my Maven project? I found only 0.0.7.RELEASE on https://mvnrepository.com/.

[mstahv]

If you build the snapshot locally you can just use 2.0.0-SNAPSHOT in your project (locally) as well. If you have maven proxy, you can probably install the artifacts there as well.

You can add http://oss.sonatype.org/content/repositories/vaadin-snapshots as a repository in your pom to download snapshots
