I am trying to update GWT version for this project (
pentaho/pentaho-platform: Pentaho BA Server Core (github.com)
(Branch 9.2 R). They are using GWT in module user-console.
I simply changed version for gwt-servlet, gwt-user, gwt-dev, gwt-maven-plugin from 2.5.1 to 2.9. But i am taking errors.
My current pom and errors in attachment.
Thank you for answers ;)
