Error when creating new project

[Sebastien Blanc]

I'm getting an exception at the last step of creating a new project of Spring Boot type :

What Forge version are you using? This change was introduced in 3.5.0.Final afaik

[Sebastien Blanc]

Ah okay , I'm still on an "old" 3.4.0 ;)

[Charles Moulliard]

I will add a comment within the doc page to mention that Forge >= 3.5 is required.

Can we close the ticket @sebastienblanc ?
