私はSpring Boot + Axon Frameworkの開発デモに取り組んでいます: https://www.youtube.com/watch?v=Jp-rW-XOYzA&list=PLgGXSWYM2FpOa_FTla-x5Wd10dpmgrRC4&index=54 . この例では、最新の依存関係のみを使用しており、他のものはそのまま保持しています。

コードを単純に実行すると、以下のエラーが発生し、すでに行に何か問題があります。私を案内してください。

エラー:-

java.lang.Error: Unresolved compilation problem: 
    Exception Exception is not compatible with throws clause in SpringAMQPMessageSource.onMessage(Message, Channel)
