Spring Boot “kotlin-maven-plugin” not found

I created a new Spring Boot Project using the Spring Initializr (https://start.spring.io/). I didn’t change anything after downloading. I entered spring-boot:run to run the application. I get the following error:

[ERROR] Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:1.9.25:compile (compile) on project FlaPo2: Plugin not found: all-open -> [Help 1]

I added the following Dependencies

• Spring Web
• Spring Data JPA
• Docker Compose Support
• Spring DevTools
• Spring Security

I tried to change versions of the plugin. I also have Internet Connection.
In the past already ran other projects created by spring initializr on the same machine and it worked.

If it helps: My Java Version is 21.0.4 and my Maven Version is 3.6.3. I use Kotlin.

This is my pom.xml File (I didn’t changed anything after downloading it):
