Hi @KDanial,

Thank your for your helpful tip!

It took me some time since I did not get the Spring Scanner running with Confluence 9. Now I switched to Spring Java Config (I am more comfortable with) and the following allows to deploy the app:

<Import-Package>
  org.springframework.osgi.*;resolution:="optional",
  org.eclipse.gemini.blueprint.*;resolution:="optional",
  com.atlassian.confluence.plugins.createcontent.api.*;resolution:="optional",
  *
</Import-Package>

There was still an issue when I created a new page with this blueprint:

java.lang.RuntimeException occurred dispatching com.atlassian.confluence.plugins.createcontent.events.BlueprintPageCreateEvent to [com.example.plugins.tutorial.confluence.simplebp.MyBlueprintListener]

java.lang.ClassNotFoundException: com.atlassian.confluence.plugins.createcontent.api.blueprint.ContentBlueprint

With the (snipped) stack trace:

Then I added a compile scope dependency to the POM:

    <dependency>
      <groupId>com.atlassian.confluence.plugins</groupId>
      <artifactId>confluence-create-content-api</artifactId>
    </dependency>

And the “hello world blueprint project” works!

Thank you again!
