Node 'dialog [cq:Dialog]' is not allowed as child of node with types [nt:folder] about aem-nodetypes

[kwin]

This has nothing to do with this project, but the parent nodetype of "/apps/msm/myapp-blueprint/jcr:content" must be a nodetype allowing a child of type cq:Dialog. Usually you use cq:Component.

Hello kwin.

Please note the node structure is created by AEM. So, I assume there is no mistake in the node types definition.
As far as I undestand, the error is introduced by the filevault-package-maven-plugin, which is using the aem-nodetypes defined in this Github project, as configured by default in the pom.xml:

                <plugin>
                    <groupId>org.apache.jackrabbit</groupId>
                    <artifactId>filevault-package-maven-plugin</artifactId>
                    <extensions>true</extensions>
                    <version>1.1.6</version>
                    <configuration>
                        <filterSource>src/main/content/META-INF/vault/filter.xml</filterSource>
                        <validatorsSettings>
                            <jackrabbit-nodetypes>
                                <options>
                                    <!-- use the nodetypes and namespaces from the aem-nodetypes.jar provided in the plugin dependencies -->
                                    <cnds>tccl:aem.cnd</cnds>
                                </options>
                            </jackrabbit-nodetypes>
                        </validatorsSettings>
                    </configuration>
                    <dependencies>
                        <dependency>
                            <groupId>biz.netcentric.aem</groupId>
                            <artifactId>aem-nodetypes</artifactId>
                            <version>6.5.7.0</version>
                        </dependency>
                    </dependencies>
                </plugin>

I would say the nodetypes definition does not include this case.
