Currently, when building from a basic pom.xml:
many plugins are used, but their version is not locked by the user: the default plugins versions depend on Maven version used, which is not stable over different Maven versions.
Adding a warning for this stability issue will help users know that they need to lock down plugins versions in their pom (or parent), something like:
[WARNING] Some problems were encountered while building the effective model for com.mycompany.app:my-app:jar:1.0-SNAPSHOT
[WARNING] Version not locked for default bindings plugins [maven-install-plugin, maven-resources-plugin, maven-surefire-plugin, maven-compiler-plugin, maven-jar-plugin, maven-deploy-plugin, maven-site-plugin], you should define versions in pluginManagement section of your pom.xml or parent
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.
