#### Checkstyle

If you have the [Checkstyle] plugin installed, you can configure IntelliJ to
check the Elasticsearch code. However, the Checkstyle configuration file does
not work by default with the IntelliJ plugin, so instead an IDE-specific config

plugin, so following best practices is relatively straightforward.  For core plugins in gradle/gradle, it's easy for an object to be created without applying its associated plugin. For instance, Spring has a plugin that uses the Checkstyle task directly without applying the Checkstyle plugin.

Until we can provide the same guarantees for core plugins, we need to be more conservative for existing classes and not follow best practices. This means conventions need to be set in both a plugin and the...
