Instance Attribute Details

#inferred_plugins ⇒ Object (readonly)

This lists the plugins that was added automatically and not specified by the user.

When we encounter :type attribute with a source block, we add a plugin by name bundler-source-<type> to list of plugins to be installed.

These plugins are optional and are not installed when there is conflict with any other plugin.
