The following problems are reported:

• Unresolved component/action implementation-classes (plugin.xml)
• Unresolved component interface-classes (plugin.xml)
• Component implementation-class is not assignable to its interface-class (plugin.xml)
• Incorrect component registration, e.g. ProjectComponent is registered as Application Component, or the class doesn't implement any component interface at all (plugin.xml and Java code)
• Incorrect class modifiers: Action classes must be public and must have a public no-argument constructor. Additionally, Action and Component implementation classes must not be abstract (plugin.xml and Java code)
• Duplicate interface-class: A class may only be used once as interface-class (plugin.xml)

Configure the inspection:

• Use the Check Plugin Descriptor (plugin.xml) option to disable checks in plugin.xml descriptor.
• Use the Check Java Actions option to disable checks in Action code.
• Use the Check Java Code option to disable all checks in code.
