Answer 1

Error : the hierarchy of the type "class name" is inconsistent error.

solution : class OtherDepJar {} --> is inside "other.dep.jar" .

class DepJar extends OtherDepJar {} --> is inside "dep.jar".

class ProblematicClass extends DepJar {} --> is inside current project .

If dep.jar is in the project's classpath, but other.dep.jar isn't in the project's classpath, Eclipse will show the" The hierarchy of the type ... is inconsistent error"
