Eclipse: Maven проект строитель генерация NullPointerException при создании рабочего пространства

Question

Я использую STS со следующей информацией версии

Spring Tool Suite 
Version: 3.7.0.RELEASE 
Build Id: 201506290652 
Platform: Eclipse Mars (4.5.0) 

я импортировал ряд проектов Maven. Когда Eclipse, автоматически строить свое рабочее пространство, это появится диалоговое окно

Errors occurred during the build. 
Errors running builder 'Maven Project Builder' on project 'myproject'. 
java.lang.NullPointerException 

Когда я смотрю в моем рабочем пространстве/.metadata/.log файл, я вижу

!ENTRY org.eclipse.core.resources 4 75 2015-07-28 08:40:07.418 
!MESSAGE Errors occurred during the build. 
!SUBENTRY 1 org.eclipse.m2e.core 4 75 2015-07-28 08:40:07.418

Я понятия не имею, что это значит или как его исправить. Справка оценивается, - Dave

Удаление .settings Папка и реимпорт-проект Maven решили мою проблему.
