Проблемы зависимости с Eclipse и мультимодульным проектом Maven

Question

У меня есть многомодульный проект maven, состоящий из трех субмодулей: web , service и domain . Я использую m2e и мне удалось импортировать maven проекты в Eclipse.

Более того, сервис и домен находятся в пути сборки Java web , а domain - в проекте путь сборки Java .

Это очень странно, потому что отображаются ошибки компиляции, которые, кажется, указывают, что, например, service не видит domain . Однако, когда я нажимаю на класс по ошибке в затмении, я могу перейти к классу domain .

Кроме того, я могу добавить проект web к экземпляру сервера Tomcat, но проект web не содержит два других проекта.

Может кто-нибудь помочь, пожалуйста?

Answer 1

Определить домен и служебные модули внутри тега управления зависимостями в Super Pom. Поэтому, в основном, добавьте следующее определение внутри супер-помпа:

     <dependencyManagement>
        <dependencies>
           <dependency>
              <groupId>com.bignibou</groupId>
              <artifactId>bignibou-domain</artifactId>
              <version>1.0-SNAPSHOT</version>
           </dependency>
           <dependency>
              <groupId>com.bignibou</groupId>
              <artifactId>bignibou-service</artifactId>
              <version>1.0-SNAPSHOT</version>
           </dependency>
        <dependencies>
     </dependencyManagement>

После добавления этих определений в супер-помпу, у вас также будет возможность удалить номера версий для этих зависимостей из модуля pom.

Answer 2

Вы не должны работать с путями построения затмений.

Добавьте службу и домен в зависимости от pom.xml. Добавьте домен в pom.xml из вашего сервиса.

После правильной настройки зависимостей m2e правильно настроит пути сборки.
