如何在另一个子模块中嵌入子Maven模块

Question

我想用Maven模块创建一个Spring项目。一个Maven模块需要包含在其他模块中，但这不起作用，并且会发生以下错误。

无法在项目GamesFrontend上执行目标：无法解析项目gamecreation：GamesFrontend的依赖项： jar：1.0-SNAPSHOT：找不到游戏创建：GamesBackend：jar：1.0.0 in https://oss.sonatype.org/content/repositories/springso urce-milestones已缓存在本地存储库中，直到springsource更新间隔才会重新尝试解析 -里程碑已过去或强制进行更新-> [帮助1]

应包含的模块的pom为：

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                </plugin>

    </build>
</project>    

应该在其中包含模块的pom如下所示：
