在Maven包之后，战争出现重复罐子，但在Maven包之前不会重复

Question

"hibernate-entitymanager-4.2.5.Final.jar"在maven中的maven包之前没有冲突，如下图所示 在此处输入图像描述

但是在 Maven 包之后，有 2 个"休眠实体管理"罐子，如下图所示。 在此处输入图像描述

它导致项目失败，但删除"休眠-实体管理器-4.3.10.Final.jar"后成功

但我想弄清楚 maven 包添加另一个"休眠实体"jar 的原因。

Answer 1

您可以运行以下 maven 目标。

mvn dependency:tree -Dverbose -Dincludes=hibernate-entitymanager

它应该给出依赖冲突。 然后，您可以排除不想包含的版本，如下所示

<dependencies>
<dependency>
<groupId>sample.ProjectA</groupId>
<artifactId>Project-A</artifactId>
<version>1.0</version>
<scope>compile</scope>
<exclusions>
<exclusion>  <!-- declare the exclusion here -->
<groupId>sample.ProjectB</groupId>
<artifactId>Project-B</artifactId>
</exclusion>
</exclusions> 
</dependency>
</dependencies>
