Question

我之前问了一个类似的问题，关于通过父pom继承依赖版本号的方法，我得到了那个部分。但是现在我看到了一个类似的POM，并且无法提供这些依赖项的版本号。如您所见，所有依赖项都没有指定版本号，父POM也没有提供这些版本号。

请帮助了解其工作原理。非常感谢。

Answer 1

在maven中，可以在<dependencyManagement>标记中管理依赖项版本。

在您的情况下，使用以下

管理版本

<dependency>
   <groupId>org.jboss.spec</groupId>
   <artifactId>jboss-javaee-7.0</artifactId>
   <version>${version.jboss.spec.javaee.7.0}</version>
   <type>pom</type>
   <scope>import</scope>
</dependency>

在上面的标记中，范围是导入，这意味着将导入pom，因此依赖项版本在org.jboss.spec：jboss-javaee-7.0工件中维护。它在标签上方的注释中提到。

REF：jboss-javaee-7.0-1.0.1.Final.pom

依赖项的版本号在哪里
