无法访问 spring-boot-starter-parent 依赖项

问题描述

我正在使用 https://start.spring.io/ 创建 Spring Boot 项目，但在开发中我无法访问 spring boot starters 这些依赖项：

<dependency>
    <groupId>org.springframework.ws</groupId>
    <artifactId>spring-ws-support</artifactId>
        <version>3.0.10.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-oxm</artifactId>
        <version>5.3.2</version>
</dependency>

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
        <version>4.5.13</version>
</dependency>

<dependency>
    <groupId>com.sun.xml.messaging.saaj</groupId>
    <artifactId>saaj-impl</artifactId>
        <version>1.5.2</version>
</dependency>

我收到警告消息：

Overriding managed version 5.3.1 for spring-oxm
Overriding managed version 5.3.1 for spring-oxm
Duplicating managed version 4.5.13 for httpclient
Duplicating managed version 1.5.2 for saaj-impl

我已经搜索了如何修复它，有些人提到的一种解决方法是在 <!--$NO-MVN-MAN-VER$ --> 标记的末尾使用 </version> 来忽略警告。

我的问题是如何使这些（以及其他未来的依赖项）从 Spring Boot 中可见？

编辑 #1：pom.xml

</project>

解决方法

解决办法是去掉<version>...</version>，让Spring boot来处理版本。
