问题描述

我有一个使用 maven 管理的大型 java 项目。我们使用 Maven 3 进行管理(特别是 3.6.0)。

在项目中,有一个 sub=project 带有runtime-v5.pom.xml. 在说pom,有一个版本属性

<properties>
    <platform-v5.version>73.2.05</platform-v5.version>
</properties>

稍后在文件中使用

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.company.thing.platform</groupId>
            <artifactId>platform-parent</artifactId>
            <version>${platform-v5.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>com.company.release</groupId>
            <artifactId>platform-v5</artifactId>
            <version>${platform-v5.version}</version>
            <type>resolved-pom</type>
        </dependency>
    </dependencies>
</dependencyManagement>

我的目标是让 maven 引入最新版本的平台,我不想每次都更新这个文件中的版本。我认为将特定版本更改为范围将允许项目始终根据给定范围拉入最新版本。

platform-v5.version设置为特定的现有版本时,它构建得很好,但是当将版本设置为一个范围时[73.2.05,),例如

本质上,我想知道:为什么不能在maven依赖管理导入范围内提供版本范围?

解决方案


虽然版本范围并未完全弃用,但它们不再被视为最佳实践。现代方法是在构建之前运行适当的更新目标,以便 pom 中的版本号是可用的最新版本号。
