原谅我的无知，因为我是maven的新手。我有一个远程存储库，我的项目pom用于从中下载依赖项。我的pom.xml的一般结构是这样的：

现在我知道如果我必须获得新版本的依赖项<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>MVNProject</groupId> <artifactId>MVNProject</artifactId> <version>0.0.1</version> <packaging>war</packaging> <dependency> <groupId>org.scala-lang.modules</groupId> <artifactId>scala-parser-combinators_2.11</artifactId> <version>1.0.1</version> </dependency> </dependencies> </project> ，我只需要指定新版本。像这样：

scala-parser-combinators

但我想做的是，在不对<dependency> <groupId>org.scala-lang.modules</groupId> <artifactId>scala-parser-combinators_2.11</artifactId> <version>1.0.1</version> </dependency> 进行任何更改的情况下，我想用我的远程存储库中的升级jar替换旧jar（我能够做到）。 / p>

所以我想知道的是，是否有一种方法可以在pom.xml中指定远程存储库中可用于特定工件的任何版本，即类似这样的东西（这只是一个猜）：

pom

非常感谢一些指导。

如果您使用 maven2 ，则在版本标记中使用最新或 RELEASE 值可以自动解决依赖项更新。虽然，此解决方案不适用于 maven3 （不推荐使用）。

如果您使用的是maven3，那么您必须稍微更新settings.xml。快照存储库将获得一个额外的 updatePolicy 标记。这样的事情： - 

<repositories>
    <repository>
        <id>you-snapshots</id>
        <url>http://host/nexus/repos/snapshots</url>
        <snapshots>
            <updatePolicy>always</updatePolicy>
        </snapshots>
        <releases>
            <updatePolicy>always</updatePolicy>
        </releases>
    </repository>
</repositories>

此外，Maven还有一个Versions插件，可让您将pom更新为可见存储库中最新的最新快照。它通过检查您的pom并与远程存储库进行比较然后根据需要进行修改来实现此目的。

这是一个有用的工具，但我肯定希望看到与已弃用的LATEST选项相当的东西。我发现这种依赖在持续集成场景中特别有用。

有些事情需要注意：

  • 您不应该从远程存储库中删除工件的特定发行版本并替换它，例如在远程存储库中使用1.0.1，删除它并再次在1.0.1下上载不同的工件。 Maven在本地存储库中缓存发布版本，因此您永远不会知道您获得了哪个工件。
  • 如果您有更新的版本，请为其提供更新的版本号（如1.0.2）。
  • 现在要走的路不是使用RELEASE或LATEST，而是使用版本插件更新依赖项（如$data = array_map(function($v) use ($keys) { return array_combine($keys, $v); }, $data); ）。
