Question

我正在尝试使用Subversion作为使用Maven wagon的Maven仓库。如果我使用http作为协议声明快照位置，那么在尝试部署时会从服务器返回409错误（mvn clean deploy）

<snapshotRepository>
        <uniqueVersion>false</uniqueVersion>
        <id>engtools_snapshots</id>
        <name>EngTools Maven Repository</name>
        <url>http://continuum.td.com/svn_repos/maven/snapshots</url>
</snapshotRepository>

当我将协议更改为scm时：svn：http事情变得更加奇怪 - 我得到了几个看似与领域相关的错误

<snapshotRepository>
        <uniqueVersion>false</uniqueVersion>
        <id>engtools_snapshots</id>
        <name>EngTools Maven Repository</name>
        <url>scm:svn:http://continuum.td.com/svn_repos/maven/snapshots</url>
</snapshotRepository>

SCM配置

        <extensions>
        <extension>
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-scm</artifactId>
            <version>1.0-beta-6</version>
        </extension>
        <extension>
            <groupId>org.apache.maven.scm</groupId>
            <artifactId>maven-scm-manager-plexus</artifactId>
            <version>1.3-SNAPSHOT</version>
        </extension>
        <extension>
            <groupId>org.apache.maven.scm</groupId>
            <artifactId>maven-scm-provider-svnexe</artifactId>
            <version>1.3-SNAPSHOT</version>
        </extension>
    </extensions>

（mvn deploy）

Answer 1

如果你看看wagon-scm的POM，你会发现它依赖于1.0版本的maven-scm-provider- *工件。在您的扩展部分中，您引用了1.3-SNAPSHOT版本。

从版本1.2开始，AbstractCheckOutCommand的executeCheckOutCommand（）方法不再是抽象的，而是委托给另一个带有额外recursive参数的抽象方法。由于此更改，您会收到链接错误。

解决此问题的最简单方法是将maven-scm-provider- *扩展的版本更改为与wagon-scm所需的版本一致，即更改1.0或1.1版本的1.3-SNAPSHOT版本。

值得指出的是，我认为使用SCM系统来托管您的Maven存储库并不是一个好主意，特别是对于SNAPSHOT工件。相反，我建议使用repository manager，它们在托管工件的基础上提供了许多有用的功能。
