Maven:为什么工件文件名中缺少-SNAPSHOT后缀? [英] Maven: Why is the -SNAPSHOT suffix missing from artifact file name?

问题描述

我的maven工件已部署到Nexus快照存储库.在那里，它存储在正确的目录中，但是其文件名具有以下模式:

My maven artifact is deployed to a Nexus snapshot repository. There, it is stored in the correct directory, but its filenames have the following pattern:

mylibrary-1.0-20130213.125827-2.jar

但是，Maven无法下载该快照.根据错误日志，Maven似乎期望使用以下文件名:

However, Maven fails to download that snapshot. According to the error log, Maven seems to expect the following file name:

mylibrary-1.0-SNAPSHOT.jar

这些是我pom中的存储库设置:

These are the repository settings in my pom:

<repositories>
    <repository>
        <id>mycompany-all</id>
        <url>https://servername/nexus/content/groups/mycompany/</url>
    </repository>
</repositories>

<distributionManagement>
    <repository>
        <id>mycompany-releases</id>
        <url>https://servername/nexus/content/repositories/releases/</url>
    </repository>
    <snapshotRepository>
        <id>mycompany-snapshots</id>
        <url>https://servername/nexus/content/repositories/snapshots/</url>
    </snapshotRepository>
</distributionManagement>

注意:链接组同时包含releases和snapshots存储库.

Note: the nexus group includes both the releases and snapshots repo.

我没有在settings.xml中配置这些存储库-这是问题吗?还是我做错了什么?

I did not configure these repos in settings.xml - is that the problem? Or what else am I doing wrong?

推荐答案

我通过将存储库添加到settings.xml来使其工作，如下所示:

I made it work by adding the repositories to the settings.xml like this:

<repositories>
    <repository>
        <id>mycompany-releases</id>
        <url>https://servername/nexus/content/repositories/releases/</url>
        <releases><enabled>true</enabled></releases>
        <snapshots><enabled>false</enabled></snapshots>
    </repository>
    <repository>
        <id>mycompany-snapshots</id>
        <url>https://servername/nexus/content/repositories/snapshots/</url>
        <releases><enabled>false</enabled></releases>
        <snapshots><enabled>true</enabled></snapshots>
    </repository>
</repositories>

然后，就可以下载SNAPSHOT jar文件了.我怀疑当Maven知道它处理快照回购时，无论是否使用uniqueVersion，它都会尝试(请参阅Duncan Jones的回答).

Then, the SNAPSHOT jar files were downloaded just fine. I suspect that when Maven knows it deals with a snapshot repo, it tries both with and without uniqueVersion (see Duncan Jones' answer).

请注意，在我们的情况下，由于我们具有自定义的Maven插件，因此必须将这些块复制为pluginRepositories.

Note that in our case these blocks had to be duplicated as pluginRepositories because we have custom Maven plugins.
