Question

我很难过。我正在使用ant和maven-ant-tasks来构建和部署快照工件（非maven）到远程nexus存储库。构建过程指定存储库的URL。这是运行的蚂蚁目标：

<target name="shared_resources_war_deploy" depends="shared_resources_war">
    <artifact:pom id="sharedResourcesPom" file="${resourcesdir}/shared-resources-pom.xml" />
    <echo message="**************************${nexus.url}*************************" />
    <artifact:deploy file="${resourcesdir}/shared-resources.war">
        <remoteRepository url="${nexus.url}">
            <authentication username="${nexusUserName}" password="${nexusUserPassword}" /> 
        </remoteRepository>
        <pom refid="sharedResourcesPom"/>
    </artifact:deploy>
</target>

结果：

shared_resources_war_deploy:
     [echo] **************************http://${nexusIP}:8081/nexus/content/repositories/snapshots*************************

由于某种原因，我不了解，maven正在尝试部署到公共存储库（nexus不允许）而不是指定的快照存储库（请注意nexus.url变量）。否则构建文件中的位置是指定的公共URL。

为了让事情变得更好奇，在一台机器上，相同的构建脚本成功部署了具有此结果的相同工件：

shared_resources_war_deploy:
     [echo] **************************http://${nexusIP}:8081/nexus/content/repositories/snapshots*************************
[artifact:deploy] Deploying to http://${nexusIP}:8081/nexus/content/repositories/snapshots

BUILD SUCCESSFUL

实际使用指定的URL。在比较两台机器时，ant（版本1.8.1）和maven-ant-tasks（2.1.3）都是相同的版本。 nexus日志表明两者之间的传入请求不同（其中一个指定快照存储库，另一个指定公共存储库）所以我想在Maven上固定此错误。但是，我无法确定导致此问题的任何差异。

发生了什么事？？

更新

在嗅探数据包之后，我们发现来自maven的请求被发送到：/nexus/content/groups/public/com/xactsites/shared-resources/13.1.19.2/shared-resources-13.1.19.2.war HTTP /1.1，确认maven在发送请求之前正在更改URL。因此，解决这个问题的任何努力都可以集中在maven（而不是nexus）上。

Answer 1

经过一些痛苦的研究和一位同事的侥幸错字开辟了探索的新途径，我们找到了原因。基本上，如果M2 / M2_HOME环境变量设置为指定的here，则远程存储库URL将被我们的settings.xml文件覆盖，并使用为nexus设置的镜像（因此使用了错误的，部署的只读URL。

这似乎是使用<distributionManagement>元素在pom中以及在ant文件中使用<remoteRepository>元素的问题。已经a bug filed for this了。

<强>分辨率：

我们将<mirrorOf>*</mirrorOf>设置为“*”导致此问题的范围缩小了。用特定存储库（例如“central”）替换*可以解决此问题。

同样，不设置M2环境变量也会修复此问题，因为它无法访问settings.xml文件来获取URL。当然，如果您在运行部署时依赖settings.xml中的其他一些内容，则不希望采用这种方法。

uggh，这是一个很难追踪的错误。

Answer 2

这似乎在2.1.4-SNAPSHOT版本中得到解决。

Maven ant任务部署到公共nexus存储库而不是指定的url
