在本地找不到元数据

在本地机器上，我安装了带有Maven存储库的Artifactory，并且我的项目有一个非常简单的.pom文件，指向该文件:

Locally on the machine i have an Artifactory installed with maven repositories, and i have a very simple .pom file for my project which points to it:

所以我声明了本地人工存储库，目的是每次都会重新加载所有内容.我也有几个依赖关系，即快照.

So i have local-artifactory repository declared with the intention that it will reload everything every time. Also i have couple of dependencies which are SNAPSHOTS.

现在我正在使用maven 3.0.5，并且在我对其进行编译时，它可以正常工作，但它根本不刷新快照.绝不.曾经.日志文件如下所示:

Now i'm using maven 3.0.5, and when i'm compiling it it works fine, but it's not refreshing snapshots at all. Never. Ever. Log file looks like this:

[DEBUG] Could not find metadata MYGROUP:DEPENDENCY1:bla-SNAPSHOT/maven-metadata.xml in local (/opt/myuser/.m2/repository)
[DEBUG] Using connector WagonRepositoryConnector with priority 0 for http://localhost:8081/artifactory/repo
Downloading: http://localhost:8081/artifactory/repo/MYGROUP/DEPENDENCY1/bla-SNAPSHOT/maven-metadata.xml
Downloaded: http://localhost:8081/artifactory/repo/MYGROUP/DEPENDENCY1/bla-SNAPSHOT/maven-metadata.xml (314 B at 13.9 KB/sec)
[DEBUG] Writing resolution tracking file /opt/myuser/.m2/repository/MYGROUP/DEPENDENCY1/bla-SNAPSHOT/resolver-status.properties
[DEBUG] Could not find metadata MYGROUP:DEPENDENCY1:bla-SNAPSHOT/maven-metadata.xml in local (/opt/myuser/.m2/repository)
[DEBUG] Skipped remote update check for MYGROUP:DEPENDENCY1:bla-SNAPSHOT/maven-metadata.xml, already updated during this session.

因此，它一直抱怨它找不到本地maven-medatada.xml，当然他是完全正确的-它不存在.却无能为力.

So it constantly complains that it can't find local maven-medatada.xml and of course he's completely right - it's not there. And fails to do ANYTHING with it.

因此，我尝试使用dependency:purge-local-repository清除本地库存并猜测是什么?显然它不能清除它，因为每个工件中都没有maven-metadata.xml，这真是一个了不起的功能！

So i've tried to use dependency:purge-local-repository to purge local inventory and guess what? Apparently it can't purge it because there is no maven-metadata.xml in each artifact, what an amazing functionality!

除了.jar和.pom之外的每个.m2工件目录都包含maven-metadata-local-artifactory.xml(具有来自工件(当前)的maven-metadata.xml的正确副本)，_mave.repositories和resolver-status .properties.

Each .m2 artifact directory apart of .jar and .pom contains maven-metadata-local-artifactory.xml(with the correct copy of maven-metadata.xml from the artifactory, current), _mave.repositories and resolver-status.properties.

Maven是开箱即用的，.m2中没有配置，/conf文件夹中的配置是默认设置，没有任何更改.

Maven is just out of the box, there is no configuration in .m2 and the configuration in the /conf folder is default without any single change.

更新:我刚刚从工件上手动下载了maven-metadata.xml并将其作为.m2内的maven-metadata.xml进行了依赖-无效，它仍然在丢失"它.所以我不知道它要我什么了.它只是无法更新依赖项，因为已在此会话中更新".好吧，我不知道它究竟更新了什么，但是显然还有其他东西.

UPDATE: I've just manually downloaded maven-metadata.xml from the artifactory and placed it as maven-metadata.xml inside .m2 for a dependency - no effect, it is still "missing" it. So i don't have any idea what it wants from me anymore. It just can't update dependencies because "already updated during this session". Well i don't know what it updated exactly, but apparently something else.

UPDATE2:服务器上maven-metadata.xml的内容:

UPDATE2: Contents of maven-metadata.xml on the server:
