无法在本地找到元数据

Question

在机器本地我有一个与maven存储库一起安装的Artifactory,我有一个非常简单的.pom文件,我的项目指向它:

<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/maven-v4_0_0.xsd">

        <sourceDirectory>SRCFOLDER</sourceDirectory>
        <testSourceDirectory>TESTFOLDER</testSourceDirectory>

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                </configuration>
            </plugin>
        </plugins>

    </build>

    <repositories>
        <repository>
            <id>local-artifactory</id>
            <name>Artifactory</name>
            <url>http://localhost:8081/artifactory/repo</url>
            <layout>default</layout>
            <releases>
                <enabled>true</enabled>
                <updatePolicy>always</updatePolicy>
                <checksumPolicy>warn</checksumPolicy>
            </releases>
            <snapshots>
                <enabled>true</enabled>
                <updatePolicy>always</updatePolicy>
                <checksumPolicy>warn</checksumPolicy>
            </snapshots>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>local-artifactory-plugins</id>
            <name>Artifactory Plugins</name>
            <url>http://localhost:8081/artifactory/repo</url>
        </pluginRepository>
    </pluginRepositories>

<dependencies>
    <dependency>
        <groupId>MYGROUP</groupId>
        <artifactId>DEPENDENCY1</artifactId>
        <version>bla-SNAPSHOT</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>MYGROUP</groupId>
        <artifactId>DEPENDENCY2</artifactId>
        <version>bla-SNAPSHOT</version>
        <scope>compile</scope>
    </dependency>
</dependencies>
</project>

所以我声明了本地神器库,意图是每次都会重新加载所有内容.此外,我有几个依赖,这是快照.

现在我正在使用maven 3.0.5,当我正在编译它时它工作正常,但它根本不是刷新快照.决不.永远.日志文件如下所示:

[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.

所以它经常抱怨它找不到本地maven-medatada.xml,当然他完全正确 - 它不在那里.并没有做任何事情.

所以我试图使用依赖:purge-local-repository来清除本地库存并猜测是什么？显然它无法清除它,因为每个工件中都没有maven-metadata.xml,这真是一个了不起的功能!

除.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artifactory,current的maven-metadata.xml的正确副本),_ make.repositories和resolver-status.properties.

Maven是开箱即用的,.m2中没有配置,并且/ conf文件夹中的配置是默认的,没有任何单一更改.

更新:我只是从工件中手动下载了maven-metadata.xml,并将其作为maven-metadata.xml放在.m2中作为​​依赖项 - 没有效果,它仍然"缺失"它.所以我不知道它对我的要求了.它只是无法更新依赖项,因为"已在此会话期间更新".好吧,我不知道它究竟更新了什么,但显然还有别的东西.

UPDATE2:服务器上maven-metadata.xml的内容:

<metadata>
    <groupId>MYGROUP</groupId> 
    <artifactId>DEPENDENCY1</artifactId> 
    <version>bla-SNAPSHOT</version> 
    <versioning>
        <snapshot>
            <buildNumber>1</buildNumber> 
        </snapshot>
        <lastUpdated>20130322155759</lastUpdated> 
    </versioning>
</metadata>

Answer 1

我的maven抱怨它找不到本地的元数据,等等......基本上,发生的事情是我设法拔掉我在maven-build中的电源线,并且它在相关的本地.m2子目录中的元数据被破坏了.我进去了,从他们的.m2位置删除了有问题的工件并重新尝试了构建.一切正常.只是想留给那些与我有类似问题的人留言,但偶然发现了你的问题.

Answer 2

从maven元数据xml文件看起来,您在存储库中使用非唯一快照.Maven 3不支持使用TIMESTAMP-BUILDNUMBER而非SNAPSHOT的非唯一,仅快照pom文件.你有没有:

http://localhost:8081/artifactory/repo/MYGROUP/DEPENDENCY1/bla-SNAPSHOT/DEPENDENCY1-bla-XXXXX-Y.pom

文件？
