由于MapR工件问题，无法从源代码构建Flink

摘要：找不到mapr依赖性，因此在master分支上构建的Flink失败。 

Failed to execute goal on project flink-mapr-fs: Could not resolve 
dependencies for project org.apache.flink:flink-mapr-fs:jar:1.10-SNAPSHOT: 
Failed to collect dependencies at com.mapr.hadoop:maprfs:jar:5.2.1-mapr

MapR作为一家公司一直在进行停产谈判-我不清楚他们是否公开营业。答案是什么/在这里做什么？我想简单地“跳过” /忽略映射器连接器，但不确定如何执行此操作。

只需验证您在“ flink / flink-filesystems / flink-mapr-fs / pom.xml”中具有以下条目

<profile>
    <id>unsafe-mapr-repo</id>
    <activation>
            <property>
                    <name>unsafe-mapr-repo</name>
            </property>
    </activation>
    <repositories>
        <!-- MapR -->
        <repository>
                <id>mapr-releases</id>              
                <url>http://repository.mapr.com/maven/</url>                                
                <snapshots><enabled>false</enabled></snapshots>                             
                <releases><enabled>true</enabled></releases>
        </repository>
    </repositories>
</profile>

一旦通过验证，请从“ flink / flink-filesystems / flink-mapr-fs”运行以下命令，以确保以下项目的构建成功。 mvn clean package -DskipTests -Punsafe-mapr-repo。 成功完成后，请从“ flink / flink-filesystems”运行相同的maven软件包命令，以确保构建成功，然后从flink项目运行应该会很好。 这将确保您成功完成flink项目的目标构建。
