把这个加到pom.xml中去

apache.snapshots
Apache Snapshots
http://repository.apache.org/content/groups/snapshots-group/

false

true

解决方案二：

apache.snapshots
Apache Snapshots
http://repository.apache.org/content/groups/snapshots-group/

解决方案三：

 <pluginRepositories>
    <pluginRepository>
        <id>apache.snapshots</id>
        <name>Apache Snapshots</name>
        <url>http://repository.apache.org/content/groups/snapshots-group/</url>
        <releases>
            <enabled>false</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
