配置好了maven环境，然后在eclipse中创建maven项目，添加依赖：
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.1.1</version>
</dependency>
pom文件报错：
Failure to transfer commons-logging:commons-logging:jar:1.1.1 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be
reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact commons-logging:commons-logging:jar:1.1.1 from/
to central (https://repo.maven.apache.org/maven2): The operation was cancelled. org.eclipse.aether.transfer.ArtifactTransferException: Failure to transfer commons-
logging:commons-logging:jar:1.1.1 from https://repo.maven.apache.org/maven2.........
问度娘了半天，没找到解决办法，最后看到有个人说common包是maven类库里的基本包，一开始就下载下来的，我就去看了下，发现本地maven类库中确实已经有了common-logging目录，在其中找到1.1.1版本的目录，发现commons-logging-1.1.1.jar.lastUpdated，正常jar包后面有个.lastUpdated后缀，我从官网下了个commons-logging-1.1.1.jar，替换了commons-logging-1.1.1.jar.lastUpdated，然后在eclipse中，选中项目-右击-maven-update project，ok 报错消失。
以后再遇到类似问题，先查看本地类库中有没有.lastUpdated后缀文件，记录一下，以后可以提醒自己。
