resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced

Maven在执行中报错：

- Failure to transfer org.slf4j:slf4j-api:jar:1.7.24 from http://localhost:8081/nexus/content/groups/public/ was cached in the local repository,
resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced.

原因是有些jar包没有完全下载下来，在编译中找不到jar包。

解决方法是在setting.xml中增加一个更新策略，如下：

<profiles>
<profile>
　　<id>nexus</id>
<!--所有请求均通过镜像 -->
<repositories>
<repository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled><updatePolicy>always</updatePolicy></releases>
<snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled><updatePolicy>always</updatePolicy></releases>
<snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>

<profile>
<id>jdk-1.7</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.7</jdk>
</activation>
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>
</properties>
</profile>
</profiles>
