你如果想再maven中定义一些配置，这些配置需要整个团队遵守，比如定义maven版本，java版本，os配置，文件系统的配置，或者你想扩展的任何配置，那么就可以使用Maven Enforcer Plugin这个maven插件。
pom中引入Maven Enforcer Plugin插件。

在执行mvn clean package时会默认执行这个插件，如果只想运行这个插件可以直接mvn ,mvn ,mvn ,可以参考
比如我们如果想指定maven和java的版本，则配置如下：
-
-
[...]
-
-
-
-
org.apache.maven.plugins
-
maven-enforcer-plugin
-
1.0.1
-
-
-
enforce-versions
-
-
enforce
-
-
-
-
-
2.0.6
-
-
-
1.5
-
-
-
unix
-
-
-
-
-
-
-
-
-
[...]
如果为了提高执行速度，不想运行这个插件，则可以通过-Denforcer.skip=true或者简单的-Dskip=true就可以跳过这个这个插件的运行。如果mvn package过程中出现有关这个插件的异常，则可以简单通过这个参数跳过这个验证。
这个插件默认提供的规则有：
-
alwaysPass - Always passes... used to test plugin configuration.
-
alwaysFail - Always fail... used to test plugin configuration.
-
bannedDependencies - enforces that excluded dependencies aren't included.
-
bannedPlugins - enforces that excluded plugins aren't included.
-
dependencyConvergence - ensure all dependencies converge to the same version.
-
evaluateBeanshell - evaluates a beanshell script.
-
requireReleaseDeps - enforces that no snapshots are included as dependencies.
-
requireReleaseVersion - enforces that the artifact is not a snapshot.
-
requireMavenVersion - enforces the Maven version.
-
requireJavaVersion - enforces the JDK version.
-
requireOS - enforces the OS / CPU Archictecture.
-
requirePluginVersions - enforces that all plugins have a specified version.
-
requireProperty - enforces the existence and values of properties.
-
requireFilesDontExist - enforces that the list of files do not exist.
-
requireFilesExist - enforces that the list of files do exist.
-
requireFilesSize - enforces that the list of files exist and are within a certain size range.

当然你可以扩展自定义的规则：http://maven.apache.org/enforcer/enforcer-api/writing-a-custom-rule.html
