Maven Enforcer Plugin 定义一些必须遵守的配置

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。

 

 

<project>
  ...
  <build>
    <!-- To define the plugin version in your parent POM -->
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-enforcer-plugin</artifactId>
          <version>1.0.1</version>
        </plugin>
        ...
      </plugins>
    </pluginManagement>
    <!-- To use the plugin goals in your POM or parent POM -->
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-enforcer-plugin</artifactId>
        <version>1.0.1</version>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

 

 

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 enforcer:display-info,mvn enforcer:enforce,mvn ,可以参考http://maven.apache.org/plugins/maven-enforcer-plugin/plugin-info.html

 

比如我们如果想指定maven和java的版本，则配置如下：

 

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-enforcer-plugin</artifactId>
        <version>1.0.1</version>
        <executions>
          <execution>
            <id>enforce-versions</id>
            <goals>
              <goal>enforce</goal>
            </goals>
            <configuration>
              <rules>
                <requireMavenVersion>
                  <version>2.0.6</version>
                </requireMavenVersion>
                <requireJavaVersion>
                  <version>1.5</version>
                </requireJavaVersion>
                <requireOS>
                  <family>unix</family>
                </requireOS>
              </rules>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]

 

 

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
