maven之enforce插件

因为之前构建netty的时候maven一直报失败，打开pom看了下发现里面有个enforce的插件

maven的enforce插件会在构建的时候进行强制检查

 <plugin>
        <artifactId>maven-enforcer-plugin</artifactId>
        <version>1.1</version>
        <executions>
          <execution>
            <id>enforce-tools</id>
            <goals>
              <goal>enforce</goal>
            </goals>
            <configuration>
              <rules>
                <requireJavaVersion>
                  <!-- Enforce java 1.7 as minimum for compiling -->
                  <!-- This is needed because of java.util.zip.Deflater and NIO UDP multicast-->
                  <version>[1.7.0,)</version>
                </requireJavaVersion>
                <requireMavenVersion>
                  <version>[3.0.2,)</version>
                </requireMavenVersion>
              </rules>
            </configuration>
          </execution>
        </executions>
      </plugin>

 如上这段要求了JAVA版本必须是1.7且MAVEN版本必须在3.0.2以上

当不满足要求的时候会抛出异常阻断流程
