刚下载一个开源项目源码，用maven编译发现报错：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:1.4.1:enforce (enforce-versions) on project spark-parent_2.11: Some Enforcer rules
     have failed. Look above for specific messages explaining why the rule failed. -> [Help 1]
    [ERROR]
    [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
    [ERROR] Re-run Maven using the -X switch to enable full debug logging.
    [ERROR]
    [ERROR] For more information about the errors and possible solutions, please read the following articles:
    [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

根据报错提示信息得出是enforce插件检测规则失败，并且这里提供了一个官方解决连接，进入看看MojoExecutionException解释：

说明这个不是maven本身报错，而是它的插件报错了，并且告诉我们要去看一下插件的文档，提供了maven插件文档的链接，进入plugin index找到enforce插件，先看看这个插件是干什么的：

这里的对enforcer的解释是，这是做环境约束检查用，到pom.xml中找到对应的enforce插件：

<plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-enforcer-plugin</artifactId>
      <version>1.4.1</version>
      <executions>
        <execution>
          <id>enforce-versions</id>
          <goals>
            <goal>enforce</goal>
          </goals>
          <configuration>
            <rules>
              <requireMavenVersion>
                <version>${maven.version}</version>
              </requireMavenVersion>
              <requireJavaVersion>
                <version>${java.version}</version>
              </requireJavaVersion>
              <bannedDependencies>
                <excludes>
                  
                  <exclude>org.jboss.netty</exclude>
                  <exclude>org.codehaus.groovy</exclude>
                </excludes>
                <searchTransitive>true</searchTransitive>
              </bannedDependencies>
            </rules>
          </configuration>
        </execution>
      </executions>
    </plugin>

这里对java.version和maven.version做了约束，把配置改成本地对应的版本号即可。
