Subject [jira] [Commented] (HADOOP-10530) Make hadoop trunk build on Java7+ only
Date Wed, 03 Dec 2014 21:43:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14233565#comment-14233565
] 

Andrew Wang commented on HADOOP-10530:
--------------------------------------

Do we need to update this too?

{code}
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-enforcer-plugin</artifactId>
          <version>1.3.1</version>
          <configuration>
            <rules>
              <requireMavenVersion>
                <version>[3.0.2,)</version>
              </requireMavenVersion>
              <requireJavaVersion>
                <version>1.6</version>
              </requireJavaVersion>
            </rules>
          </configuration>
        </plugin>
{code}

Also a small typo "such a" -> "such as".

This built fine for me locally with JDK7, so not sure what's up.
