[jira] [Commented] (PARQUET-342) Can't build Parquet on Java 6

["Alex Levenson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PARQUET-342?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14639964#comment-14639964 ] 

Alex Levenson commented on PARQUET-342:
---------------------------------------

Thanks for the fixes. I think this opens up the discussion of: do we need to / want to continue supporting java 6 in parquet? 
That might be worth starting a thread on the mailing list about.

> I am having problems building the latest master with Java 6. I tried building the whole project 
> {noformat}mvn clean install -DskipTests{noformat}
>  and I also tried building individual modules 
> {noformat}mvn --projects parquet-common -am -amd -U clean install -DskipTests{noformat}
> Both fail with the same error shown below. SemanticVersion class uses Integer.compare(int,int) which was introduced in Java 1.7, but, AFAIK and according to the pom file (and to PARQUET-146) Parquet should still be built using Java 6. Similarly TestInputOutputFormatWithPadding and TestInputOutputFormat classes depend on java.nio.file package that was introduced in Java 1.7
> When I switch over to Java 7 the build succeeds.
