Andrew Purtell commented on PHOENIX-5022:
-----------------------------------------
[~elserj] [~tdsilva] Please consider raising a discussion on dev@hbase about
Java 7 and HBase 1.x. I'm going to cut branch-1.5 and make a release candidate
for 1.5.0 as soon as HBASE-21464 is in and 1.4.9 is out containing it. So,
before the end of this year. I think the occasion of a new minor release is a
good time to reevaluate our JRE/JDK support, and whether we need to bend to
current realities.
Although I think [~jamestaylor]'s suggestion is workable. I think you can set
the compiler configuration per module POM, try putting this in the POM for
phoenix-queryserver:
{code:java}
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>{code}

> Assignee: Josh Elser
> Priority: Blocker
> Fix For: 4.15.0

>
> It's likely been masked by frequent failures/flappers in phoenix-core, but
> we're (maybe) finally able to run all the tests successfully. Maybe a Java 8
> dependency snuck in again?
