Unsupported major.minor 52.0

[FabioVCoelho]

Hi, i'm having the following problem:
When i use the .jar on hive with a jdk 1.8 the class com.lucidworks.hadoop.hive.LWStorageHandler send an error of minor.major, so, i changed my computer to use a jdk 1.8, than it works, but when i try to put some data in to the solr table, the class com/lucidworks/hadoop/hive/LWHiveInputFormat give me a error of Unsupported major.minor version 52.0, so either way some class will give me a error =/
I followed the readme step by step.

@FabioVCoelho The issue here is that you compile the hive-solr jar with java 1.8 and your hive cluster is running with java 1.7.

Please compile hive-solr again with java 1.7 and retry

To compile with java 1.7, please use the following commit:
f39cd7b

hive-solr in master was updated to Solr 6.x and it now only works with java 1.8

Hi, here is my java -version (java version "1.7.0_95"), so, I deleted the folder, and started all over again...
git init, git clone, git submodule init, git submodule update.
Then i changed the gradle.properties to:
-version=2.2.7 and solrVersion=5.5.2
then ./gradlew give me the following problem:
error: package java.time does not exist.
error: cannot find symbol.
and a lot of those. I'm not expert in git so, is there i way to pull this old version that u send me as commit?

here is the debug log, sorry i don't know how to put this in a better view, just code

Thank you for your time.
It's probably the same problem that the issue #34
