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

Thanks for the reply.
I have used the f39cd7b commit and build but still failing with Java compatible issue.
Using java jdk1.7.0_80.

Error:

• What went wrong:
  Execution failed for task ':solr-hadoop-common:solr-hadoop-io:compileJava'.

Compilation failed; see the compiler error output for details

The problem is with the submodule.
You need to change it too.
use this commit for the solr-hadoop-common
lucidworks/solr-hadoop-common@b484c84
