Hi Guys I found that the develop branch can only be built by java 8 which is inconvenience for community. Here is the discuss for end supporting for java 7 in spark 2.0 <http://apache-spark-developers-list.1001551.n3.nabble.com/discuss-ending-support-for-Java-7-in-Spark-2-0-td16808.html#a16810>, however the 2.0 preview version still support it.
I think eagle should support both java 7 and 8 for one year, the reason is obvious, most company are still using java 7 and need schedule to upgrade java 8 for at least six or nine month Thanks Chang
