Answer 1

16386 is the index in the array. The problem is that the array is not as big as 16386. (i.e. size of the array < 16387)

Anyway, it won't help you to solve this problem.

You can check that your pom.xml contains this (and that it is valid):

<?xml version="1.0" encoding="UTF-8" ?>

EDIT

Your problem is certainly a local problem. So first check the validity of your maven config files:

• .m2/settings.xml
• M2_HOME/conf/settings.xml

If these look fine, then the problem may also be caused by a "corrupt" (bad XML) pom.xml ANYWHERE in your local repo... the easiest workaround is to just wipe your ~/.m2/repository, to let Maven re-download everything.

Answer 2

I wiped my ~/.m2/ folder and then re-ran and Maven re-downloaded everything - worked for me!
