Here is the beginning of that script:

[ERROR] require 'rubygems'
[ERROR] env = { 'GEM_PATH' => [
[ERROR] '/Users/maxcom/git-checkout/lorsource/target/rubygems'
[ERROR] ] }
[ERROR] env['GEM_PATH'] += ENV['GEM_PATH'] unless ENV['GEM_PATH'].nil?
[ERROR] Gem.paths = env

Workaround: unset GEM_PATH before running mvn

[mprins]

So if you run into this problem on TravisCI do something like:

language: java
before_install:
  - unset GEM_PATH
before_script: 
  - mvn -e -Popenlayers
script: mvn -e -Pjenkins verify
jdk:
  - openjdk7

FYI, I've got a fix for this in pull request #53

[coreagile]

Until the pull request gets merged in, does anyone have a workaround for Heroku? I'm having trouble figuring out how to get it to unset the GEM_PATH env.

[coreagile]

The Heroku folks were super helpful, and sent me on a path of building a custom build pack. So here's one people can use:

When do you plan to make a release for 1.1.2 ?

[HoloRin]

+1. We'd also like to see a release since we currently are making do with unset GEM_PATH.
