jenkins - Protractor webdriver-manager takes forever to start Selenium -


i managed protractor tests running through jenkins build task on ci server, i'm having problem when run webdriver-manager start takes forever before selenium server starts.

eventually starts , console shows:

info - started socketlistener on 0.0.0.0:4444

but takes 5 minutes, whereas when try same on vagrant vm starts immediately.

i'm running headless protractor tests use xvfb-run run webdriver-manager start.

here's shell script use:

#!/bin/sh export display=:1  xvfb $display -ac -screen 0 1280x1024x8 & sleep 1  xvfb-run webdriver-manager start --standalone

this starts selenium server on vagrant vm, takes long time on ci server. here's output of script on ci server:

after minutes runs , can execute protractor tests, annoying , not suitable running tests on ci server.

on vagrant vm selenium server starts , output identical point:

both machines run ubuntu 14.04 kernel version , version of java different (see output), protractor version on ci server 2.1.0, on vm 1.8.0.

could problem or missing here?

the issue seems related source of randomness selenium using.

more info here: https://code.google.com/p/selenium/issues/detail?id=1301

tl;dr solution: append -djava.security.egd=file:///dev/urandom java command launches selenium. may have edit webdriver-manager's config.
