maven - Jenkins Failed to Parse POMs: Permission Denied -

i have been having issues getting new openshift jenkins ci server work. setup way tutorials tell me to, when try build project, same error:

i using maven 3.3.9 , have made sure permissions correct. fresh install of openshift jenkins changes being adding jdk 7u79, github plugin (including updating dependencies it) , adding maven 3.3.9, denied permission pom making unable read.

i have seen question openshif jenkins: java.net.bindexception: permission denied link provided in answer outdated , no longer present, redirecting me documentation not help.

how can allow jenkins server permission allow parse pom file , build code?

check jenkins configuration :

1. scm plugins
2. jenkins->configure system
