Troubleshooting

If you encounter a github acct/password issue then contact [email protected].

If you encounter a corporate proxy issue, you might need to set up your env vars as required by your IT department.

If you encounter a maven or artifactory account issue, add your predix.io username and encrypted password to a maven ~/.m2/settings.xml file on your laptop. It should be setup already if in a DevBox.

##Preparation Predix Microservice CF accesses code repos at https://github.com/PredixDev.

The best experience is to use a DevBox which has all the tools and settings pre-installed.

• In DevBox,

  • add your encrypted predix.io username and password to the ~/.m2/settings.xml by replacing [email protected] with your Predix.io user and pass.

  • to avoid entering user/pass several times, run this command to cache it

    git config --replace-all --global credential.helper 'cache --timeout=7200'
    

  • OSX: To enable Copy/Paste using Left Command key.

      On Host: Please choose VirtualBox/Preferences/Input/Virtual Machine/Host Key Combination.  
      Set to Right ⌘.  
      On VM: Choose System/Preference/Keyboard/Layouts/Layout Options/Alt/Win Key Behavior/Ctrl is mapped to Win Keys(and the usual Ctrl keys)
    

  We have a second DevBox for GE employees which helps with corporate proxy settings.

  In your own IT environment you may need to configure the proxy settings Environment variables within the VM or your own laptop.

• For non-DevBox users,
  For users wanting to install all the tools, please reference the DevBox settings, and also ensure you have the prerequisites installed from Predix.io Getting Started documentation and the RMD Reference App Dependencies.

  • add your encrypted predix.io username and password to the ~/.m2/settings.xml by replacing [email protected] with your Predix.io user and pass.

  • to avoid entering user/pass several times, run this command to cache it

    git config --global credential.helper cache --timeout=7200
