MettleCI CLI produces error 'The SSL certificate must have previously been accepted in order to connect'

Problem

In this example the following mettleci datastage deploy command…

CODE

C:\> mettleci datastage deploy ^
     -domain iis-server.mycorp.com:9446 -server iis-server.mycorp.com ^
     -project myproject_ci ^
     -username isadmin -password **** ^
     -assets C:/jenkins-agent/workspace/MettleCI/datastage/Jobs/MettleCI -project-cache C:/MettleCI/cache/iis-server/myproject_ci

…works well until it gets to the compilation step at which point each job produces this error:

CODE

 * Compile 'iis-server.ibm.demo/dstage1_ci/Jobs/MettleCI/mci_test_base_vlo1.pjb' - FAILED
      
      Initializing
      
      Failed to attach to the project.
      The SSL certificate must have previously been accepted in order to connect to server https://iis-server.ibm.demo:9446.

      Exit Status 1

Solution

Surprisingly, the solution to The SSL certificate must have previously been accepted in order to connect is to ensure you have accepted your SSL certificate.

In summary

Ensure your DataStage environment is properly installed, configured, and functional before using the MettleCI CLI. In particular ensure your istool and dscc commands behave correctly.
