Steps to Reproduce
- Log on to Pega.
- Open any application.
- Go to the Mobile Tab.
- Fill in the values for "Unique application identifier", "Description" and "Release version:"
- Add and Select "Distribution P12 file"
- Click Create Build button.
- Notice the Build finishes with 100% and displays downloading and it hangs there.
Root Cause
From September 2016 onwards, the build Server operates via SSL only. Production Build Server uses certificate issued by Go Daddy - in order to establish connection with it, Java trust store (cacerts) on Pega server needs to contain entry for Go Daddy Root CA. CN = Go Daddy Root Certificate Authority - G2 O = GoDaddy.com, Inc. L = Scottsdale S = Arizona C = US
Resolution
Perform the following local-change:
To delete the hanged mobile build, Create and run an activity that does Obj-Delete-By-Handle in order to remove a stuck mobile build. The handle would be like this
DATA-MOBILE-BUILD RULE-APPLICATION <ApplicationName> <ApplicationVersion>!PRPC-HYBRID-<ANDROID/IOS>
For e.g.
ATA-MOBILE-BUILD RULE-APPLICATION MYAPP 01.01.01!PRPC-HYBRID-ANDROID)
Make sure to check the 'Immediate' checkbox with Obj-Delete-By-Handle.
In this case my application name is "MYAPP" and version is "01.01.01" . You can also view the column "PZINSKEY" of the Database table "PR_DATA_MOBILE_BUILD" for the handle
Run the activity To delete the hanged mobile build.
Next step is to import the Pega Mobile build server certificates.
Download the certificates from the Pega Mobile buildserver URL https://mobilebuildserver.pega.com/buildserver
Import the certificates in the application server truststore and restart the application server.
