I have a build set up using the Xcode plugin with a restriction set to run on an OSX build slave. The first build step in this job is to import the developer profile using the "Import Developer Profile" function. When I set it up this way, the first time I execute the build, the job launches and completes successfully. The second time I try to run this build, however, the job fails at the "import developer profile" step. The console log for the builds shows the following:

$ security list-keychains
$ security create-keychain -p ******** jenkins-iOS-Client-Dev
security: SecKeychainCreate jenkins-iOS-Client-Dev: A keychain with the same name already exists.
ERROR: Failed to create a keychain
Finished: FAILURE

If I manually run the 'security list-keychains' on the build slave as the build user (jenkins), I don't see any keychains listed:

$ sudo -u jenkins security list-keychains
Password:
"/Library/Keychains/System.keychain"

However, if I look in the Keychains directory for the 'jenkins' user on the OSX machine, I see a file named with the keychain:

$ pwd
/var/lib/jenkins/Library/Keychains
$ ls -l
total 176
rw-rr- 1 jenkins jenkins 37292 Mar 11 11:33 jenkins-iOS-Client-Dev
rw-rr- 1 jenkins jenkins 45164 Feb 21 17:30 login.keychain

This is a major issue for us as, without being able to import developer profiles dynamically in the job config, we have to go manually tweak the build environment to include the proper certs, mobileprofiles and credentials.
