Steps to reproduce: ASSERT: Have OpenShift Enterprise connection ASSERT: Don't have Jenkins application on the given connection EXEC: Open wizard for new application EXEC: Choose some application type (doesn't matter which one) EXEC: Toggle checkbox next to jenkins cartridge EXEC: Click on "Apply" button Result: When I want to create new application with embedded jenkins-client cartridge or I want to embed jenkins-client cartridge to existings application I need separated Jenkins server application. There is a dialog (after toggle checkbox of jenkins-client cartridge) to create such application. After click on "Apply" button the process of creating started. Creation failed because there is not any "small" gear size. Probably in code is just value for "small" gear size used by default in this creation process. There should be some check what size of gears support the given openshift server and choose one of them. I think that this problem persist on every openshift server, which does not have gear "small".
