Add the ROC action "Check if artifact still exists physically "

Idea created by birma04 Employee on Jun 3, 2016

    We need to check if an artifact still exists physically. This test could be done at Pre-Init and Init stage to prevent a distribution failure.

    In the current situation, to check if an artifact exists physically we have two major choices:

    - retrieve it with "ROC - Get artifact" then delete it

    - depending of the artifact type (Nexus, local file,...), use actions to check the physical existence of the artifacts: sometimes, it require to introduce multiple server types in the process that are able to access physically to the artifacts


    The required ROC action could be the equivalent of " ROC - Get artifact" : we check the existence of the artifact but without its physical retrieval. It can be done from any server type.
