When we recently switched from gradle 2.9 to gradle 2.11 we started hitting intermittent build failures due to what appears to be issues connecting to our Artifactory repository server. We were forced to move back to 2.9 which appears to not have this issue. It’s totally possible that the Artifactory server is slow to respond as it tends to be a bit overloaded, however we do not see any of these issues in gradle 2.9 so I believe that release must have been more tolerant of whatever slowness or connection issues it is encountering with the server. Perhaps this is related to the update to HttpClient 4.4.1 in that release? The following is the stacktrace from the failed build:
FAILURE: Build failed with an exception.
