          Just hit the same problem after updating to the latest version of the Artifactory plugin

          Whatever the problem is, it looks like it was introduced in v2.9.0 of the Artifactory plugin. v2.8.2 does not exibit the error.

           

          And I'm running Jenkins core v1.642.4 btw in case that helps isolate the problem.

          Oh, and I re-ran my same test on a Jenkins 2 sandbox I have (core v2.46.1) and was unable to reproduce the error. My sandbox has the same plugins installed as our Jenkins 1 server but it has all the latest versions of them installed, so it's not quite a one-to-one comparison. However, perhaps the Jenkins core version is partially to blame for this problem as well.

          I am facing this issue in InfluxDB plugin as well.

          From the stacktrace, it looks like the issue is caused as a result of a dependency collision between two Jenkins plugins. One of the plugins uses an older version of Apache Http Client. Upgrading the client by the plugin should resolve the collision.

          eyalbe Is there a way to identify which plugin is causing this problem?

          eyalbe I had similar issue in InfluxDB plugin(https://issues.jenkins-ci.org/browse/JENKINS-44669). I have tried updating the library(httpcore) to latest version. Even then issue persists.
