I'm trying to install the Jenkins workflow plugin into a Jenkins 1.641 installation. I have downloaded the latest version of the plugin (v1.12 - https://wiki.jenkins-ci.org/display/JENKINS/Workflow+Plugin). On trying to upload and install, I get this error:-

Can anyone suggest the cause of the problem?

You have to install Pipeline (formerly known as Workflow) 1.13 (or Workflow Aggregator 1.12 if you want 1.12 instead of 1.13) from the update center, don't try to install it manually (or you would have to install all the dependencies manually, as pointed in the log: Dependency workflow-basic-steps (1.12), workflow-scm-step (1.12), workflow-cps-global-lib (1.12), workflow-support (1.12), workflow-job (1.12), workflow-durable-task-step (1.12), workflow-cps (1.12), workflow-api (1.12), workflow-step-api (1.12) doesn't exist)

The cause of the Problem is, that workflow-aggregator is only one piece of the workflow and is depending on other plugin parts.

The Other parts are found here :

Caused by: java.io.IOException: Dependency workflow-basic-steps (1.12), workflow-scm-step (1.12), workflow-cps-global-lib (1.12), workflow-support (1.12), workflow-job (1.12), workflow-durable-task-step (1.12), workflow-cps (1.12), workflow-api (1.12), workflow-step-api (1.12) doesn't exist

The easy solution is to use the update center as suggested by amuniz.

If you develop in an regulated environment and need more control over installed plugins or need a reproducible environment, download all dependent plugins.

I didnt find a link on the workflow parts (the dependencys link to the same page), so you may work around that problem by using a download url of following patern:

updates.jenkins-ci.org/latest/<plugin-name>.hpi

Example:

updates.jenkins-ci.org/latest/workflow-step-api.hpi

Or if you need a special revision of the plugin use:

http://updates.jenkins-ci.org/download/plugins/<plugin-name>/<revision>/<plugin-name>.hpi

Example :

http://updates.jenkins-ci.org/download/plugins/workflow-step-api/1.12/workflow-step-api.hpi
