A control flow plugin that allows conditional execution within pipelines. The conditions are specified as expressions and the variables could include values specified as runtime arguments of the pipeline, token from plugins prior to the condition and global that includes global information about pipeline like stage, pipeline, logical start time and plugin.
Condition plugin specifies a boolean expression to be evaluated. During pipeline execution, the condition expression specified is evaluated resulting in boolean value (either true or false). Depending on the result of evaluation, either the downstream pipeline connected along true path is executed or along the false path is executed. At at point in time, only one path is executed.
