The bamboo-specs and bamboo-specs-api libraries are missing from MettleCI CLI’s lib folder
The version of bamboo-specs and / or bamboo-specs-api in MettleCI CLI’s lib folder is incorrect for the version of Bamboo you are working with.

Solutions

Identify the version of Bamboo you are using. The bamboo-specs and bamboo-specs-api must match the version of bamboo you are using
Follow the instructions in the Prerequisites section of this page to download and install the required version of bamboo-specs and bamboo-specs-api .
