Tasks do not run on agents due to Plugin availability errors
Problem
When using Remote agents, you may occasionally see Tasks fail with errors such as:
Error occurred while executing the build for <build name ###> (PROJ-PLAN-JOB-###) : Plugin <plugin key> not availableor:
Could not execute task '<task name>' no Plugin with key '<plugin key>' is installed.Diagnosis
If your <bamboo-agent-home>/atlassian-bamboo-agent.log has multiple JVM IDs running at the same time, this article applies. For example:

This is often caused by multiple Remote agents sharing the same Bamboo Agent Home directory. When new agents start up, the plugin cache within the agent home directory is cleared and reloaded from the server, which can cause these plugins to not be found by one of the agent processes.
Resolution
Please ensure that each Remote Agent has its own Home directory.
Create new Bamboo Agent Home directories so that every agent on the server has its own Home directory:
