Issue

• When using a Matrix (Multi-configuration) project with the Advanced Project Options > Restrict where this project can be run enabled, but no axis defined under the Configuration Matrix section, the build steps will run on any available agent.

Environment

• CloudBees Jenkins Enterprise (CJE)
• CloudBees Jenkins Enterprise - Managed Master (CJE-MM)
• CloudBees Jenkins Enterprise - Operations Center (CJE-OC)
• CloudBees Jenkins Team (CJT)
• CloudBees Jenkins Platform - Client Master (CJP-CM)
• CloudBees Jenkins Platform - Operations Center (CJP-OC)
• Jenkins LTS
• Matrix Project plugin

Resolution

The Multi-configuration project is designed to execute the build steps on the next available build agent if a Configuration Matrix > Slaves axis is not configured. The Advanced Project Options > Restrict where this project can be run only limits where the initial flyweight task may execute.

To configure where the build steps will run, configure a Slaves axis with the desired build agents. For example, the following configuration shows how to execute the build steps on two agents testNode1 and testNode2:
