### Build tree state

"Build tree" is another name for the build definition.
The "build tree state" holds the state for the entire build definition for a single build execution within a session.

The build tree state is managed by the `BuildTreeState` class.
An instance is created at the start of a build execution and discarded at the end of the execution.

### Build state

            include("**/reaper.log")
            include("**/build/test-results/**/*.xml")
            include("**/build/testclusters/**")
            exclude("**/build/testclusters/**/data/**")
            exclude("**/build/testclusters/**/distro/**")
            exclude("**/build/testclusters/**/repo/**")
            exclude("**/build/testclusters/**/extract/**")
          }
            .files

        }
      } else {
        tag jobName
        value 'Job Name', jobName
      }

      tag 'CI'
      link 'CI Build', buildUrl
      link 'GCP Upload', "https://console.cloud.google.com/storage/browser/_details/elasticsearch-ci-artifacts/jobs/${URLEncoder.encode(jobName, "UTF-8")}/build/${buildNumber}.tar.bz2"
      value 'Job Number', buildNumber
      if (jobBranch) {
        tag jobBranch

# Build execution model

At the highest level, Gradle's execution model is quite simple:

Below is the protocol in some more detail:

1. The client looks for a compatible idle daemon. If there isn't one, it starts a new daemon.
2. The client connects to the idle daemon and sends it a request to do some work. If the daemon is no longer running, the client starts again.
