By inspecting a greater range of build operations for failure, the Job
summary will correctly reflect the build outcome in more circumstances.
Note that we now use the old 'buildFinished' mechanism for all Gradle
versions < `7.0`, instead of using the BuildService mechanism for all
Gradle versions from `6.6`. This avoids needing to deal with
inconsistent build operations present in Gradle versions `[6.6, 7.0)`.
Fixes#415
The Gradle build used to perform cache-cleanup will run in the context of init-scripts
provided by the action, including those that collect build-results.
In some circumstances this can lead to unexpected results, such as saving configuration-cache
entries for cache cleanup executions.
With this change, build results will not be captured for cache-cleanup builds.
