ignoredFiles property
ignored_files and included_files are file glob matches using https://golang.org/pkg/path/filepath/#Match extended with support for "**".
If ignored_files and changed files are both empty, then they are not used to determine whether or not to trigger a build. If ignored_files is not empty, then we ignore any files that match any of the ignored_file globs. If the change has no files that are outside of the ignored_files globs, then we do not trigger a build.
Implementation
core.List<core.String>? ignoredFiles;
