 * An exception thrown by various error conditions that are severe enough to halt the command (e.g.
 * even a --keep_going build). These typically need to signal to the handling code what happened.
 * Therefore, these exceptions contain a {@link DetailedExitCode} specifying a numeric exit code and
 * a detailed failure for the command to return.
 *
 * <p>When an instance of this exception is thrown, Bazel will try to halt the command as soon as
 * reasonably possible.
