    MapDifference<Integer, String> original = Maps.difference(left, right);
    MapDifference<Integer, String> same = Maps.difference(left, right);

Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

## Design

Then I spent some time designing the developer "API" I wanted to have as a user (as a developer using FastAPI).

	flags := &diffFlags{
		kubeConfigPath: constants.GetAdminKubeConfigPath(),
		out:            out,
	}

	cmd := &cobra.Command{
		Use:   "diff [version]",
		Short: "Show what differences would be applied to existing static pod manifests. See also: kubeadm upgrade apply --dry-run",
		RunE: func(cmd *cobra.Command, args []string) error {
			// Run preflight checks for diff to check that the manifests already exist.

            }
            // Ignore contents of maven-metadata.xml.sha256, etc, because hashes will most likely
            // change between runs due to <lastUpdated /> differences.
            return ''
        }
        return repositoryFile.text
    }

    private String clearLastUpdatedElementOf(String metadata) {
        metadata.replaceAll(

// return [SkipDir] or [SkipAll] and avoid the ReadDir entirely. The second call
// is after a failed ReadDir and reports the error from ReadDir.
// (If ReadDir succeeds, there is no second call.)
//
// The differences between WalkDirFunc compared to [path/filepath.WalkFunc] are:
//
//   - The second argument has type [DirEntry] instead of [FileInfo].
//   - The function is called before reading a directory, to allow [SkipDir]

# The suggested '-compat' flag to ignore differences should silence the error
# and leave go.mod unchanged, resulting in checksum errors when Go 1.16 tries
# to load a module pruned out by Go 1.17.

go mod tidy -compat=1.17
! stderr .
cmp go.mod go.mod.orig

                    }
                }
            }
        }
    }

    private static String normalizeUri(URI uri) throws URISyntaxException {
        // We have to go through URIish and back to deal with differences between how
        // Java File and Git implement file URIs.
        return new URIish(uri.toString()).toPrivateASCIIString();
    }

    private static GitVersionControlSpec cast(VersionControlSpec spec) {

			return fmt.Errorf("Expected command line argument %s, seen %s", cmdLine,
				s2.CmdLines[i])
		}
	}

	if reflect.DeepEqual(s1.MinioEnv, s2.MinioEnv) {
		return nil
	}

	// Report differences in environment variables.
	var missing []string
	var mismatching []string
	for k, v := range s1.MinioEnv {
		ev, ok := s2.MinioEnv[k]
		if !ok {
			missing = append(missing, k)
		} else if v != ev {

For example, the following setup would break caching of `Test` tasks, since Gradle always detects the differences in custom task actions.
