== Publish a Build Scan

The best way to learn more about what your build is doing behind the scenes, is to publish a link:https://scans.gradle.com[build scan].
To do so, just run Gradle with the `--scan` flag.

[listing.terminal.sample-command]
----
\$ ./gradlew build --scan

BUILD SUCCESSFUL in 0s
${tasksExecuted.raw} actionable tasks: ${tasksExecuted.raw} executed

For example, with a build scan, it’s no longer necessary to copy and paste error messages or include all the details about your environment each time you want to ask a question on Stack Overflow, Slack, or the Gradle Forum.
Instead, copy the link to your latest build scan.

== Enable Build Scans

To enable build scans on a gradle command, add `--scan` to the command line option:

[source,text]

	dst.Write(b)
	return err
}

func appendIndent(dst, src []byte, prefix, indent string) ([]byte, error) {
	origLen := len(dst)
	scan := newScanner()
	defer freeScanner(scan)
	needIndent := false
	depth := 0
	for _, c := range src {
		scan.bytes++
		v := scan.step(scan, c)
		if v == scanSkipSpace {
			continue
		}
		if v == scanError {
			break
		}

	return string(result), err
}

// UnixSecondSerializer json serializer
type UnixSecondSerializer struct{}

// Scan implements serializer interface
func (UnixSecondSerializer) Scan(ctx context.Context, field *Field, dst reflect.Value, dbValue interface{}) (err error) {
	t := sql.NullTime{}
	if err = t.Scan(dbValue); err == nil && t.Valid {
		err = field.Set(ctx, dst, t.Time.Unix())
	}

	return
}

    enum BuildScanRequest {
        NONE, // no explicit request
        REQUESTED, // --scan is present, but not --no-scan
        SUPPRESSED // --no-scan is present
    }

    BuildScanRequest getBuildScanRequest();

    boolean isTaskExecutingBuild();

    /**
     * Whether the plugin was auto-applied via {@code --scan} without being explicitly applied.

In the above build scan, configuration takes over 13 seconds.
Click on the _"Configuration"_ tab to break this stage into component parts,
exposing the cause of the slowness.
