Remarks

Before you can use 
BuildScriptsOnly
, you need to build the whole Project. Then you can run builds that only have script changes. Rebuilding the player data will be skipped for faster iteration speed.
Platforms which support the incremental build pipeline will automatically run scripts only builds if Unity detects that the data files have not changed, even if 
BuildScriptsOnly
is not used. You can still use 
BuildScriptsOnly
to force a script only build and ignore any pending player data changes.
The following script example uses 
BuildScriptsOnly
. The script builds the entire Project initially. After you've run the script for the first time, you can use the script to only compile any changes you make to the script. To try this out, add the following Editor script and the game script to your project.
using UnityEditor;using UnityEngine;public class EditorExample : MonoBehaviour{    [MenuItem("Build/Build scripts")]    public static void MyBuild()    {        BuildPlayerOptions buildPlayerOptions = new BuildPlayerOptions();        buildPlayerOptions.scenes = new[] { "Assets/scene.unity" };        buildPlayerOptions.locationPathName = "scriptBuilds";        buildPlayerOptions.target = BuildTarget.StandaloneOSX;        // use these options for the first build        buildPlayerOptions.options = BuildOptions.Development;        // use these options for building scripts        // buildPlayerOptions.options = BuildOptions.BuildScriptsOnly | BuildOptions.Development;        BuildPipeline.BuildPlayer(buildPlayerOptions);    }}
Attach the following simple script to an empty GameObject in the scene:
using UnityEngine;// Change the camera to the usual blue color and display a label.public class ExampleClass : MonoBehaviour{    private Camera cam;    void Awake()    {        cam = Camera.main;        cam.clearFlags = CameraClearFlags.SolidColor;    }    void OnGUI()    {        GUI.Label(new Rect(100, 100, 100, 50), "ExampleClass");    }}
Now run the 
Build/Build scripts
example. This builds an executable. Run that executable and a dark blue window with the label appears. Next add some cubes and spheres to the Project. Make the following script changes:
using UnityEngine;public class ExampleClass : MonoBehaviour{    private Camera cam;    // added line    private float delay;    void Awake()    {        delay = 0.0f;        cam = Camera.main;        cam.clearFlags = CameraClearFlags.SolidColor;    }    // added script code    void FixedUpdate()    {        delay = delay + Time.deltaTime;        if (delay > 0.5f)        {            cam.backgroundColor = new Color(0.0f, 0.0f, Random.Range(0.0f, 0.25f));            delay = 0.0f;        }    }    void OnGUI()    {        GUI.Label(new Rect(100, 100, 100, 50), "ExampleClass");    }}
Finally, swap the commented lines in the 
EditorExample
script:
using UnityEditor;using UnityEngine;public class EditorExample : MonoBehaviour{    [MenuItem("Build/Build scripts")]    public static void MyBuild()    {        BuildPlayerOptions buildPlayerOptions = new BuildPlayerOptions();        buildPlayerOptions.scenes = new[] { "Assets/scene.unity" };        buildPlayerOptions.locationPathName = "scriptBuilds";        buildPlayerOptions.target = BuildTarget.StandaloneOSX;        // use these options for the first build        // buildPlayerOptions.options = BuildOptions.Development;        // use these options for building scripts        buildPlayerOptions.options = BuildOptions.BuildScriptsOnly | BuildOptions.Development;        BuildPipeline.BuildPlayer(buildPlayerOptions);    }}
Use the 
Build/Build scripts
to regenerate the application and then launch it. The application will now show random changes to the background color. However the added cubes and spheres are not visible.
