设置各个平台数据

using UnityEditor;
public class BuildSettings
{
    public static void UpdateSettings()
    {
        //通用设置
        PlayerSettings.companyName = "TaikrJeff";
        PlayerSettings.productName = "Jump And Run";
        PlayerSettings.bundleVersion = "1.0";

        //安卓平台
        PlayerSettings.applicationIdentifier = "com.Taikr.Jeff.RunAndJump";
    }
}

打包脚本

using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

public class Builder
{
    //打包路径
    private static string buildFolderPath = Application.dataPath + "/../Build";
    //打包
    public static void Build(BuildTarget target, string buildName)
    {
        BuildSettings.UpdateSettings();
        string[] scenes = GetEnabledScenes();
        string buildFullPath = buildFolderPath + "/" + target + "/" + buildName;
        BuildPipeline.BuildPlayer(scenes, buildFullPath, target, BuildOptions.None);
    }
    //获取需要打包的场景
    private static string[] GetEnabledScenes()
    {
        List<string> scenes = new List<string>();
        foreach (EditorBuildSettingsScene scene in EditorBuildSettings.scenes)
        {
            if (scene.enabled)
                scenes.Add(scene.path);
        }

        return scenes.ToArray();
    }
    //创建打包路径文件夹
    public static void CreateBuildFolder()
    {
        if (System.IO.Directory.Exists(buildFolderPath))
        {
            System.IO.Directory.Delete(buildFolderPath, true);
        }

        System.IO.Directory.CreateDirectory(buildFolderPath);
    }
}

打包工具

using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

public class SettingsWindow : EditorWindow
{
    private Dictionary<BuildTarget, string> _targets;
    private const string Prefix = "AppBuilder_";

    public static SettingsWindow instance;
    
    //通过菜单打包android
    [MenuItem("Tools/AppBuilder/BuildAndroid")]
    public static void BuildAndroid()
    {
        Builder.Build(BuildTarget.Android, "RunAndJump.apk");
    }
    //通过菜单打包win
    [MenuItem("Tools/AppBuilder/BuildWindow")]
    public static void BuildWindow()
    {
        Builder.Build(BuildTarget.StandaloneWindows, "RunAndJump.exe");
    }
    //打开打包设置面板
    [MenuItem("Tools/AppBuilder/Show Settings")]
    public static void ShowSettings()
    {
        instance = (SettingsWindow) EditorWindow.GetWindow(typeof(SettingsWindow));
        instance.titleContent = new GUIContent("AppBuilder");
    }

    private void OnEnable()
    {
        InitTargets();
    }

    private void OnGUI()
    {
        DrawPlatformsGUI();
        DrawButtonsGUI();
    }
    //初始化平台
    private void InitTargets()
    {
        _targets = new Dictionary<BuildTarget, string>();
        _targets.Add(BuildTarget.StandaloneWindows, "Windows");
        _targets.Add(BuildTarget.Android, "Android");
    }
    //平台选择Toggle
    private void DrawPlatformsGUI()
    {
        EditorGUILayout.LabelField("Platforms", EditorStyles.boldLabel);
        EditorGUILayout.BeginVertical("box");
        foreach (KeyValuePair<BuildTarget, string> target in _targets)
        {
            DrawPlatformToggle(target.Key, target.Value);
        }

        EditorGUILayout.EndVertical();
    }
    //打包按钮
    private void DrawButtonsGUI()
    {
        if (GUILayout.Button("Build", GUILayout.Height(30)))
            StartBuildProcess();
    }
    //开始打包
    private void StartBuildProcess()
    {
        Builder.CreateBuildFolder();
        foreach (KeyValuePair<BuildTarget, string> target in _targets)
        {
            if (GetPlatformToggleValue(target.Key))
            {
                switch (target.Key)
                {
                    case BuildTarget.Android:
                        Builder.Build(target.Key, "RunAndJump.apk");
                        break;
                    case BuildTarget.StandaloneWindows:
                        Builder.Build(target.Key, "RunAndJump.exe");
                        break;
                }
            }
        }

        EditorUtility.DisplayDialog("AppBuilder", "Build process has finished!", "Ok");
    }
    private void DrawPlatformToggle(BuildTarget target, string label)
    {
        string key = Prefix + target.ToString();
        bool currentValue = EditorPrefs.GetBool(key, false);
        bool newValue = GUILayout.Toggle(currentValue, label);
        EditorPrefs.SetBool(key, newValue);
    }
    private bool GetPlatformToggleValue(BuildTarget target)
    {
        string key = Prefix + target.ToString();
        return EditorPrefs.GetBool(key, false);
    }
}

如图，我们可以通过Tools/AppBuilder下的菜单进行打包。

打包菜单

BuildAndroid打包android
BuildWindow打包Window
ShowSettings打开设置面板

点击ShowSetting按钮，如图：可以一次打包多个平台。

ShowSetting

使用.bat文件在Unity外部打包

注意，需要关闭Unity

这里我把.bat文件放到Assets同级目录下，如图：

bat文件

BuildWindow.bat专为window打包的.bat文件，BuildLog.txt是打包的日志文件。
BuildWindow.bat如下：

"C:\Program Files\Unity\Hub\Editor\2020.2.3f1c1\Editor\Unity.exe" -quit -batchmode -projectPath "C:\Users\17190\Desktop\TestUMP" -executeMethod SettingsWindow.BuildWindow -logFile "BuildLog.txt"
