2.unity 最新版本打包现状

Unity打包与编译，后处理以及自动化等等（持续更新）
然后打包，拉跨，各种失败

unity gradle常见问题解决原理：

无非就是新旧版本的gradle导致的，请参考姊妹篇了解unity中的gradle打包原理。
https://blog.csdn.net/osuckseed/article/details/93089977
举例说明:报错信息很明确
1.明确了必需使用6.1.1 ，unity安装路径下替换即可

2.明确的错误，清单文件合并报错
3.错误位置

unity gradle解决心得：

多测试，快速迭代，注意报错信息：

unity gradle 打包报错信息，多种多样，遇到实在无法解决的如下面这种无任何提示的，删除类库或代码，用二分法查找：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':unityLibrary:processReleaseManifest'.
> java.lang.NullPointerException (no error message)

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 1s
Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8

对于有明确报错的处理方法：

ex1:
error: style attribute 'attr/colorPrimary

ex2:
Execution failed for task ':launcher:processReleaseResources'. 
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade  

ex3:
unity This project uses AndroidX dependencies, but the 'android.useAndroidX'

and so on 有明确错误的一定要百度

对于一些引用了其它类库导致的问题，或是需要使用Gradle7 以上的

先删除打包时的引用，将他们拷贝到libs下，只使用，不参与打包

3.后处理使用案例（IPostGenerateGradleAndroidProject）：

unity后处理修改 gradle.properties

using System.Collections.Generic;
using System.IO;
using UnityEditor.Android;
using UnityEngine;
public class AndroidPostBuildProcessor : IPostGenerateGradleAndroidProject
{
    public int callbackOrder
    {
        get
        {
            return 999;
        }
    }


    void IPostGenerateGradleAndroidProject.OnPostGenerateGradleAndroidProject(string path)
    {
        Debug.Log("Bulid path : " + path);
        string gradlePropertiesFile = path + "/../gradle.properties";
        Debug.Log("Bulid path : " + gradlePropertiesFile);
        if (File.Exists(gradlePropertiesFile))
        {
            File.Delete(gradlePropertiesFile);
        }
        
        using(StreamWriter sw = File.CreateText(gradlePropertiesFile)) 
        { 
			sw.WriteLine("org.gradle.jvmargs=-Xmx4096M");
			sw.WriteLine("org.gradle.parallel=true");
			sw.WriteLine("android.enableR8=false");
			sw.WriteLine("unityStreamingAssets=.unity3d");
            sw.WriteLine("android.useAndroidX=true"); 
            sw.WriteLine("android.enableJetifier=true"); 
        } 
        // StreamWriter writer = File.CreateText(gradlePropertiesFile);
        // // writer.WriteLine("org.gradle.jvmargs=-Xmx4096M");
        // // writer.WriteLine("android.useAndroidX=true");
        // // writer.WriteLine("android.enableJetifier=true");
        //  writer.WriteLine("android.useAndroidX=true"); 
        //  writer.WriteLine("android.enableJetifier=true");
        // writer.Flush();
        // writer.Close();

    }
}

unity 后处理更改清单文件（AndroidManifest）

    public void OnPostGenerateGradleAndroidProject(string path) {
        
        //路径参考
        string k_AndroidManifestPath = "/src/main/AndroidManifest.xml";
        //launcher\build\intermediates\instant_app_manifest\release
        string k_AndroidManifestPath2 = "/launcher/build/intermediates/instant_app_manifest/release/AndroidManifest.xml";
        
        var manifestPath = path + "/.."+k_AndroidManifestPath2;
        if (!File.Exists(manifestPath))
        {
            
        }
        else
        {
            //string[] str = File.ReadAllLines(path);
            string str = File.ReadAllText(manifestPath);
            Debug.Log("id:"+manifestPath);
            Debug.Log("id:"+Application.identifier);
            Debug.Log("id:"+path);
            var bef = str.Contains(Application.identifier);
            Debug.Log("ber:"+bef.ToString());
            str = Regex.Replace(str,Application.identifier,"ltbase_package_name");  
            var afte = str.Contains(Application.identifier);
            Debug.Log("afte:"+afte.ToString());
            File.WriteAllText(manifestPath,str);
        }
        
    }

Unity xode工程后处理

        //为plist写入项目中需要的配置 一般项目中接入微信会需要
        string plistPath = System.IO.Path.Combine(pathToBuiltProject, "Info.plist");
        PlistDocument plist = new PlistDocument();
        plist.ReadFromFile(plistPath);
        PlistElementDict dict = plist.root.CreateDict("NSAppTransportSecurity");
        dict.SetBoolean("NSAllowsArbitraryLoads", true);

后处理函数的具体使用（PostProcessBuildAttribute）

打包完成后的一些文件的拷贝删除与替换文章来源地址https://www.toymoban.com/news/detail-421018.html

// C# example:
using UnityEngine;
using UnityEditor;
using UnityEditor.Callbacks;

public class MyBuildPostprocessor {
    [PostProcessBuildAttribute(1)]
    public static void OnPostprocessBuild(BuildTarget target, string pathToBuiltProject) {
        Debug.Log( pathToBuiltProject );
        }
}
