无法设置新的虚幻和任务2开发环境



我甚至无法获得一个以Quest 2平台为目标的空虚幻项目来构建没有错误的Android目标。这似乎与各种相互不兼容的Java/SDK/NDK/Gradle版本的混乱有关，我找不到一个有效的组合。这是我目前根据Unreal:中的Android Studio和Android SDK平台设置使用的内容

android sdk：

  • 已安装API 28级
  • 已安装API 30级
  • 已安装API 31级
  • SDK生成工具31已安装，但随后被删除，因为生成报告了损坏的版本
  • SDK构建工具30.0.3已安装
  • SDK构建工具29.0.2已安装
  • 为SDK API级别latest配置了虚幻环境
  • Unreal项目配置为目标SDK版本28(最低23(
  • 我已经在D:/android-sdk明确提供了Unreal Platform Android SDK设置的位置，该位置与Android Studio中指定的位置匹配，但Android Studio使用，Unreal使用/

android ndk：

  • 我安装了22.1.7171670
  • 我已在D:/android-sdk/ndk/22.1.7171670向Unreal明确提供了位置
  • 我已告知虚幻使用NDK APIlatest级

java：

  • 我在D:\Java上安装了JDK 16.0.1
  • 我已经明确告诉Unreal Android SDK设置使用D:/Java中的JAVA

梯度：

  • 我更新了UE_4.26\Engine\Build\Android\Java\gradle\gradle\uwrapper\gradle-wrapper.properties文件以引用distributionUrl=https://services.gradle.org/distributions/gradle-7.0-bin.zip，并由于其他一些我现在不记得的错误而注释掉了#distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip

当我尝试在这个环境中构建一个项目时(使用文件>包项目>安卓>Android(Multi:ASTC、DXT、ETC2(，我的输出的结尾看起来是这样的：

我将SDK目标从28更改为30，并将JAVA目录从D:/Java更改为C:/Program Files/Java/jdk1.8.0_161，然后错误更改为：

如果我将这两个设置中的一个或两个更改回以前的值，则错误不会更改回第一个错误。如果我(再次(将目标SDK版本更改回30，那么我会再次得到原始错误，这次目标SDK版本设置为30。因此，JDK版本似乎是罪魁祸首，但需要更改Target SDK版本才能强制重建某些内容，尽管我有"完全重建"；在"项目打包设置"中选择。

问题

所以我的问题是，我该如何克服这两个错误？

  1. 无法使字段私有的最终java.lang.String java.io.File.path可访问：模块java.base不"打开java.io"；至未命名模块@5caa5e6c
  2. 查询映射的映射值(java.io.File属性(org.gradle.api.File.Directory，fixed(类org.gradle/ai.internal.File.DefaultFilePropertyFactory$FixedDirectory，Z:\downloader_brary\build\generated\ap_generated_sources\debug\out((org.gradle_api.internal.File.DefaultFileProperty工厂$ToFileTransformer@2ccc294e)不支持在任务"：downloader_brary:compileDebugJavaWithJavac"完成之前

需要将Gradle降级回distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip这只起过一次作用。我无法使用相同的设置重新生成。似乎存在一些时间问题，可能需要等待https://github.com/gradle/gradle/issues/16777以便克服错误。每次构建时，我都会看到不同的错误。我至少看到了6个不同的错误。在删除中间目录和已保存目录后，我在第二次尝试中成功构建了这些目录。

似乎需要jdk1.8.0_321而不是JDK16/17。这让我能够始终如一地为Quest构建(我没有Quest 2，但它也应该在那里工作(

除此之外，你在这里提供的所有设置都解决了我的问题。
