本文解决离线安装SDK时dx.jar文件不一致导致的错误，确保平台工具库和开发版本库中dx.jar文件的一致性即可修正问题。
出现这样的错误，可能是没安装好sdk，可以修正一下，尤其是离线安装，有可能导致。确保dx.jar这个文件在platform-tools\lib和选择的开发版本lib中的文件一致就可以

修改之后会出现了一个提示，单击并选择sync [to version 30]。Android Studio会自动下载BuildTool V30并更改项目设置。不将SDK构建工具31降级到30，也不更改编译SDK版本，主要是SDK构建工具31上缺少2个文件，即。，解决方案是这些文件在文件位置中被命名为。的文件，这是Windows批处理文件。是一个隐藏文件夹，打开隐藏项就可以看到。，因此将它们的名称更改为。

首先，我在 Android Studio 4.2.2 中遇到了这个问题，您不需要将 SDK 构建工具从 31 降级到 30 或更改编译 SDK 版本。 主要问题是 SDK 构建工具 31 中缺少的两个文件是： dx.bat dx.jar 解决方案是这些文件在文件位置命名为 d8，因此将它们的名称更改为 dx 将解决错误。 步骤如下。 对于 Windows 去那个位置 "C:\Users\user\AppData\Local\Android\Sdk\build-tools\31.0.0" 找到一个.

<think>好的，我现在需要解决用户遇到的Unity导出Android项目时出现的错误：“CommandInvokationFailure: Unable to convert classes into dex format”。用户提供了详细的错误日志，显示多个类文件存在InnerClasses属性问题，以及重复添加类的错误，最终导致构建失败。 首先，我需要理解错误的根本原因。根据日志，有几个关键点： 1. **InnerClasses属性警告**：多个类如com.tencent.mm.sdk.b.b和com.testin.agent.a.b缺少EnclosingMethod属性，这通常是因为这些类是用旧版本的编译器生成的，不支持现代.class文件格式。虽然这些是警告，但可能影响后续处理。 2. **重复类错误**：日志中出现多个“already added”错误，例如Lbitter/jnibridge/JNIBridge;和Lcom/unity3d/player/NativeLoader;等类被重复添加。这可能是由于依赖冲突，多个库引入了相同的类。 3. **Unity版本过旧**：用户使用的是Unity 5.3.8，这是一个非常旧的版本（2016年发布），可能不支持较新的Android SDK或Java版本，导致兼容性问题。 接下来，我需要考虑可能的解决方案。根据之前的对话历史，用户已经询问过关于FileProvider配置和Multidex的问题，现在的问题是构建失败，涉及类转换为dex格式的问题。 可能的解决步骤： 1. **更新Unity版本**：建议用户升级到更高版本的Unity，比如2019.4或以上，以获得更好的兼容性和支持。 2. **检查JDK版本**：用户使用的是JDK 1.8，虽然Unity 5.3.8支持JDK 1.8，但可能存在兼容性问题。但考虑到Unity版本老旧，升级Unity可能更有效。 3. **解决重复类冲突**：检查项目中的插件，特别是微信SDK和Testin插件，可能存在与其他库的冲突。需要更新这些插件到最新版本，或者手动移除重复的依赖库。 4. **启用Multidex**：如果方法数超过限制，需要启用Multidex，但用户可能已经尝试过，但需要确认配置是否正确。 5. **清理项目并重新导入插件**：删除旧的插件和缓存，重新导入必要的插件，确保没有重复的类文件。 6. **ProGuard混淆**：使用ProGuard来移除无用的类和方法，减少冲突的可能性。 现在需要将这些思考整理成一个结构化的回答，分步骤说明，并提供相关问题。需要注意用户可能对Unity版本升级有顾虑，比如项目迁移的复杂性，但必须强调必要性。同时，重复类的问题可能需要详细检查插件依赖，用户可能需要指导如何查找和解决依赖冲突。 另外，用户日志中还有“message truncated”，可能表示日志被截断，需要提醒用户检查完整日志是否有更多信息。但根据现有信息，可以推断出上述可能的原因和解决方法。</think>以下是修复 **`Unable to convert classes into dex format`** 的完整指南： --- ### 🔍 **错误原因分析** #### 1. **类重复冲突** - **关键错误**： `already added: Lcom/unity3d/player/NativeLoader;` `already added: Lbitter/jnibridge/JNIBridge;` - **原因**：多个插件或依赖库包含相同类（如 `UnityPlayer`、`JNIBridge`、`ReflectionHelper`）。 - **冲突来源**： - 微信 SDK、Testin 插件与 Unity 内置类重复。 - 第三方插件使用了旧版 `android.support.v4` 或 `androidx` 库。 #### 2. **Java 类版本不兼容** - **警告**： `Ignoring InnerClasses attribute for an anonymous inner class` - **原因**：`com.tencent.mm.sdk.b.b` 和 `com.testin.agent.*` 由旧版编译器生成，缺少 `EnclosingMethod` 属性。 #### 3. **Unity 版本过时** - **问题**：Unity 5.3.8（2016 年发布）内置的 `sdktools.jar` 无法处理现代 Java 类文件。 --- ### ✅ **修复步骤** #### 1. **清理重复类冲突** - **操作**： 1. **删除重复插件**： - 检查 `Plugins/Android` 目录，移除重复的 JAR/AAR 文件（如 `classes.jar`、`FanweiPlugin_v4.4.jar`）。 2. **使用 `exclude` 排除冲突依赖**： - 在 `build.gradle` 中添加排除规则（适用于自定义构建）： ```gradle dependencies { implementation('com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+') { exclude group: 'com.unity3d.player', module: 'UnityPlayer' } } ``` #### 2. **更新插件版本** - **操作**： 1. **升级微信 SDK**： - 从 [微信开放平台](https://open.weixin.qq.com/) 下载最新版 SDK（如 `6.8.0`）。 2. **更新 Testin 插件**： - 从 [Testin 官网](https://www.testin.cn/) 获取兼容 Android 10+ 的最新版本。 #### 3. **升级 Unity 引擎** - **操作**： 1. **备份项目**： - 备份 `Assets/` 和 `ProjectSettings/`。 2. **使用 Unity Hub 升级**： - 安装 Unity 2019.4 LTS 或 2021.3 LTS。 3. **迁移项目**： - 打开 Unity Hub → `Add Existing Project` → 选择项目目录。 #### 4. **启用 ProGuard 混淆** - **操作**： 1. **开启混淆**： - Unity Editor → `Edit > Project Settings > Player Settings` → `Android > Write Ahead Native Debugging = true`。 2. **添加排除规则**： - 在 `Assets/Plugins/Android/proguard-user.txt` 中添加： ```proguard -keep class com.tencent.mm.sdk.** { *; } -keep class com.testin.agent.** { *; } -keep class bitter.jnibridge.** { *; } ``` #### 5. **手动修复类文件（高级）** - **操作**： 1. **使用 Recaf 反编译插件 JAR**： ```bash java -jar Recaf.jar -input FanweiPlugin_v4.4.jar ``` 2. **修复 `InnerClasses` 属性**： - 手动添加 `EnclosingMethod` 属性（需熟悉 Java 字节码）。 3. **重新编译并签名**： - 使用 `javac` 重新编译修改后的类文件。 --- ### 🧪 **完整修复示例** #### 修复前（错误配置）： ```bash # Unity 5.3.8 + 微信 SDK 1.8.0 + Testin 插件 4.0.0 Error: Unable to convert classes into dex format. ``` #### 修复后（推荐配置）： ```bash # Unity 2021.3 + 微信 SDK 6.8.0 + Testin 插件 5.0.0 Build Success! ``` --- ### 🛠️ **工具辅助检查** 1. **查看完整构建日志**： - 删除 `Temp/` 和 `Library/` 后重新构建，检查 `Editor.log`。 2. **使用 `dexdump` 分析 Dex 文件**： ```bash dexdump -l xml classes.dex > classes.xml ``` 3. **依赖冲突检测**： - 使用 [JarAnalyzer](https://github.com/tnachen/jaranalyzer) 检查重复类： ```bash java -jar jaranalyzer.jar analyze Plugins/Android/ ``` --- ### 📌 **注意事项** - **Android SDK 版本兼容性**： - Unity 2021.3 需使用 Android SDK API 30（Android 11）。 - 确保 `SDK Tools` 已更新： ```bash SDK Manager → Android SDK → 更新至 30.x.x ``` - **JDK 版本匹配**： - Unity 2021.3 需使用 JDK 11（通过 Unity Hub 自动安装）。 --- ### ✅ **最终验证** 1. **清理 Unity 缓存**： - 删除 `Temp/`、`Library/` 和 `UserSettings/`。 2. **重新构建项目**： - Unity → `File > Build Settings > Build`。 3. **安装测试**： - 在 Android 设备上运行应用，确认无 `NoClassDefFoundError`。 ---
