## 前言 ##

有个紧急问题需要修复，本以为很快就能解决继续休假，没想到项目打开运行后Android端跑不起来了，iOS端正常运行，这就有点莫名其妙，明明放假前还是没问题的，难道我拉取的最新代码有问题？不会吧，谁放假还敲代码啊？?️看了下最新的提交记录，还是放假前我提交的，那就肯定不是项目的问题。

## 开发环境 ##

*  Android Studio: 2022.1.1
 *  Flutter: 3.3.10

## 问题描述 ##

Android端构建运行失败，报错信息如下：

Execution failed for task ':app:processDebugMainManifest'.
    > Unable to make field private final java.lang.String java.io.File.path accessible: module java.base does not "opens java.io" to unnamed module

**2023/08/14更新：当前问题已被修复，如果你还遇到以上报错，可以参考这篇文章[Android问题记录 - Unable to make field private final java.lang.String java.io.File.path accessible（持续更新）][Android_ - Unable to make field private final java.lang.String java.io.File.path accessible]。当然，如果你是Flutter开发者，当前文章也值得一读。**

## 问题分析 ##

先网上搜一搜，大部分都是说JDK版本有问题，提到JDK版本我想到放假最后一天升级了Android Studio版本，从`2021.3.1`升级到`2022.1.1`，这应该算大版本更新，难道是这个升级导致JDK版本出问题了。尝试设置项目的JDK版本，折腾一番无果。

既然是Flutter项目，那可以尝试用Flutter命令检查Android Studio正不正常：

flutter doctor

执行输出：

[✓] Flutter (Channel stable, 3.3.10, on macOS 13.0.1 22A400 darwin-x64, locale
        zh-Hans-CN)
    [!] Android toolchain - develop for Android devices (Android SDK version 33.0.1)
        ✗ Android license status unknown.
          Run `flutter doctor --android-licenses` to accept the SDK licenses.
          See https://flutter.dev/docs/get-started/install/macos#android-setup for
          more details.

    [✓] VS Code (version 1.74.2)
    [✓] Connected device (3 available)
    [✓] HTTP Host Availability

原来真有问题，还不止一个，那就逐个解决。

1.  Android license status unknown

这个问题的解决办法Flutter已经给出了，执行下方命令即可：

flutter doctor --android-licenses

执行输出：

Error: A JNI error has occurred, please check your installation and try again
    Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/prefs/AndroidLocationsProvider has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

    	at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:632)

好家伙，这命令执行竟然报错了，我记得老早以前执行过没报错，网上一搜又是JDK版本问题。奇了怪了，虽然我电脑上有装多个版本的JDK，但是Android Studio一直是用的自带的JRE。

**2023/08/14更新：当前问题已被修复，如果你还遇到以上报错，那么可能是JDK版本太低导致的，可以参考本篇文章评论中的方法，尝试升级JDK版本解决。**

1.  Unable to find bundled Java version

这个报错是说找不到捆绑的Java版本?️，难道新版的Android Studio移除了自带的JRE？这么一想好像已经找到问题的根源所在了。接下来就是验证这个想法。

首先把[Flutter][]框架项目代码拉下来，搜索关键词`Unable to find bundled Java version`：

![screenshot1][]

关键代码（位于Flutter框架项目下的`packages/flutter_tools/lib/src/android/android_studio.dart`文件）：

final String javaPath = globals.platform.isMacOS ?
        version != null && version.major < 2020 ?
        globals.fs.path.join(directory, 'jre', 'jdk', 'Contents', 'Home') :
        globals.fs.path.join(directory, 'jre', 'Contents', 'Home') :
        globals.fs.path.join(directory, 'jre');
    final String javaExecutable = globals.fs.path.join(javaPath, 'bin', 'java');
    if (!globals.processManager.canRun(javaExecutable)) {
        
      _validationMessages.add('Unable to find bundled Java version.');
    } else {
        
    // 省略
    }

这段代码的作用就是拼接Java可执行程序的路径，并验证是否能执行。现在我们把涉及到路径的几个变量打印出来，打印很简单，这是Dart写的，直接用`print`方法就可以了。

print('directory: $directory');
    print('javaPath: $javaPath');
    print('javaExecutable: $javaExecutable');

现在的问题是怎么执行到修改后的文件，当我们执行`flutter doctor`命令时，会执行到`packages/flutter_tools/bin/flutter_tools.dart`文件（后面会分析），然后再进一步解析命令执行。所以我们直接通过Dart命令执行`flutter_tools.dart`文件是不是就可以了。

dart flutter_tools.dart doctor

切换到Flutter框架项目的`packages/flutter_tools/bin`目录下执行输出：

    // Copyright 2014 The Flutter Authors. All rights reserved.

    ^

执行报错了，原因是Dart SDK版本低了，电脑上当前的Dart SDK版本是2.18，拉下来的Flutter框架项目代码要求更高的版本。这时候不用去下载最新的Dart SDK版本，Flutter框架项目是自带Dart SDK的，位于项目`bin/cache/dart-sdk`路径下。

**2023/01/26更新：以上说明有点问题，实际的Flutter框架项目默认是不带Dart SDK的，如果你没找到，请看补充说明1。**

指定Dart可执行程序路径：

flutter框架项目路径/bin/cache/dart-sdk/bin/dart flutter_tools.dart doctor

或者用这个，这个最终也是用到了`bin/cache/dart-sdk/bin/dart`：

flutter框架项目路径/bin/dart flutter_tools.dart doctor

执行输出（省略部分）：

directory: /Applications/Android Studio.app/Contents
    javaPath: /Applications/Android Studio.app/Contents/jre/Contents/Home
    javaExecutable: /Applications/Android Studio.app/Contents/jre/Contents/Home/bin/java

接下来检查`/Applications/Android Studio.app/Contents`路径下文件，可以选择\[访达\] -> \[顶部菜单栏的前往\] -> \[前往文件夹\] -> \[输入路径跳转\]或\[应用程序\] -> \[Android Studio.app\] -> \[右键显示包内容\] -> \[Contents\]。

![screenshot2][]

实锤了，新版本的Android Studio真的移除了JRE，`jre`目录找不到，怪不得报错了，不过多了一个`jbr`目录，找了个以前的Android Studio版本对比（[旧版下载][Link 1]，不是很全）：

![screenshot3][]

搜了一下`jbr`（JetBrains Runtime），原来IDEA老早就开始用了，是基于OpenJDK修改的东西。不知道为什么Android Studio从`2022.1.1`版本才开始支持，去下载了两个[预览版][Link 2]也是没有`jre`目录了，说明后续应该都没了。

综上，问题的根源在于Android Studo移除了`jre`目录。那如果我直接修改代码，将路径拼接过程中的`jre`改为`jbr`是不是就没问题了，实测可行，执行`flutter框架项目路径/bin/cache/dart-sdk/bin/dart flutter_tools.dart doctor`命令一切正常。

## 解决方案 ##

如果你略过了前面的问题分析，请注意，以下所说的`jbr`所在目录路径为：

*  macOS系统：`/Applications/Android Studio.app/Contents`
 *  Windows系统：Android Studio的安装目录

**2023/01/30更新：实测以下三种解决方法在Flutter 3.7.0版本依旧适用。对于前两种方法，如果你尝试后未能解决，请先检查上方所说的目录中是否有`jre`目录或者软链接。**

这里提供三种解决方法（任选一种）：

1.  简单粗暴的方法

*  如果是macOS系统，在`jbr`同目录下创建一个`jre`目录，然后将`jbr`目录内的全部文件复制一份到`jre`目录下即可。
 *  如果是Windows系统，`jre`目录是存在的，不过里面几乎没东西，可以直接将`jbr`目录内的全部文件复制一份到`jre`目录下即可。

1.  创建软链接的方法

*  如果是macOS系统，切换到`jbr`所在目录执行命令：

ln -s jbr jre

注意，如果是通过cd命令切换到`jbr`所在目录，需要对路径中的空格进行转义或用单/双引号包裹路径，例如`cd /Applications/Android\ Studio.app/Contents`。

*  如果是Windows系统，使用管理员身份打开终端（可以按`Win+X键`，然后选择`Windows 终端（管理员）`），切换到`jbr`所在目录执行命令：

mklink /D jre jbr

这里有几点要注意：

*  一定要管理员身份运行，不然权限不足会报错提示`你没有足够的权限执行此操作`
 *  如果打开终端默认用的是`PowerShell`（输入命令那一行最前面有`PS`字符），需要输入`cmd`切换到命令提示符，这是因为`PowerShell`不支持`mklink`命令
 *  执行命令前需要删除已经存在的`jre`目录，不然会报错提示`当文件已存在时，无法创建该文件`
 *  右键创建快捷方式实测是行不通的，这种方式创建的快捷方式其实是创建了一个新的文件，只不过这个文件属性里面包含了目标路径，查看这个文件大小，才1000字节。通过`mklink`命令方式创建的，文件大小和占用空间等属性和目标文件属性一致。

**2023/02/05更新：通过以上两种方法解决后，Android Studio后续升级可能会遇到如下所示问题：**

![screenshot4][]

**如果你当前的Flutter版本已经修复了该问题，点击`Proceed`删除添加的`jre`目录或者软链接即可。如果还未修复又想继续升级（点击`Proceed`），请按之前的方法将被删除的`jre`目录或者软链接添加回去。**

1.  修改Flutter框架代码的方法（不推荐，有点麻烦，感兴趣的可以看看）

前面问题分析中尝试修改代码是可行的，但是那是在Flutter框架项目下改的，现在我们要做的是对当前电脑上的Flutter SDK进行修改。首先找到Flutter SDK目录：

![screenshot5][]

如果你见过Flutter框架项目的目录结构，你会发现一模一样，那是不是说，直接修改目录下的`packages/flutter_tools/lib/src/android/android_studio.dart`文件就好了，将`jre`改为`jbr`，实测没变化。这难道还需要编译？是的，确实还要做一些处理。

从`flutter doctor`命令的执行开始分析，首先找到`flutter`可执行文件（位于Flutter SDK的`bin`目录下），这个本质是一个shell脚本，可以用文本工具打开，有点长就贴一个脚本的关键部分：

source "$BIN_DIR/internal/shared.sh"
    
    shared::execute "$@"

在脚本的最后执行了`shared::execute`（`::`是命名约定，用于分隔库）函数，并将命令执行时的参数传递下去。找到`shared.sh`文件（位于Flutter SDK的`bin/internal`目录下）中的`shared::execute`函数：

# This function is intended to be executed by entrypoints (e.g. `//bin/flutter`
    # and `//bin/dart`). PROG_NAME and BIN_DIR should already be set by those
    # entrypoints.
    function shared::execute() {
        
      export FLUTTER_ROOT="$(cd "${BIN_DIR}/.." ; pwd -P)"
    
      # If present, run the bootstrap script first
      BOOTSTRAP_PATH="$FLUTTER_ROOT/bin/internal/bootstrap.sh"
      if [ -f "$BOOTSTRAP_PATH" ]; then
        source "$BOOTSTRAP_PATH"
      fi
    
      FLUTTER_TOOLS_DIR="$FLUTTER_ROOT/packages/flutter_tools"
      SNAPSHOT_PATH="$FLUTTER_ROOT/bin/cache/flutter_tools.snapshot"
      STAMP_PATH="$FLUTTER_ROOT/bin/cache/flutter_tools.stamp"
      SCRIPT_PATH="$FLUTTER_TOOLS_DIR/bin/flutter_tools.dart"
      DART_SDK_PATH="$FLUTTER_ROOT/bin/cache/dart-sdk"
    
      DART="$DART_SDK_PATH/bin/dart"
    
      # If running over git-bash, overrides the default UNIX executables with win32
      # executables
      case "$(uname -s)" in
        MINGW*)
          DART="$DART.exe"
          ;;
      esac
    
      # Test if running as superuser – but don't warn if running within Docker or CI.
      if [[ "$EUID" == "0" && ! -f /.dockerenv && "$CI" != "true" && "$BOT" != "true" && "$CONTINUOUS_INTEGRATION" != "true" ]]; then
        >&2 echo "   Woah! You appear to be trying to run flutter as root."
        >&2 echo "   We strongly recommend running the flutter tool without superuser privileges."
        >&2 echo "  /"
        >&2 echo "?"
      fi
    
      # Test if Git is available on the Host
      if ! hash git 2>/dev/null; then
        >&2 echo "Error: Unable to find git in your PATH."
        exit 1
      fi
      # Test if the flutter directory is a git clone (otherwise git rev-parse HEAD
      # would fail)
      if [[ ! -e "$FLUTTER_ROOT/.git" ]]; then
        >&2 echo "Error: The Flutter directory is not a clone of the GitHub project."
        >&2 echo "       The flutter tool requires Git in order to operate properly;"
        >&2 echo "       to install Flutter, see the instructions at:"
        >&2 echo "       https://flutter.dev/get-started"
        exit 1
      fi
    
      upgrade_flutter 7< "$PROG_NAME"
    
      BIN_NAME="$(basename "$PROG_NAME")"
      case "$BIN_NAME" in
        flutter*)
          # FLUTTER_TOOL_ARGS aren't quoted below, because it is meant to be
          # considered as separate space-separated args.
          exec "$DART" --disable-dart-dev --packages="$FLUTTER_TOOLS_DIR/.dart_tool/package_config.json" $FLUTTER_TOOL_ARGS "$SNAPSHOT_PATH" "$@"
          ;;
        dart*)
          exec "$DART" "$@"
          ;;
        *)
          >&2 echo "Error! Executable name $BIN_NAME not recognized!"
          exit 1
          ;;
      esac
    }

函数有点长，直接看最后面就好。最后有个分支语句，根据`BIN_NAME`的值走不同分支，把相关的变量打印出来看看：

echo "PROG_NAME: $PROG_NAME"
    echo "BIN_NAME: $BIN_NAME"

执行`flutter doctor`输出（省略部分）：

PROG_NAME: /usr/local/Caskroom/flutter/3.3.10/flutter/bin/flutter
    BIN_NAME: flutter

根据输出结果可以判断，走的是第一个分支，执行`exec "$DART" --disable-dart-dev --packages="$FLUTTER_TOOLS_DIR/.dart_tool/package_config.json" $FLUTTER_TOOL_ARGS "$SNAPSHOT_PATH" "$@"`。之所以会有这个分支判断，是因为Dart命令最终也会执行到这个函数，执行Dart相关命令输出（省略部分）:

PROG_NAME: /usr/local/Caskroom/flutter/3.3.10/flutter/bin/dart
    BIN_NAME: dart

分析到这，好像也没用到`SCRIPT_PATH`变量（`flutter_tools.dart`的路径，请看上述脚本函数代码中的定义），前面问题分析中提到执行`flutter doctor`命令时，会执行到`packages/flutter_tools/bin/flutter_tools.dart`文件，这难道是假的？不能说是假的，只能说有点偏差。如果是在这直接执行`packages/flutter_tools/bin/flutter_tools.dart`文件的，那前面一开始修改代码就可以生效了，原因在于这边是用Dart命令执行`SNAPSHOT_PATH`所指向的快照文件（`flutter_tools.snapshot`）去了。

`flutter_tools.snapshot`是通过Dart命令生成的快照文件，那我们是不是也可以生成一个快照文件替换掉自带的？切换到Flutter SDK目录的`packages/flutter_tools/bin`路径下执行命令：

dart --snapshot=flutter_tools.snapshot flutter_tools.dart

**2023/01/26更新：如果生成快照文件报错，请看补充说明2。**

然后将生成的`flutter_tools.snapshot`文件复制到`bin/cache`目录下，注意，最好先备份原先的`flutter_tools.snapshot`文件。对比文件大小，发现相差很小，那应该稳了，执行`flutter doctor`输出：

Doctor summary (to see all details, run flutter doctor -v):
    [✓] Flutter (Channel stable, 3.3.10, on macOS 13.0.1 22A400 darwin-x64, locale
        zh-Hans-CN)

    • No issues found!

一切正常！?

**2023/01/26更新：注意，修改Flutter SDK文件后，后续使用Flutter命令升级时可能会提示你是否要保留这些改动或出现补充说明3中的报错，一般来说，使用`flutter upgrade --force`命令强制升级即可。**

快写完了，才发现差点忘了一开始是因为什么原因写这篇文章的，按以上解决方案做，如果执行`flutter doctor`命令没问题，实测Android端构建运行也恢复正常了，所以这其实是同一个问题导致的，如果感兴趣的话，可以看看补充分析[Flutter问题记录 - Unable to find bundled Java version（续）][Flutter_ - Unable to find bundled Java version]。

## 补充说明1 ##

如果在Flutter框架项目中没找到Dart SDK，需要先执行命令：

flutter框架项目路径/bin/flutter

执行后，Flutter会自动下载Dart SDK，下载完成后会构建`flutter tool`，也就是生成`flutter_tools.snapshot`快照文件。由于我执行过Flutter命令，所以一开始没注意到项目中默认是不带Dart SDK的。

也许执行命令后你还会遇到这样的问题：

Error: The Flutter directory is not a clone of the GitHub project.
           The flutter tool requires Git in order to operate properly;
           to install Flutter, see the instructions at:
           https://flutter.dev/get-started

解决方法：使用Git工具拉取Flutter框架项目代码，不要直接下载。

## 补充说明2 ##

如果生成`flutter_tools.snapshot`快照文件失败，报错提示：

           ^

执行命令获取`flutter_tools`所需要的依赖包即可解决：

flutter update-packages

## 补充说明3 ##

如果升级Flutter SDK遇到这样的报错提示：

Unknown flutter tag. Abandoning upgrade to avoid destroying local changes. It is
    recommended to use git directly if not working on an official channel.

执行`flutter upgrade --force`命令强制升级即可。

## 总结 ##

写完这篇文章，想着不知道有没有人提issue，要是没人提，我去提一个。没想到，老早就有人提了[issue][]，应该是用Android Studio预览版的人提的，最近也还有人不断在重复提。
