为什么 assembleDebug 成功但 assembleRelease 在 react native 中失败？

Question

我已经尝试 assemble 我的项目作为一个版本。但它总是失败。下面是一些我用来构建我的 apk 作为发布的脚本：-

构建成功

.\gradlew assembleDebug --no-daemon
.\gradlew app:assembleDebug

构建失败

.\gradlew app:assembleRelease
.\gradlew assembleRelease -x bundleReleaseJsAndAssets

每次失败构建时提及失败的结果：-

> Execution failed for task ':app:mergeReleaseResources'
> Task :app:mergeReleaseResources
> FAILED cvc-type.3.1.3: The value '' of element 'id' is not valid.

我还尝试使用 keytool 创建密钥库并将其应用于

中的 signingConfigs

./android/app/build.gradle

但没有发布成功。所以，我正在恢复并使用默认 debug.keystore 值

参考论坛的各种答案、SO 问题、我尝试应用的教程。我完全卡住了。

有没有人遇到这个问题并能够克服障碍？

Answer 1

曾经面对过这个，这是一个 APPT2 问题（至少在我的情况下）。从共享的屏幕截图中，它告诉您 重复资源 。这可能发生在您执行 js 捆绑后，并且创建了几个包含资源的文件夹。

以下是我如何处理 APPT2 问题：

尝试导航到 (android/app/build/intermediates/res/merged/release/
看看有没有drawable-*文件夹
执行rm -rf android/app/build/intermediates/res/merged/release/drawable-*)
再试一次./gradlew assembleRelease（你这里可能还是编译失败）
回到同一个文件夹，删除 .DS_Store
再次构建
希望成功

Answer 2

在某些 React Native 版本中，这是一个错误。您可以执行以下操作：

在node_modules/react-native文件夹中，找到react.gradle文件，

然后在doFirst之后添加如下代码：

 doLast {
    def moveFunc = { resSuffix ->
        File originalDir = 
    file("$buildDir/generated/res/react/release/drawable-${resSuffix}");
        if (originalDir.exists()) {
            File destDir = 
    file("$buildDir/../src/main/res/drawable-${resSuffix}");
            ant.move(file: originalDir, tofile: destDir);
        }
    }
    moveFunc.curry("ldpi").call()
    moveFunc.curry("mdpi").call()
    moveFunc.curry("hdpi").call()
    moveFunc.curry("xhdpi").call()
    moveFunc.curry("xxhdpi").call()
    moveFunc.curry("xxxhdpi").call()
}

然后你可以使用./gradlew assembleRelease生成apk。
同时，当你想知道构建过程中的errr是什么的时候，可以使用./gradlew assembleRelease --info commod

Answer 3

我终于可以创建发行版 APK

通过运行命令 keytool -genkey -v -keystore myappkeystore.keystore -alias myappalias-keyalg RSA -keysize 2048 -validity 10000 创建密钥库并将其放置在 .\android\app 上。详细说明可参考here
打开名为 build.gradle 的文件并查找部分名称 signingConfigs

在调试键名后插入以下脚本并替换为您注册的键：-

release {
    storeFile file('mycreatedkeystore.keystore')
    storePassword 'mypassword'
    keyAlias 'mykeyalias'
    keyPassword 'mypassword'
}

打开空白记事本并粘贴以下脚本：-

@echo off
:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
    echo Requesting administrative privileges...
    goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
    echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
    set params = %*:"=""
    echo UAC.ShellExecute "cmd.exe", "/c %~s0 %params%", "", "runas", 1 >> "%temp%\getadmin.vbs"

    "%temp%\getadmin.vbs"
    del "%temp%\getadmin.vbs"
    exit /B

以任意名称保存文件并将扩展名设置为.BAT
将 BAT 文件放在根项目上方的一个文件夹中，例如
- 您的项目文件夹：- C:\Project\Mobile\MyCurrentProject
- 你的批处理文件夹：- C:\Project\Mobile\releaseTool.bat
运行 releaseTool.bat 和构建发布版本的批处理文件

我搜索并找到了几个脚本来完成某些 oart 并将其组合起来为 RELEASE APK 版本制作这个批处理脚本

免责声明：我不是专家，无法详细说明流程或争论我正在做的方式（如果不切实际），因为我未能构建我想要的东西和作品逐个解组合成我提供的。
