java - gradle assembleRelease - 在 Windows 上构建 APK 失败

问题描述

使用以下教程创建 APK，但得到BUILD FAILED，附上日志

React Native 项目安装：（ “bulls-n-co”是项目文件夹名称）

npm install -g expo-cli
expo init bulls-n-co
cd bulls-n-co
npm start

创建 APK - 重现步骤：

  1. 以管理员模式运行 CMD

  2. cd c:\Program Files\Java\jdk1.8.0_181\bin

    keytool -genkey -v -keystore release-key.keystore -alias key-alias -keyalg RSA -keysize 2048 -validity 10000

  3. 在此文件夹中生成的 release-key.keystore

  4. 公牛-n-co> npm 运行弹出 （“公牛-n-co”是项目文件夹名称）
  5. 将release-key.keystore复制到bulls -n-co/android/app文件夹
  6. 公牛-n-co> npm i -g react-native-cli
  7. 公牛-n-co> react-native 链接
  8. 在 Bulls-n-co/ gradle.properties文件更新中，注释以下行

org.gradle.configureondemand=true

  1. 在 bulls-n-co/ gradle.properties文件中添加

MYAPP_RELEASE_STORE_FILE=release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=key-alias
MYAPP_RELEASE_STORE_PASSWORD=123456
MYAPP_RELEASE_KEY_PASSWORD=123456

  1. 更新文件 Bulls-n-co/app/build.gradle

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('release-key.keystore')) {
                storeFile file(release-key.keystore)
                storePassword 123456
                keyAlias key-alias
                keyPassword 123456
            }
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

  1. 下载gradle
  2. 解压到 C:\Gradle
  3. 打开环境变量（在 windows 中搜索）并将“C:\Gradle\bin”添加到“Path”
  4. 公牛-n-co\android> gradle assembleRelease
