无法在 flutter 中构建 apk，因为在 android/app/build.gradle 中出现错误

Question

当我尝试运行 flutter build apk 时，我无法生成 apk 并且在构建 gradle 中显示错误。

我得到的错误：- 失败：构建失败并出现异常。

• 出了什么问题： 任务“:app:packageRelease”执行失败。

执行 com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable 时发生故障 SigningConfig“release”缺少必需的属性“storeFile”。

• 尝试：

使用 --stacktrace 选项运行以获取堆栈跟踪。 使用 --info 或 --debug 选项运行以获得更多日志输出。 使用 --scan 运行以获得完整的见解。

1m 5s 内构建失败 运行 Gradle 任务“assembleRelease”... 66.5s Gradle 任务 assembleRelease 失败，退出代码为 1

出现上述错误。如何解决？

我的build.gradle文件：-

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader -\>
localProperties.load(reader)
}
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}

检查项目的 Android 文件夹中是否有

key.properties

文件。

我认为这个错误与其相关，因为它是在其中指定的

SigningConfig "release" is missing required property "storeFile".

并确保使用与

variable

文件内的签名配置中写入的相同

build.gradle

名称。

用这个

signingConfigs {
    release {
        keyAlias keystoreProperties['keyAlias']
        keyPassword keystoreProperties['keyPassword']
        storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
        storePassword keystoreProperties['storePassword']
    }
}

并确保你有

keyAlias

=您键入别名

keyPassword

= 您的密钥密码

storeFile

= 密钥存储文件路径

storePassword

= 您密钥存储密码

检查您的

key.properties

文件中是否包含所有这些内容
