我是 flutter 新手,我正在尝试运行我的第一个项目,而不对演示应用程序的源代码进行任何更改。但我不断收到以下错误:
Launching lib\main.dart on SM A115F in release mode...
Running Gradle task 'assembleRelease'...
FAILURE: Build failed with an exception.
* Where:
Build file 'C:\Users\METRO\StudioProjects\helloworld\android\app\build.gradle' line: ??
* What went wrong:
A problem occurred evaluating project ':app'.
> Could not get unknown property 'keystoreProperties' for SigningConfig_Decorated{name=release, storeFile=null, storePassword=null, keyAlias=null, keyPassword=null, storeType=pkcs12, v1SigningEnabled=true, v2SigningEnabled=true, enableV1Signing=null, enableV2Signing=null, enableV3Signing=null, enableV4Signing=null} of type com.android.build.gradle.internal.dsl.SigningConfig.

我尝试了从升级 gradle 到生成密钥库的所有方法,即使我只是想运行该项目,
这是我的 app\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 FileNotFoundException("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'
}
apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
android {
compileSdkVersion 30
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.helloworld"

versionCode flutterVersionCode.toInteger()
versionName flutterVersionName.toString()
}
signingConfigs{
release {
keyAlias keystoreProperties['key']
keyPassword keystoreProperties['key password']
storeFile keystoreProperties['C:\\Users\\METRO\\key.jks'] ? file(keystoreProperties['storeFile']) : null
storePassword keystoreProperties['store password']
}
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.release
}
}
}
flutter {
source '../..'
}
if (project.hasProperty("MyProject.signing")
&& new File(project.property("MyProject.signing")+".gradle").exists()){
apply from: project.property("MyProject.signing")+".gradle"
}
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()){
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}
这是我的 keystore.properties 文件:
storePassword = store password
keyPassword = key password
keyAlias = key
storeFile = C:\\Users\\METRO\\key.jks
注意:android studio 将 storePassword、keyPassword、keyAlias 前面的警告突出显示为未使用的属性。难道这就是问题所在?如果是的话如何解决?请帮忙。
