Flutter 在 Android 上构建失败，但没有明显的错误消息

Question

最近升级了 flutter 的版本和导入的各种包后，我正在尝试构建我的应用程序。这对于 iOS 模拟器来说效果很好，但不适用于在 Android 上运行。我在构建中不断遇到失败，但我看不到明显的错误消息来指示出了什么问题。你能给我一些指点吗？

在此处构建输出：

Launching lib/main.dart on Pixel 6a in debug mode...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileFlutterBuildDebug'.
> A problem occurred starting process 'command '/Users/neill.bowler/Development/flutter/bin/flutter''

* Try:

> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

* Get more help at https://help.gradle.org

（我在android studio的gradle编译器选项中设置了--stacktrace和--debug，但这似乎不起作用）

Answer 1

我已经设法解决了我自己的问题。我做了三件事，结合起来似乎很有效。

选择一个较新的项目，并将设置从
```
android/build.gradle
```
和
```
android/app/build.gradle
```
复制到现有项目。下面粘贴了更新的文件以获取信息。
升级将我切换到了较新版本的JAVA（然后需要更新的gradle版本，这导致了一堆问题）。我通过设置JAVA_HOME强制使用旧版本的JAVA，通过：
```
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Home
```
。
当时我在 dexing（文件大小缩小）方面遇到了很多问题。通过将最低 Android SDK 从 21 更新到 24 解决了这个问题。

我一直在命令行中使用

flutter run

。使用

flutter -v -d "Pixel 6a" run

有时非常有帮助，有时会使屏幕变得混乱。非常感谢罗伯特的建议。

更新了 android/build.gradle:

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = "../build"
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(":app")
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

更新了 android/app/build.gradle:

plugins {
    id "com.android.application"
    id "kotlin-android"
    // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.
    id "dev.flutter.flutter-gradle-plugin"

if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader("UTF-8") { reader ->
        localProperties.load(reader)
    }
}

def flutterVersionCode = localProperties.getProperty("flutter.versionCode")
if (flutterVersionCode == null) {
    flutterVersionCode = "62"
}

def flutterVersionName = localProperties.getProperty("flutter.versionName")
if (flutterVersionName == null) {
    flutterVersionName = "62"
}

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file("key.properties")
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {

        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdk = 24
        targetSdk = flutter.targetSdkVersion
        versionCode = flutterVersionCode.toInteger()
        versionName = flutterVersionName
    }

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

            signingConfig signingConfigs.release
        }
    }
}

flutter {
