在 flutter 项目的 BitBucket 上构建管道

Question

我在 bitbucket 上为我的 android 项目创建了管道，这些管道非常棒！ 我正在尝试为我的 flutter 项目做同样的事情！ 我第一次将它上传到 bitbucket 中，项目构建完美，工件也安装和播放！

从第二次开始，我收到一个我无法理解的错误。 （我在构建 gradle 和 bitbucket 上的 .yml 上都没有更改项目中的某些内容。

这是我得到的错误：

    FAILURE: Build failed with an exception.

这是我的 bitbucket.yml

     - step:

            - flutter clean

            - echo 'Building Finished'
          artifacts:
            -  build/app/outputs/flutter-apk/**

这是我的 app/build.gradle：

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'
}

def keystorePropertiesFile = rootProject.file('key.properties')

        checkReleaseBuilds false
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "example.project.flutter"

//            keyPassword keystoreProperties['keyPassword']

            signingConfig signingConfigs.debug
//            signingConfig signingConfigs.release
            minifyEnabled true
            shrinkResources false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.core:core:1.3.1'
    implementation 'com.google.firebase:firebase-messaging:21.0.1'
    implementation 'com.google.firebase:firebase-analytics:18.0.3'
    implementation 'com.android.support:multidex:1.0.3'
    implementation("com.google.android.gms:play-services-fitness:20.0.0")
    implementation("com.google.android.gms:play-services-auth:19.0.0")
}

请记住，我不想将我的 sdkversion 设置为 31。我想将其保持在 30。我不明白为什么它第一次起作用，而其他时候却没有？ 你能帮我么？

Answer 1

听起来您对级别为 31 的 SDK 有依赖关系，但在您的项目中使用级别为 30 的 SDK。您可以：

1. 找到使用 31 级 SDK 的依赖并降级；
2. 为您的项目设置 31 级 SDK。

对于第二种解决方案，它可能类似于这样：

android {
    compileSdkVersion 31

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
        checkReleaseBuilds false
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "example.project.flutter"
        minSdkVersion 25
        targetSdkVersion 31
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }
    // ...
}

Answer 2

所以是的，我做了一个对我很有效的改变。

在 app/build.gradle 我添加了这个小家伙：

configurations.all {
        resolutionStrategy { force 'androidx.window:window-java:1.0.0-alpha10' }
    }

这实际上强制了库的特定版本。 在我的错误中，您可以看到它说由于该依赖关系而崩溃：

Dependency: androidx.window:window-java:1.0.0-beta04.
