升级API至34后执行./gradlew bundleRelease报错求解决方案

非专业开发者，为家庭使用制作的应用上架Google Play，需将API等级从33升级至34。此前用./gradlew assembleRelease生成APK正常，但执行./gradlew bundleRelease时报错：

BUILD SUCCESSFUL in 6s
75 actionable tasks: 2 executed, 73 up-to-date

FAILURE: Build failed with an exception.

* Where:
Build file '/ssd/chris/AndroidStudioProjects/MyApp/app/build.gradle' line: 183

* What went wrong:
Could not determine the dependencies of task ':app:bundleRelease'.
> Could not create task ':app:bundleDemoRelease'.

问题出在自定义的AAB重命名任务逻辑上——升级AGP适配API 34后，Gradle不允许在任务配置阶段（tasks.configureEach）注册新任务。按以下步骤修改app/build.gradle：

步骤1：删除旧的自定义任务代码 #

找到并删除文件末尾从static String firstMatchingSubstring到tasks.configureEach结束的所有代码，这段代码是：

static String firstMatchingSubstring(String taskName, String[] keys) {
    def lcName = taskName.toLowerCase()
    for(String key: keys) { if(lcName.contains(key.toLowerCase())) return key }
    return null
}

/**
 *
 * @param taskName e.g., bundleMyFlavorRelease or bundleRelease
 * @return
 */
String getBuildType(String taskName) {
    return firstMatchingSubstring(taskName, getBuildTypeNames())
}

/**
 *
 * @param taskName e.g., bundleMyFlavorRelease
 * @return
 */
String getFlavor(String taskName) {
    return firstMatchingSubstring(taskName, getProductFlavorNames())
}

String[] getBuildTypeNames() {
    def types = []
    android.buildTypes.configureEach { type -> types.add(type.name) }
    return types
}

String[] getProductFlavorNames() {
    def flavors = []
    android.productFlavors.configureEach { flavor -> flavors.add(flavor.name) }
    return flavors
}

tasks.configureEach { task ->
    def name = task.name
    //Skip some unnecessary tasks
    if (name.startsWith("bundle")
            && !name.contains("Classes")
            && !name.contains("Resources")
            && name != "bundle") {

        def renameTaskName = "rename${task.name.capitalize()}Aab"
        def version = "${android.defaultConfig.versionName}"
        def flavor = getFlavor(name)
        def type = getBuildType(name)
        if(flavor == null || type == null) return

        def outputName
        if (flavor == "full")
            outputName = "MyApp-$version"
        else
            outputName = "MyApp-$version-$flavor"

        tasks.register(renameTaskName) {
            def path = "${rootDir}/app/${flavor}/${type}/"
            def originalFile = "$path/app-${flavor}-${type}.aab"

            doLast {
                if (file("$originalFile").exists()) {
                    ant.move file: "$originalFile",
                            tofile: "$path/${outputName}.aab"
                }
            }
        }
        task.finalizedBy(renameTaskName)
    }
}

步骤2：添加新的AAB重命名逻辑 #

在android代码块的末尾（比如flavorDimensions += 'app'之后）添加以下代码，统一处理APK和AAB的重命名：

applicationVariants.all { variant ->
    def appName = project.hasProperty("applicationName") ? applicationName : parent.name
    def version = variant.versionName
    def flavorName = variant.flavorName
    def buildTypeName = variant.buildType.name

    // 保留原有的APK重命名逻辑
    variant.outputs.all { output ->
        outputFileName = "${appName}-${version}.apk"
    }

    // 新增AAB重命名逻辑
    def bundleTask = tasks.named("bundle${variant.name.capitalize()}")
    bundleTask.configure {
        it.doLast {
            def outputDir = it.outputs.files.singleFile
            def originalAab = file("${outputDir}/app-${flavorName}-${buildTypeName}.aab")
            if (originalAab.exists()) {
                def newAabName = flavorName == "full" ? "MyApp-${version}.aab" : "MyApp-${version}-${flavorName}.aab"
                ant.move file: originalAab, tofile: file("${outputDir}/${newAabName}")
            }
        }
    }
}

注意：如果原来的APK重命名代码在buildTypes.release块里，可以删除那部分内容，用上面的代码替代，避免重复。

步骤3：执行打包命令 #

保存修改后的build.gradle，执行命令：

./gradlew bundleRelease

此时应该能正常生成重命名后的AAB文件，路径在app/build/outputs/bundle/release/（对应full flavor）和app/build/outputs/bundle/demorelease/（对应demo flavor）。
