Question

在以前版本的gradle中，我有如下代码，用于为我的发布版本生成outputFileName。

applicationVariants.all { variant ->
        variant.outputs.each { output ->
            output.outputFile = new File(outputPathName)
        }
    }

但是在最后一次gradle更新后，此代码无效。我已阅读官方迁移文档，我应该将代码更改为：

android.applicationVariants.all { variant ->
    variant.outputs.all {
        outputFileName = "${variant.name}-${variant.versionName}.apk"
    }
}

这不起作用。此代码只在/home/pugman/AndroidStudioProjects/clickerapp/app/build/outputs/apk/release目录中创建路径。我也读过这段文字：

“然而，涉及访问outputFile对象的更复杂的任务不再起作用。这是因为在配置阶段不再创建特定于变体的任务。这导致插件不能预先知道它的所有输出，但它也是意味着更快的配置时间。“

这是否意味着上述方法不起作用？

Answer 1

正如你所说，official migration docs表示3.0.0中引入了重大变化。话虽如此，它也清楚地说：

它仍适用于简单的任务，例如在更改期间更改APK名称建立时间

确实它确实:) 但我怀疑你build.gradle可能做错了什么。无论如何，请注意他们在示例中使用applicationVariants作为前缀android：

android.applicationVariants.all { variant ->
    variant.outputs.all {
        outputFileName = "${variant.name}-${variant.versionName}.apk"
    }
}

但是，前缀不需要，除非你在android关闭之外，例如：

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'
    // More stuff here...
}

android.applicationVariants.all { variant ->
    variant.outputs.all {
        outputFileName = "${variant.name}-${variant.versionName}.apk"
    }
}

如果这不能解决问题，那么您最有可能发出的问题是build.gradle中的其他地方。

在你的模块build.gradle.kts
