gradle - variantOutput.getPackageApplication()已过时

Question

将Gradle 4.10.1和Android Gradle插件更新为3.3.0，我得到以下警告:

WARNING: API 'variantOutput.getPackageApplication()' is obsolete and has been replaced with 'variant.getPackageApplicationProvider()'.

该行以及周围的上下文(通过build变体分配输出文件名):

applicationVariants.all { variant ->
    variant.outputs.all { output ->

        if (variant.getBuildType().getName() in rootProject.archiveBuildTypes) {

            def buildType = variant.getBuildType().getName()
            if (variant.versionName != null) {

                def baseName = output.baseName.toLowerCase()
                String fileName = "${rootProject.name}_${variant.versionName}-${baseName}.apk"

                // this is the line:
                outputFileName = new File(output.outputFile.parent, fileName).getName()
            }
        }
    }
}

migration guide不太有用；尽管 variant.outputs.all可能有错-只是不知道要替换什么-迁移指南仅涉及任务而不是构建变体。禁用 File → Settings → Experimental → Gradle → Only sync the active variant时，我会收到更多的弃用警告(要点是，这些方法都没有被直接调用):

WARNING: API 'variant.getAssemble()' is obsolete and has been replaced with 'variant.getAssembleProvider()'.
WARNING: API 'variantOutput.getProcessResources()' is obsolete and has been replaced with 'variantOutput.getProcessResourcesProvider()'.
WARNING: API 'variantOutput.getProcessManifest()' is obsolete and has been replaced with 'variantOutput.getProcessManifestProvider()'.
WARNING: API 'variant.getMergeResources()' is obsolete and has been replaced with 'variant.getMergeResourcesProvider()'.
WARNING: API 'variant.getMergeAssets()' is obsolete and has been replaced with 'variant.getMergeAssetsProvider()'.
WARNING: API 'variant.getPackageApplication()' is obsolete and has been replaced with 'variant.getPackageApplicationProvider()'.
WARNING: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders()'.
WARNING: API 'variantOutput.getPackageApplication()' is obsolete and has been replaced with 'variant.getPackageApplicationProvider()'.

问:如何通过迁移到新的API来避免这些过时的警告？

Answer 1

variantOutput.getPackageApplication()由更改的变体API引起。

changing output.outputFile.parent to variant.getPackageApplicationProvider().get().outputs.files[1] is at least a temporary workaround.

variant.getExternalNativeBuildTasks()由 io.fabric插件引起。

the next version of the io.fabric plugin will use variant.getExternalNativeBuildProviders().

资料来源: 116408637; confirmation用于 promise 的修复( 1.28.1)。

这些是由 com.google.gms.google-services引起的:

registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

'variant.getMergeResources()' is obsolete and has been replaced with 'variant.getMergeResourcesProvider()'

这个 blog post解释了如何通过添加该插件生成的XML资源来完全摆脱 com.google.gms.google-services插件。从 build/generated/res/google-services/debug/values/values.xml到常规 debug/values/values.xml。

最简单，最省力的方法可能是:

buildscript {
    repositories {
        google()
        maven { url "https://maven.fabric.io/public" }
    }
    dependencies {
        //noinspection GradleDependency
        classpath "com.android.tools.build:gradle:3.2.1"
        classpath "io.fabric.tools:gradle:1.28.1"
    }
}

有关调试信息: ./gradlew -Pandroid.debug.obsoleteApi=true mobile:assembleDebug
这些 warnings均未以任何方式改变行为。
