随着Gradle 4.10.1和Android Gradle插件的更新3.3.0,我得到以下警告:

警告:API' variantOutput.getPackageApplication()'已过时,已替换为' variant.getPackageApplicationProvider()'.

该行,与周围的上下文(由构建变量分配输出文件名):

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()
            }
        }
    }
}

该迁移指南是不是太有帮助; 虽然variant.outputs.all可能有问题 - 只是不知道要替换什么 - 并且迁移指南指的是任务而不是构建变体.禁用时File ? Settings ? Experimental ? Gradle ? Only sync the active variant,我会得到更多的弃用警告(重点是,这些方法都没有被直接调用): …

我在项目中遇到非常烦人的警告：

WARNING: API 'variant.getMergeResources()' is obsolete and has been replaced with 'variant.getMergeResourcesProvider()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration-avoidance.
REASON: It is currently called from the following trace:

...

WARNING: Debugging obsolete API calls can take time during configuration. It's recommended to not keep it on at all times.
Affected Modules: app

由于该警告将在明年成为错误，因此我想一劳永逸地修复它。

我已经更新了gradle插件，google play服务插件和所有依赖项，但是问题仍然存在。

这是项目级别的build.gradle文件：

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        classpath 'com.google.gms:google-services:4.3.0'
    }
} …

我最近开始使用firebase，并遵循官方指南，为项目添加了一些依赖项才能使用它。这是我添加到新创建的项目中的依赖项：

apply plugin: 'com.google.gms.google-services'
implementation "com.google.firebase:firebase-core:$firebaseCoreVersion"
implementation "com.google.firebase:firebase-auth:$firebaseAuthVersion"


buildscript {
    ...
    ext{
        firebaseCoreVersion='17.0.0'
        firebaseAuthVersion='18.0.0'
    }
}

同步我的项目后，我得到了一个非常糟糕的警告。

WARNING: API 'variant.getMergeResources()' is obsolete 
and has been replaced with 'variant.getMergeResourcesProvider()'.
It will be removed at the end of 2019.

所以，我在gradle.properties中添加了以下代码行，以查看问题所在。

android.debug.obsoleteApi=true

不幸的是，如果我做错了什么，或者我可以做些什么，我从堆栈跟踪中无法理解。

在整个堆栈跟踪下，请先感谢您可以给我的任何评论或答案。
