无法为 BuildType_Decorated 获取“applicationVariants”的未知属性

Question

我已经在我的项目中导入了模块并且正确导入了它。但我收到了这个错误。我已经导入了扫描仪控制应用程序模块（斑马）。我已经搜索了许多替代解决方案，但都没有成功。

Error:(36, 0) Could not get unknown property 'applicationVariants' for BuildType_Decorated{name=release, debuggable=false, testCoverageEnabled=false, jniDebuggable=false, pseudoLocalesEnabled=false, renderscriptDebuggable=false, renderscriptOptimLevel=3, minifyEnabled=false, zipAlignEnabled=true, signingConfig=null, embedMicroApp=true, mBuildConfigFields={}, mResValues={}, mProguardFiles=[/home/custom/AndroidStudioProjects/fireball5/fireball/build/intermediates/proguard-files/proguard-android.txt-2.3.3, /home/custom/AndroidStudioProjects/fireball5/fireball/scannercontrol/proguard-rules.pro], mConsumerProguardFiles=[], mManifestPlaceholders={}} of type com.android.build.gradle.internal.dsl.BuildType.

Answer 1

applicationVariants.all 出现错误。

buildTypes {
    release {
        applicationVariants.all { variant ->
            appendVersionName(variant, defaultConfig)
        }
    }
}

修复 1：

这将不起作用，因为您正在申请 apply plugin: 'com.android.library'。

您必须将其更改为 apply plugin: 'com.android.application' 才能使用 applicationVariants.all。

修复 2：

如果您想继续使用apply plugin: 'com.android.library'。

将applicationVariants.all 更改为libraryVariants.all 或testVariants.all。

说明：

applicationVariants（仅适用于应用插件）

libraryVariants（仅适用于库插件）

testVariants（适用于两个插件）

这三个都分别返回 ApplicationVariant、LibraryVariant 和 TestVariant 对象的 DomainObjectCollection。

希望这会有所帮助。
