android - 找不到参数[1.1]的方法versionCode()

Question

我将versionCode从1.0更改为1.1，如下所示:

versionCode 1.1
versionName "1.1"

现在我无法同步该项目，因为它给了我这个错误:

Caused by: org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method versionCode() for arguments [1.1] on DefaultConfig_Decorated{name=main, dimension=null, minSdkVersion=DefaultApiVersion{mApiLevel=16, mCodename='null'}, targetSdkVersion=DefaultApiVersion{mApiLevel=28, mCodename='null'}, renderscriptTargetApi=null, renderscriptSupportModeEnabled=null, renderscriptSupportModeBlasEnabled=null, renderscriptNdkModeEnabled=null, versionCode=1, versionName=1.10.1, applicationId=com.github.fahadmaqsood.likhat, testApplicationId=null, testInstrumentationRunner=android.support.test.runner.AndroidJUnitRunner, testInstrumentationRunnerArguments={}, testHandleProfiling=null, testFunctionalTest=null, signingConfig=null, resConfig=null, mBuildConfigFields={CRASH_REPORT_EMAIL_ADDRESS=com.android.builder.internal.ClassFieldImpl@b2244504}, mResValues={}, mProguardFiles=[], mConsumerProguardFiles=[], mManifestPlaceholders={}, mWearAppUnbundled=null} of type com.android.build.gradle.internal.dsl.DefaultConfig.

从official docs中，版本代码必须为正整数。

通常，每次有更新时，它将增加1。
