我在这里停留了将近3天，尝试了许多解决方案，但无济于事。我的母语很新。我的代码库如下。
我的settings.gradle看起来像
rootProject.name = 'rnn6'
include ':app'
include ':react-native-navigation'
project(':react-native-navigation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-navigation/lib/android/app/')
我的build.gradle看起来像
buildscript {
ext {
buildToolsVersion = "28.0.2"
minSdkVersion = 19
compileSdkVersion = 28
targetSdkVersion = 27
supportLibVersion = "28.0.0"
}
repositories {
google()
mavenLocal()
mavenCentral()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenLocal()
google()
jcenter()
maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url 'https://jitpack.io'
}
}
}
task wrapper(type: Wrapper) {
gradleVersion = '4.7'
distributionUrl = distributionUrl.replace("bin", "all")
}
subprojects { subproject ->
afterEvaluate {
if ((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
android {
variantFilter { variant ->
def names = variant.flavors*.name
if (names.contains("reactNative51") || names.contains("reactNative55")) {
setIgnore(true)
}
}
}
}
}
}
