我判斷問題是由於AndroidX和Android support 共存導致

 

在更新一些依賴之后出現

Android dependency 'androidx.core:core' has different version for the compile (1.0.0) and runtime (1.0.1) classpath. You should manually set the same version via DependencyResolution

 

最終解決

在build.gradle文件中添加

中間subprojects這一段

 

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }

    subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex') ) {
                    details.useVersion "27.1.1"
                }

                if (details.requested.group == 'androidx.core'
                        && !details.requested.name.contains('androidx') ) {
                    details.useVersion "1.0.1"
                }
            }
        }
    }
}
