开发Android应用同步Gradle依赖报错：Failed to resolve: redstone.xmlrpc:xmlrpc:1.1.1

Hey Paul, that dependency error is a common hiccup when using libraries that rely on artifacts not hosted in Android's default Google Repository. Let's get this sorted out quickly:

Step 1: Add the Required Repository #

The redstone.xmlrpc:xmlrpc:1.1.1 artifact lives on Maven Central, which isn't always included by default in newer Android projects. You'll need to add this repository to your module-level build.gradle file (the one you shared):

Add this block outside of the android block in your build file:

repositories {
    google()
    mavenCentral() // This line tells Gradle where to find the missing xmlrpc library
}

Step 2: Double-Check Your WordPress-Java Dependency #

Make sure your dependency declaration for the wordpress-java library is properly included in the dependencies block (you didn't share this part, but it's critical):

dependencies {
    // ... your existing dependencies (like support libraries, etc.)
    implementation 'org.wordpress:wordpress-java:4.1.0' // Use the latest stable version available
}

Why This Works #

Android's default setup only pulls artifacts from the Google Repository by default. The redstone.xmlrpc library that wordpress-java depends on isn't hosted there—adding Maven Central gives Gradle the extra location it needs to fetch that missing dependency.

Full Modified Build.Gradle Snippet #

Here's how your updated file should look (I also fixed the truncated proguard path in your release build type):

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.paultoillion.myapplication"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

// Added repository block
repositories {
    google()
    mavenCentral()
}

dependencies {
    // ... your existing dependencies
    implementation 'org.wordpress:wordpress-java:4.1.0'
}

After making these changes, sync your project with Gradle files—this should resolve the missing dependency error.
