无法在代码中导入 gradle 库，尽管它出现在我的外部库列表中

Question

我正在尝试将 kSOAP2 导入到我的应用程序中。我使用他们的说明通过 Maven 导入并尝试使用 Gradle 翻译它。它显示在外部存储库列表中，但是当我尝试添加 import com.google.code.ksoap2-android.ksoap2-android.3.6.4 时找不到。

这是我的 build.gradle

apply plugin: 'com.android.application'


android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.mylocationjava"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    maven { url 'https://oss.sonatype.org/content/repositories/ksoap2-android-releases/' }
    mavenCentral()
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    implementation files('libs\ksoap2-android-3.6.4.jar')

    implementation 'com.google.code.ksoap2-android:ksoap2-android:3.6.4'
}

Answer 1

包名称不一定是您需要导入的 class 的名称（通常不是）。要找到要导入的 class 的名称，请进入包 jar 并检查那里的 class 名称是什么，或者在线查看使用示例。

示例：

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

我是这样做的：

build.gradle（模块）：

dependencies {
    implementation 'androidx.appcompat:appcompat:1.4.1'
    implementation 'com.google.android.material:material:1.5.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
    implementation 'androidx.preference:preference:1.1.1'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'com.google.code.ksoap2-android:ksoap2-android:3.6.4'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'

settings.gradle:

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://oss.sonatype.org/content/repositories/ksoap2-android-releases/' }
    }
}
rootProject.name = "idt.pda"
include ':app'

    }

无法在代码中导入 gradle 库，尽管它出现在我的外部库列表中
