在构建签名应用程序时出现“无法解决：org.codehaus.groovy:groovy-all:2.4.12”错误

Question

在 android studio 上，一切正常，还可以构建调试 apk。但是在构建签名应用程序时，会出现此错误。我有可用的互联网连接，我尝试过this question 和其中提到的问题。

它是由统一项目生成的导出文件，因此所有依赖项都在一个 gradle 文件中。就是这样：

    // GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url "https://jitpack.io"
        }

    }

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

allprojects {
    repositories {
        flatDir {
            dirs 'libs'
        }
        google()
        maven {
            url "https://jitpack.io"
        }
    }
}

apply plugin: 'com.android.application'

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'org.codehaus.groovy:groovy-all:2.4.12'

}

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 28
        applicationId 'com.Company.MVPA'
        ndk {
            abiFilters 'armeabi-v7a', 'x86'
        }
        versionCode 1
        versionName '0.1'
    }

    lintOptions {
        abortOnError false
    }

    aaptOptions {
        noCompress '.unity3d', '.ress', '.resource', '.obb'
    }

    buildTypes {
        debug {
            minifyEnabled false
            useProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
            jniDebuggable true
        }
        release {
            minifyEnabled false
            useProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
            signingConfig signingConfigs.debug
        }
    }

    packagingOptions {
        doNotStrip '*/armeabi-v7a/*.so'
        doNotStrip '*/x86/*.so'
    }

}

从答案中添加了这一行：“implementation 'org.codehaus.groovy:groovy-all:2.4.12”，但它显示了上述错误。但没有它，它会显示以下错误（仅在构建签名 apk 时）：

如何构建一个签名的apk来解决这个问题？

Answer 1

将 jcenter 添加到存储库中，在实现行中。

allprojects {
    repositories {
        jcenter() //this
        flatDir {
            dirs 'libs'
        }
        google()
        maven {
            url "https://jitpack.io"
        }
    }
