Gradle 同步失败 - 解析失败：appcompat-v7:26

Question

我在 app/build.gradle.

中使用此代码

  android {
        compileSdkVersion 26
        defaultConfig {
            applicationId "com.avizhegroup.android.dsmmaps"
            minSdkVersion 21
            targetSdkVersion 26
            versionCode 2
            versionName "1.1"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
        useLibrary 'org.apache.http.legacy'
    }



repositories {
        maven {
            url "https://jitpack.io"
        }
    }

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:26.1.0'
    implementation 'com.google.android.gms:play-services-maps:11.0.4'
    implementation 'com.android.volley:volley:1.1.0'
    implementation 'uk.co.chrisjenx:calligraphy:2.3.0'
    implementation 'com.github.zookey:universalpreferences:0.0.4'
    implementation 'com.google.android.gms:play-services-location:11.0.4'
    implementation 'com.jakewharton:butterknife:8.8.1'
    implementation 'com.github.bosphere.android-filelogger:filelogger:1.0.3'
    implementation 'com.afollestad.material-dialogs:core:0.9.6.0'
    implementation 'com.orhanobut:logger:2.2.0'
    implementation 'com.orhanobut:logger:2.1.1'
    implementation 'com.orhanobut:dialogplus:1.11@aar'
    implementation files('libs/usbdriver.jar')
    implementation files('src/main/libs/rlmotgusbdriver.jar')
    implementation 'me.imid.swipebacklayout.lib:library:1.1.0'
    implementation 'com.felipecsl.asymmetricgridview:library:2.0.1'
    implementation 'com.readystatesoftware.sqliteasset:sqliteassethelper:+'
}

我在同步时遇到问题 Gradle。出现了这些问题：

ERROR: Failed to resolve: design

我在首选项中取消选中实验中的变体，更改依赖项，更改 SDK 版本，更改等级版本和...。此代码在 windows 中有效，但在 Mac 中无效。
我使用约束布局和 AndroidStudio3.3.2
我该如何纠正？
谢谢

Answer 1

将 google maven 添加到您的根目录 build.gradle，如下所示：

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        google()

    }
}

我遇到了一些问题，尝试改变
compileSdkVersion 26 到 compileSdkVersion 28

然后如果需要再回到 26
