## 解决方案

打开应用的build.gradle文件，可以看到配置如下：

```groovy
apply plugin: 'com.huawei.ohos.app'

ohos {
    compileSdkVersion 7
    defaultConfig {
        compatibleSdkVersion 6
    }
}

buildscript {
    repositories {
        maven {
            url 'http://repo.ark.tools.huawei.com/artifactory/maven-public/'
        }
        maven {
            url 'http://mirrors.tools.huawei.com/maven/'
        }
    }
    dependencies {
        classpath 'com.huawei.ohos:hap:3.0.3.1'
    }
}

allprojects {
    repositories {
        maven {
            url 'http://repo.ark.tools.huawei.com/artifactory/maven-public/'
        }
        maven {
            url 'http://mirrors.tools.huawei.com/maven/'
        }
    }
}

其中，http://repo.ark.tools.huawei.com/artifactory/maven-public/ 和 http://mirrors.tools.huawei.com/maven/ 这两个仓库地址是不能正常从外网访问的。

将上述地址做下替换即可。

apply plugin: 'com.huawei.ohos.app'

ohos {
    compileSdkVersion 7
    defaultConfig {
        compatibleSdkVersion 6
    }
}

buildscript {
    repositories {
        maven {
            url 'https://repo.huaweicloud.com/repository/maven/'
        }
        maven {
            url 'https://developer.huawei.com/repo/'
        }
    }
    dependencies {
        classpath 'com.huawei.ohos:hap:3.0.3.1'
    }
}

allprojects {
    repositories {
        maven {
            url 'https://repo.huaweicloud.com/repository/maven/'
        }
        maven {
            url 'https://developer.huawei.com/repo/'
        }
    }
}

这个时候可能又会报另外一个错误

A problem occurred configuring root project 'SimpleGalleryETS'.
> Could not resolve all artifacts for configuration ':classpath'.
  > Could not find com.huawei.ohos:hap:3.0.3.1.
    Searched in the following locations:
      - https://repo.huaweicloud.com/repository/maven/com/huawei/ohos/hap/3.0.3.1/hap-3.0.3.1.pom
      - https://developer.huawei.com/repo/com/huawei/ohos/hap/3.0.3.1/hap-3.0.3.1.pom
    Required by:
        project :

Possible solution:

• Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

那么这时，将版本号升级改为com.huawei.ohos:hap:3.0.3.4 即可。
