无法解决工件：缺少：

1）org.robolectric：android-all：jar：7.1.0_r7-robolectric-0

尝试从项目网站手动下载文件。

然后，使用以下命令安装它： mvn install：install-file -DgroupId = org.robolectric -DartifactId = android-all -Dversion = 7.1.0_r7-robolectric-0 -Dpackaging = jar -Dfile = / path / to / file

或者，如果您拥有自己的存储库，则可以在那里部署文件： mvn deploy：deploy-file -DgroupId = org.robolectric -DartifactId = android-all -Dversion = 7.1.0_r7-robolectric-0 -Dpackaging = jar -Dfile = / path / to / file -Durl = [url] -DrepositoryId = [ID]

依赖路径： 1）org.apache.maven：super-pom：pom：2.0 2）org.robolectric：android-all：jar：7.1.0_r7-robolectric-0

缺少1个必需的工件。

用于工件： org.apache.maven：超POM：聚甲醛：2.0
