ROS Kinetic安卓教程中catkin_make执行失败问题求助

环境信息 #

• Ubuntu 16.04 LTS
• ROS Kinetic
• OpenJDK-8

初始报错 #

按照ROS Android开发环境安装教程的3.1步骤执行catkin_make时，触发Gradle依赖解析错误，控制台输出：

A problem occurred configuring root project 'android_core'.
Could not resolve all artifacts for configuration ':classpath'.
Could not resolve com.android.tools.build:gradle:3.5.2.

project :
Could not resolve com.android.tools.build:gradle:3.5.2.
Could not get resource 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.5.2/gradle-3.5.2.pom'.
Could not GET 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.5.2/gradle-3.5.2.pom'.
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

无效尝试及新错误 #

直接下载gradle-3.5.2.pom放入~/android_core/src/android_core，修改buildscript.gradle中的路径指向该文件，清理项目后重新构建，出现新错误：

script '/home/user/android_core/src/android_core/gradle-3.5.2.pom': 1: unexpected token: < @ line 1, column 1.
     <?xml version="1.0" encoding="UTF-8"?>
     ^
  
  1 error

已尝试更换其他Android Gradle版本，问题仍未解决，求可行的解决方案。
