Its most likely due to network or proxy related issue. Please follow the link https://docs.spring.io/spring-boot/docs/current/reference/html/cli-maven-settings.html Also you should set JAVA_TOOL_OPTIONS env variable: -Dhttp.proxyHost=YOUR_PROXY_HOST -Dhttp.proxyPort=YOUR_PROXY_PORT -Dhttps.proxySet=true
