Can you access this URL with curl on your computer? https://plugins.gradle.org/m2/me/champeau/gradle/japicmp-gradle-plugin/0.2.8/japicmp-gradle-plugin-0.2.8.pom

I can download this resource without any issue from where I am - I don't see any ongoing problem on https://status.gradle.com/ - so this might be a certificate or proxy issue on your side?

I build spring in windows ,and i can download this file too. i am already put the website certificate to jdk and it doesn't work,now i don't know how to resolve it

At this point the problem is probably not in the Spring Framework build.

There might be a problem with your JDK or a specific proxy configuration.
Do you have a Gradle/JVM HTTP proxy configured? Check c:\Users\your_username\.gradle\gradle.properties.

Maybe a transparent proxy is applied to your connection? You could checking the certificate chain for this domain.

openssl s_client -connect plugins.gradle.org:443

The most likely problem is probably a faulty JDK install with missing CA certificates. See this StackOverflow question.

I'm closing this issue for now as it seems that it's not related to the Spring Framework build but some TLS issue on the developer workstation. Feel free to comment with your findings!
