elasticsearch version: 5.5.2 OS: Windows When I compile elasticsearch source code with gradle, I encountered a problem, such as: - What went wrong: A problem occurred configuring project ':benchmarks'. > Could not resolve all files for configuration ':benchmarks:classpath'. > Could not resolve com.github.jengelman.gradle.plugins:shadow:1.2.3. > Required by: > project :benchmarks > Could not resolve com.github.jengelman.gradle.plugins:shadow:1.2.3. > Could not get resource '[https://plugins.gradle.org/m2/com/github/jeng](https://plugins.gradle.org/m2/com/github/jeng) > elman/gradle/plugins/shadow/1.2.3/shadow-1.2.3.pom'. > Could not GET '[https://plugins.gradle.org/m2/com/github/jengelman/](https://plugins.gradle.org/m2/com/github/jengelman/) > gradle/plugins/shadow/1.2.3/shadow-1.2.3.pom'. > sun.security.validator.ValidatorException: PKIX path building f > ailed: sun.security.provider.certpath.SunCertPathBuilderException: unable to fin > d valid certification path to requested target Can anyone give me some advice?

Hi, something is wrong with your certificate configuration in the JDK as indicated by the error message: ```auto sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target ``` This [Stackoverflow thread provides some pointers](https://stackoverflow.com/questions/21076179/pkix-path-building-failed-and-unable-to-find-valid-certification-path-to-requ).

Hi @saliormoon, you get: > [@saliormoon](#): > > D:\jdk1.8\bin\>java SSLPoke [developer.nrel.gov](http://developer.nrel.gov) 443 > java.net.ConnectException: Connection timed out: connect You cannot even connect to this site from your network and this can have a lot of reasons, e.g. you are behind a proxy and it blocks connections to that host. I get this when I try to connect with curl: ```auto daniel@io:~ $ curl -v https://developer.nrel.gov * Rebuilt URL to: https://developer.nrel.gov/ * Trying 54.164.53.78... * Connected to developer.nrel.gov (54.164.53.78) port 443 (#0) * TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 * Server certificate: developer.nrel.gov * Server certificate: Let's Encrypt Authority X3 * Server certificate: DST Root CA X3 > GET / HTTP/1.1 > Host: developer.nrel.gov > User-Agent: curl/7.43.0 > Accept: */* > < HTTP/1.1 200 OK ``` So I think you need to fix your (Java?) network issues before-hand.

Yes, thanks a lot. I can't access external network and have to use Cntlm to configure some proxy settings. So it's maybe that the proxy settings occur errors. ---
