opening link from browser results in Cloudflare page requesting captcha. i can access repository from browser, but maven cannot use browser's cookies and cannot enter captcha.

how can i use it?

Looks like it's working from my end. it may have been having connectivity issues before. Can you try again?

works great. not sure what you're issue is. are you trying to crawl the endpoint multiple times in a script or something? what country are you accessing from?

@Skiftcha - this looks like it's an issue between you and cloudflare. The resources uses cloudflare to prevent DDoSing and you may have been blacklisted by cloudflare. I suggest contacting them to see if you have been blacklisted and check if that can be fixed.

@Sleaker, i think it is not cloudflare problem, they work correctly in browser because i can type captcha and use site.
i just think cloudflare is not intended to be used with maven repositories or other stuff which should be accessed from command line. it is for websites. because maven cannot prove that i am human.

@Skiftcha I don't get the are you human pop-up, nor do any of the automated services we use. As I mentioned in my above response this could be a result of your IP block getting blacklisted by cloudflare to force you proving you're human anytime you're accessing a resource behind a cloudflare IP.

i asked question on cloudflare forum but i think they can not help me.
there is no whitelist features or sudh option in cloudflare
i can not control will or will not cloudflare ask me captcha. it may depend on my country, or subnetwork, or anything else

so putting maven repository behind cloudflare you (or repository owner) prevent some people from using it. or you force us to use proxies/vpn (which should likely be blocked my cloudflare as well)

@Skiftcha you can download it manually and install it into your maven cache locally if you need to. no need to use the remote repository. or you can host your own mirror of it.
