Building error [Probably DependencyResolutionException]

[GABRYCA]

Maven version isn't found for this plugin, i'm trying 3.0.1-SNAPSHOT and 3.0.2-SNAPSHOT but nothing

2.1.1-SNAPSHOT it's the only working

[GABRYCA]

Sorry, i fixed this by changing the spigot repository from public to snapshot:
<repository> <id>spigot-repo</id> <url>https://hub.spigotmc.org/nexus/content/repositories/snapshots/</url> </repository>

No, another error, changing the title, please help me.

When i build with maven:

I get that error, i'm using the version 3.0.1-SNAPSHOT

[Terminal-Access]

This error is because maven now denies access to any repo's that have not moved to using secure web protocal "https" as you can see from the repository address above its insecure, and the owner of the website has not set up a valid certificate if you try and switch the URL to "https" this is a huge issue however luckly ther is a work around within maven.

Update - Fix 1
Have found that the ".com" tld for this repository has a valid cert and look to be a complete mirror of the ".be" repo.
so simply switching the url and protocall will allow you to rebuild again.

Step 1: replace the ".bd" domain TLD with the ".com" domain TLD "MVdWPlaceholderAPI"

<url>https://repo.mvdw-software.be/content/groups/public/<url/>

Step 2: Change To:

<url>https://repo.mvdw-software.com/content/groups/public/</url>

Long term fix for .be domain:
Author/website owner of the ".be" domain TLD will need update the domain to use "https" and a valid ssl certificate. (for ssl certs look in to letsencrypt, they are free! and widly supported now.)

Hope this helps!

This error is because maven now denied access to any repo's that have not moved to using secure web protocal "https" as you can see from the repository address above its insecure, and the owner of the website has not set up a valid certificate if you try and switch the URL to "https" this is a huge issue however luckly ther is a work around within maven.

Quick Fix:
Add the following to your .m2 settings.yml - in the section:

<mirror>
	<id>mvdw-software-mirror</id>
	<mirrorOf>mvdw-software</mirrorOf>
	<url>http://repo.mvdw-software.be/content/groups/public/</url>
	<blocked>false</blocked>
</mirror>

"false" Tells maven to allow insecure http protocal use, this will allow you to use the repo again when building projects.

Long term fix:
Author/website owner will need update the domain to use "https" and a valid ssl certificate. (for ssl certs look in to letsencrypt, they are free! and widly supported now.)

Hope this helps!

Not a problem, your very welcome, I have just updated my reply above with an alt quick fix that dosent require editing the .m2 settings.yml file.

Have a great day!
