Could not resolve net.minecraftforge.gradle:ForgeGradle:2.3-SNAPSHOT

[Arknights]

When I run gradlew build or gradlew setupDecompWorkspace, it failed.

Here's the picture.

I have rented a vps and build an ssr myself, but it doesn't work. If I visit the http://files.minecraftforge.net/maven/net/minecraftforge/gradle/ForgeGradle/2.3-SNAPSHOT/maven-metadata.xml through brower directly, nothing appears but the picture below.

And I can't find 2.3-SNAPSHOT in http://files.minecraftforge.net/maven/net/minecraftforge/gradle/ForgeGradle

Is there anyone who meets the same problem? I strongly doubt that there's an web error with the ForgeGradle in minecraftforge. If so, how long would it be before it recovers? If not, what should I do to solve the problem?

A friend told me it's due to certification problem. So how should I deal with it?

DO NOT DO THIS.

Just update Java!
