OK, problem solved. [Removed]

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?
