It seems failed to download a file ( ForgeGradle:2.3-SNAPSHOT:20180601.071940-30 )
when I use browser open this link ( Could not get resource 'http://files.minecraftforge.net/maven/net/minecraftforge/gradle/ForgeGradle/2.3-SNAPSHOT/ForgeGradle-2.3-20180601.071940-30.jar'. ),it also failed.
How to solve it?
