External jars are not loaded by forge loader

[guyguann]

Hello,

I'm facing some issues when i'm building my mod. I followed this [wiki section]https://github.com/MinecraftForge/ForgeGradle/wiki/Dependencies#packaging-dependencies-with-mod-file
As you can see in the *gradle.build*, I need to include 2 jars in my mod. The build step is ok but when I'm starting my minecraft server, it tells me that `java.sql.SQLException: No suitable driver found for jdbc:mariadb://localhost:3306/minecraft`, meaning that the JDBC driver for mariadb is not taken in account by the forge loader. I suppose my gradle configuration is incorrect but can't figure out what to modify.
I'm using the jar located in builds/libs.

I also tried `com.github.johnrengelman.shadow` plugin and  it's not working. I'm kind of surprised there is no 1 good example for that kind of issues.

Let me know if you need more details.

Oh ok, I see...
You said "There is no good way" but does a solution exist?
