Server loads as vanilla server without any mods?

[__crispyy__]

Hi, I downloaded the forge installer and setup a 1.12.2 forge server. Everything seems to work except the mods I have installed; there are around 50 in the "mods" folder but none load when the server actually starts? When i join on a forge account i can see the mods' stuff in the creative menu, but when i go to place anything it quickly disappears. The server runs fine other than that. Does anyone know what might be the problem? thankyou for any help

Make sure you start the forge server jar

Hi, there are 2 jar files in the folder. "minecraft_server1.12.2", which starts the server but no mods, and "forge-14.23.5.2860", which when i open with jar, causes the cursor to do the loading circle for a few second and then nothing happens?

Make sure you have Java 17 installed

Then create the start.bat file

Into it, paste:
 

"C:\Program Files\Java\jdk-17.0.9\bin\javaw.exe" -Xmx4G -Xms2048M -jar forge-14.23.5.2860.jar
pause

Keep the quotation marks and make sure the Java path is correct

Start the server with the bat file

Firstly, Java 17 is not required for Forge in Minecraft version 1.12.2, instead it can be deadly to run a 1.12.2 server with Java 17, use Java 8!! Use the correct Java 8 path for the server and you should be good to go!

For my use, I am using Eclipse Temurin Java, which you can download relatively easy!

Here you have my start arguments when starting Forge server 1.12.2!

"C:\Program Files\Eclipse Adoptium\jre-8.0.392.8-hotspot\bin\javaw.exe" -Xmx4G -Xms4G -jar forge-1.12.2-14.23.5.2860.jar
pause

As I am using Java JRE not Java JDK, please use the version that is best for you!

With best regards

Oh wait - Use java 8 instead of Java 17
