I have finished a mod and I try to create a jar file that contains the actual mod using gradlew build.

When I do it, it says that build has been done successfully but I don't see any repertory called build/libs so where it is ? or why is it not working ?

yes I have found it but it did not work because I think it missed the main function. So how can I run gradlew build properly ?

I have tried to load my mod on minecraft but it crash and show this crashreport :

le voila

 

switchrail-1.0.jar

when I look into my document it says that it is in fr/mattmouss/switchrail.

how can I have lowercase in all place ? I don't know where I can find the wrong writing

maybe it needn't lowercase in the project name ?

I have found in the directory bin default the wrong case but after changing SwitchRail to switchrail it is not working and sending the same error

when intellij rename file does it work the same way ?

switchrail-1.0.jar

here is the new file with modification. I have moved my main class that were in the main directory switchrail into a sub directory and it had caused failure

that is very strange I don't know how to solve this but indeed that is why it is not working

where does the jar executable search for name of the block ?

 

I have tried with another mod and I think that somehow at a step of my modding I have rename the file SwitchRail

the jar file is created by gradlew ? So gradlew need to search somewhere to define the name "SwitchRail" and i want to know where this uncorrect name is stored in order to delete it and replace it by the correct one

ok gradlew is not working well there is no reason for this to have such a name none of my file has this name and I have already rename the file in IntelliJ and in Windows renaming to something completely different and then renaming to switchrail in lowercase so that is impossible

no it is the one with libs and all this inside ?

where it is ?

ok is it this one ?

ok I delete it and so it will not cause any bug ?

yes it works !! thanks it was not updating the file actually
