When I read this "Zip file simpleMod.jar failed to read properly, it will be ignored" I tryed to rename my jar file into a zip but anyway nothing happen.

My mod just have an System.out.println("Hello World"); in the onInit() Event

Here's my mod

 

[birbantik]

I'm using IntelliJ Idea,  Here the jar file

https://mega.nz/#!FjRDSAiB!OkdunrxdPweu-mPB06TZUX5SCJeodq2nAKQ7Q7XHNvU

sorry if I put it on mega.nz but here but here the upload stopped

[Choonster]

You didn't answer diesieben07's question.

 

Did you build the JAR using IDEA's build system or did you build it using the build Gradle task? Only the latter is correct.

[birbantik]

I'm building an artifact, I think I've builded with IDEA build system but how can I change build system?

Run the build task from IDEA's Gradle window or the command line. The compiled JAR will be in build/libs.

[birbantik]

I'm not founding the libs folder in ProjectName/build . Now I'm just pressing build in Intellij but I can't find the jar file.

I'm not using simple intellij IDEA gradle but I'm using an intelliJ IDEA plugin (named Minecraft Dev). Maybe thats the problem

[Choonster]

I'm not familiar with the plugin, do you not have access to the Gradle window?

[birbantik]

Yes I have

[birbantik]

Ok i've tried to build with gradle and it works. Sorry you sad it in your first post
