What is the behavior if you use the jar file?

Just nothing happens. When I run compiled minecraft, it applies potion effect whenever a player kills a mob. With jar it stands still.

Sometimes it crashed the game with NoSuchMethodException when the src didn't have the method getTrueSource, for example when entity was killed by a block.

That's.... thats not how Java works.

If src did not have that method all the time, your code would not compile

NoSuchMethodException is something thrown by reflection code.

I got this exception when bat suffocated maybe because of gravel. Blocks dont have this method, but living entities do.

But ok let's say there is a problem, then why it works properly when compiled?

Show the stacktrace.

The actual game is obfuscated. When you run the build task, ForgeGradle reobfuscates your mod, updating references to Minecraft's methods and fields. But since you use "getTrueSource" in a string, this will not be updated. In the normal game there won't be a method called "getTrueSource", so your event handler always bails out.

I removed this part and tried to repeat this issue, but seems like everything is working.

That time i got this:crash-2020-05-11_21.37.49-server.txt

Are you using deobfuscated names for reflection, because that's very wrong. If you are replace them with the names from MCP. (Incase you don't know what deobfuscated and obfuscated means,getTrueSource -> func_76346_g)

It's sad how much time mods spend saying "x is no longer supported on this forum. Please update to a modern version of Minecraft to receive support".

They are not. NoSuchMethodError is not something reflection produces.

You did not use the gradle build task to build your mod.
