gradlew build Error (use -source 8 or higher to enable lambda expressions)

Start new topic

Posted December 9, 20222 yr

Im working on a mod and testing it in eclipse runs fine but when I want to turn it into a jar file by running gradlew build I get the Error

error: lambda expressions are not supported in -source 1.6

McR.ex(McR.ex(enderman),3,() -> {});
^

(use -source 8 or higher to enable lambda expressions)

Im using

Gradle 2.7

java version "1.8.0_351"

javac 1.8.0_351

All of my Path and JAVA_HOME environment variable are correct (set to 1.8) and Im not sure what else to check.

In eclipse I did have to say Change project compliance and JRE to 1.8 as this popped up on the lambda error.

The version you are using is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

Currently supported versions are 1.19.2 (Latest) and 1.18.2 (LTS).

How Can I Safely Play an Old Version of Minecraft?

Yeah, you can safely play Beta 1.7.3 using the official Minecraft Launcher. Just create a new installation, pick the old version from the list, and set a separate game directory so it won’t interfere with your current saves. The main compatibility issue is that old saves may break if opened in newer versions, so always back them up.

Mod for world Templates

No, there isn’t a dedicated Forge mod for world templates in 1.20.1. Your options are to use datapacks for custom worlds or run the Fabric mod through Connector.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
