Hello, it's not first time when i build a project, in general, this error which you will see become because of Java version/enviroment. Java Enviroment which are required to be added in windows, it is. JAVA_HOME added. In eclipse, i have set java as version to 1.8 ( Java 8u351 ).
This is error which i get which i try to compile Core, for Datapack i don't have any issue. If someone can explain me what's wrong and how i can slve it, i will appreciate.
Thanks and have a good day !
P.S. With this version of eclipse is working
And with version 2022-09 doesn't work !!!! Remember, we speak about the CORE compile! Not the Datapack !
