[SOLVED] I can't create a new block

Whenever I wanna create a block and I finish creating it, this error appears in the console:

> Task :compileJava FAILED
C:\Users\felli\MCreatorWorkspaces\fellinaters_dimensions\src\main\java\net\mcreator\fellinatersdimensions\init\FellinatersDimensionsModBlocks.java:17: error: cannot find symbol

FAILURE: Build failed with an exception.

I did basic block creations (Adding a texture, name, configuring stuff like I always did) and this is the first time It shows this

[SOLVED]:

I simply didn't replaced the plugins and the mcreator.bat file.
