If model has more then 326 cubes the java complier crashes

As title says I am trying to import my blockbench model (614 cubes total) but when exporting or testing mod it gives "BUILD FAILED - Task failed for "compile Java" 

If I remove the cubes of my model it will export without issue and show in game fine
I tried and got to 324 cubes as the highest without it giving this error. 

Is there a workaround so I can import my full model? the 324 model had 0 lag so I don't think it's overloading anything with minecraft itself
