Error on doing yt tutorial https://youtu.be/Mt0DsdRezaQ

'_persistence_getRelationships()' in 'com.haulmont.chile.core.model.impl.AbstractInstance' clashes with '_persistence_getRelationships()' in 'org.eclipse.persistence.internal.weaving.PersistenceWeavedRest'; attempting to use incompatible return type
screenshot below (different example than in tutorial but with the same result):

Any ideas?

Please follow these instructions to set proper JDK (8 or 11 are supported):
