Transient field

Transient field foo should not be included in equals/hashCode contract

This error message shows up if you include a transient field in equals or hashCode. The purpose of transient fields is that they aren’t part of the persisted state of an object. Therefore, they shouldn’t be part of equals either.

This applies to fields marked with Java’s transient keyword, and fields annotated with the JPA @Transient annotations.

If, for whatever reason, you do need to include a transient field in equals or hashCode, you can suppress Warning.TRANSIENT_FIELDS like this:

EqualsVerifier.forClass(Foo.class)
        .suppress(Warning.TRANSIENT_FIELDS)
        .verify();
