mvn liquibase:generateChangeLog, and when I try to execute the diff command with mvn liquibase:diff I get an error message Error getting default schema java.lang.NullPointerException. Not sure what's wrong with my configuration. I am testing Liquibase 3.6 with Spring Boot and Spring JPA@Entity
@Table(name = "user", uniqueConstraints = {
@UniqueConstraint(name = "uk_login_user", columnNames = { "login" }),
@UniqueConstraint(name = "uk_email_user", columnNames = { "email" })
})
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@NotNull
@Pattern(regexp = Constants.LOGIN_REGEX)
@Size(min = 1, max = 50)
@Column(length = 50, nullable = false)
private String login;
@Size(max = 100)
@Column(length = 100)
private String email;
}
