org.apache.maven.lifecycle.LifecycleExecutionException: Error executing ant tasks

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • We are reporting an issue during the database schema generating process using hbm2ddl tools against some entities using single-table inheritance strategy. It works fine for the simple hierarchy entity mappings. It breaks down when we try to modeling the data using single-table inheritance in relational entities. Here is one example: The main object: @Entity @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorValue("S") public class MySub1 extends AbstractMySuper { @ManyToOne(fetch = FetchType.EAGER) private MySub1 underlying; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy="mysub1") private List<ExcludedMySub1> excludedSub1; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy="mysub1") private List<IncludedMySub1> includedSub1; ... } The relationship super-class: @Entity @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name="myType",discriminatorType=DiscriminatorType.STRING, length=1) public abstract class AbstractMySub1 { @Id @SequenceGenerator(name = "AbstractMySub1", sequenceName = "AbstractMySub1_id") @GeneratedValue(generator = "AbstractMySub1") @Column(precision=5) private int id; @ManyToOne(cascade={CascadeType.PERSIST,CascadeType.MERGE, CascadeType.REFRESH}) private MySub1 mysub1; ... } The relationship sub-classes: @Entity @DiscriminatorValue("I") public class IncludedMySub1 extends AbstractMySub1 { } @Entity @DiscriminatorValue("E") public class ExcludedMySub1 extends AbstractMySub1 { } I got the following error: [hibernatetool] Problems in creating a configuration for JPA.
