org.gradle.api.tasks.TaskExecutionException

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.

  • First create simple entities to be enhanced. {code:java} import javax.persistence.*; import java.util.List; @Entity public class Author { @Id @GeneratedValue private Long id; @OneToMany(fetch = FetchType.LAZY, mappedBy = "author") private List<Item> items; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public List<Item> getItems() { return items; } public void setItems(List<Item> items) { this.items = items; } } {code} {code:java} import javax.persistence.*; @Entity public class Item { @Id @GeneratedValue private Long id; private String content; @ManyToOne(fetch = FetchType.LAZY) private Author author; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public Author getAuthor() { return author; } public void setAuthor(Author author) { this.author = author; } } {code} If we try to enhance it with hibernate-gradle-plugin version 5.2.1.Final with following configuration as suggested by official documentation. {code:none} hibernate { enhance { enableLazyInitialization = true enableDirtyTracking = true enableAssociationManagement = true enableExtendedEnhancement = false } } {code} We fail with an exception {code:none} org.gradle.api.tasks.TaskExecutionException: Execution failed for task
