hibernate:drop

Full name:

de.juplo:hibernate-maven-plugin:2.0.0:drop

Description:

Goal which extracts the hibernate-mapping-configuration and exports an according SQL-database-schema.

Optional Parameters

Name	Type	Since	Description
createNamespaces	`Boolean`	`2.0`	Specifies whether to automatically create also the database schema/catalog. Default value is: `false`. User property is: `hibernate.hbm2dll.create_namespaces`.
delimiter	`String`	`1.0`	Delimiter in output-file. Important: This configuration value can only be configured through the `pom.xml`, or by the definition of a system-property, because it is not known by Hibernate nor JPA and, hence, not picked up from their configuration! Default value is: `;`. User property is: `hibernate.schema.delimiter`.
dialect	`String`	`1.0`	Hibernate dialect. User property is: `hibernate.dialect`.
driver	`String`	`1.0`	SQL-Driver name. User property is: `hibernate.connection.driver_class`.
export	`Boolean`	`2.0`	Export the database-schma to the database. If set to `false`, only the SQL-script is created and the database is not touched. Important: This configuration value can only be configured through the `pom.xml`, or by the definition of a system-property, because it is not known by Hibernate nor JPA and, hence, not picked up from their configuration! Default value is: `true`. User property is: `hibernate.schema.export`.
force	`boolean`	`1.0`	Force execution Force execution, even if no modified or newly added annotated classes where found and the dialect was not changed. `skip` takes precedence over `force`. Important: This configuration value can only be configured through the `pom.xml`, or by the definition of a system-property, because it is not known by Hibernate nor JPA and, hence, not picked up from their configuration! Default value is: `false`. User property is: `hibernate.schema.force`.
format	`Boolean`	`1.0`	Format output-file. User property is: `hibernate.format_sql`.
hibernateConfig	`String`	`1.1.0`	Path to Hibernate configuration file (.cfg.xml). If this parameter is specified, the plugin will try to load configuration values from a file with the given path or a ressource on the classpath with the given name. If both fails, the execution of the plugin will fail. If this parameter is not set the plugin will load configuration values from a ressource named `hibernate.cfg.xml` on the classpath, if it is present, but will not fail if there is no such ressource. During ressource-lookup, the test-classpath takes precedence. Settings in this file will overwrite settings in the properties file.
hibernateProperties	`String`	`1.0`	Path to a file or name of a ressource with hibernate properties. If this parameter is specified, the plugin will try to load configuration values from a file with the given path or a ressource on the classpath with the given name. If both fails, the execution of the plugin will fail. If this parameter is not set the plugin will load configuration values from a ressource named `hibernate.properties` on the classpath, if it is present, but will not fail if there is no such ressource. During ressource-lookup, the test-classpath takes precedence.
implicitNamingStrategy	`String`	`2.0`	Implicit naming strategy User property is: `hibernate.implicit_naming_strategy`.

Important: This configuration value can only be configured through the `pom.xml`, or by the definition of a system-property, because it is not known by Hibernate nor JPA and, hence, not picked up from their configuration! User property is: `project.build.outputDirectory`.

password	`String`	`1.0`	Database password User property is: `hibernate.connection.password`.
persistenceUnit	`String`	`1.1.0`	Name of the persistence-unit. If this parameter is specified, the plugin will try to load configuration values from a persistence-unit with the specified name. If no such persistence-unit can be found, the plugin will throw an exception. If this parameter is not set and there is only one persistence-unit available, that unit will be used automatically. But if this parameter is not set and there are multiple persistence-units available on, the class-path, the execution of the plugin will fail. Settings in this file will overwrite settings in the properties or the configuration file.
physicalNamingStrategy	`String`	`2.0`	Physical naming strategy User property is: `hibernate.physical_naming_strategy`.
scanClasses	`Boolean`	`2.0`	Wether the project should be scanned for annotated-classes, or not This parameter is intended to allow overwriting of the parameter `exclude-unlisted-classes` of a `persistence-unit`. If not specified, it defaults to `true` User property is: `hibernate.schema.scan.classes`.

Multiple scopes can be seperated by white space or commas. If you do not want any dependencies to be scanned for annotated classes, set this parameter to `none`. The plugin does not scan for annotated classes in transitive dependencies. If some of your annotated classes are hidden in a transitive dependency, you can simply add that dependency explicitly. Default value is: `compile`. User property is: `hibernate.schema.scan.dependencies`.
scanTestClasses	`Boolean`	`1.0.1`	Whether to scan the test-branch of the project for annotated classes, or not. If this parameter is set to `true` the test-classes of the artifact will be scanned for hibernate-annotated classes additionally. Important: This configuration value can only be configured through the `pom.xml`, or by the definition of a system-property, because it is not known by Hibernate nor JPA and, hence, not picked up from their configuration!
