Hibernate Maven Plugin – hibernate:drop

hibernate:drop

Full name:

de.juplo:hibernate-maven-plugin:2.1.0:drop

Description:

Generate/Execute SQL to drop all tables of a database-schema that represents the configured mappings.

Attributes:

Requires a Maven project to be executed.
Requires dependency resolution of artifacts in scope: runtime.
The goal is thread-safe and supports parallel builds.
Binds by default to the lifecycle phase: process-classes.

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.hbm2ddl.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`.
execute	`Boolean`	`2.0`	Excecute the generated SQL. 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.execute`.
force	`boolean`	`1.0`	Force generation/execution Force the generation and (if configured) the execution of the SQL, even if no modified or newly added annotated classes where found and the configuration 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`.
mappings	`String`	`1.0.2`	List of Hibernate-Mapping-Files (XML). Multiple files can be separated with white-spaces and/or commas. User property is: `hibernate.mapping`.
outputDirectory	`String`	`1.0`	Classes-Directory to scan. This parameter defaults to the maven build-output-directory for classes. Additionally, all dependencies are scanned for annotated classes. 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`.
outputFile	`String`	`1.0`	Output file. If the specified filename is not absolut, the file will be created relative to the project build directory (`project.build.directory`). Default value is: `drop.sql`. User property is: `hibernate.schema.drop`.
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`.
scanDependencies	`String`	`1.0.3`	Dependency-Scopes, that should be scanned for annotated classes. By default, only dependencies in the scope `compile` are scanned for annotated 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! Default value is: `false`. User property is: `hibernate.schema.scan.test_classes`.
show	`Boolean`	`1.0`	Show the generated SQL in the command-line output. User property is: `hibernate.show_sql`.
skip	`boolean`	`1.0`	Skip execution If set to `true`, the execution is skipped. A skipped execution is signaled via the maven-property `${hibernate.schema.skipped}`. The execution is skipped automatically, if no modified or newly added annotated classes are found and the dialect was not changed. 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!
