Hibernate ORM is a library providing Object/Relational Mapping (ORM) support
to applications, libraries, and frameworks.

It also provides an implementation of the JPA specification, which is the standard Java specification for ORM.

This is the repository of its source code; see https://hibernate.org/orm/[Hibernate.org] for additional information.

== Continuous Integration

Hibernate uses both https://jenkins-ci.org[Jenkins] and https://github.com/features/actions[GitHub Actions]
for its CI needs. See

* https://ci.hibernate.org/view/ORM/[Jenkins Jobs]
* https://github.com/hibernate/hibernate-orm/actions[GitHub Actions Jobs]

== Building from sources

The build requires at least Java 8 JDK.

Hibernate uses https://gradle.org[Gradle] as its build tool. See the _Gradle Primer_ section below if you are new to
Gradle.

Contributors should read the link:CONTRIBUTING.md[Contributing Guide].

See the guides for setting up https://hibernate.org/community/contribute/intellij-idea/[IntelliJ] or
https://hibernate.org/community/contribute/eclipse-ide/[Eclipse] as your development environment.

== Gradle Primer

The Gradle build tool has amazing documentation.  2 in particular that are indispensable:

* https://docs.gradle.org/current/userguide/userguide_single.html[Gradle User Guide] is a typical user guide in that
it follows a topical approach to describing all of the capabilities of Gradle.
* https://docs.gradle.org/current/dsl/index.html[Gradle DSL Guide] is unique and excellent in quickly
getting up to speed on certain aspects of Gradle.

We will cover the basics developers and contributors new to Gradle need to know to get productive quickly.

NOTE: The project defines a https://docs.gradle.org/current/userguide/gradle_wrapper.html[Gradle Wrapper].
The rest of the section will assume execution through the wrapper.

=== Executing Tasks

Gradle uses the concept of build tasks (equivalent to Ant targets or Maven phases/goals). You can get a list of
available tasks via 

----
gradle tasks
----

To execute a task across all modules, simply perform that task from the root directory. Gradle will visit each
sub-project and execute that task if the sub-project defines it. To execute a task in a specific module you can
either:

. `cd` into that module directory and execute the task
. name the "task path". For example, to run the tests for the _hibernate-core_ module from the root directory
you could say `gradle hibernate-core:test`

=== Common tasks

The common tasks you might use in building Hibernate include:

* _build_ - Assembles (jars) and tests this project
* _compile_ - Performs all compilation tasks including staging resources from both main and test
* _jar_ - Generates a jar archive with all the compiled classes
* _test_ - Runs the tests
* _publishToMavenLocal_ - Installs the project jar to your local maven cache (aka ~/.m2/repository). Note that Gradle
never uses this, but it can be useful for testing your build with other local Maven-based builds.
* _clean_ - Cleans the build directory

== Testing and databases

Testing against a specific database can be achieved in 2 different ways:

=== Using the "Matrix Testing Plugin" for Gradle.

Coming later…

=== Using "profiles"

The Hibernate build defines several database testing "profiles" in `databases.gradle`. These
profiles can be activated by name using the `db` build property which can be passed either as
a JVM system prop (`-D`) or as a Gradle project property (`-P`). Examples below use the Gradle
project property approach.

----
gradle clean build -Pdb=pgsql
----

To run a test from your IDE, you need to ensure the property expansions happen.
Use the following command:

----
gradle clean compile -Pdb=pgsql
----

__NOTE: If you are running tests against a JDBC driver that is not available via Maven central be sure to
add these drivers to your local Maven repo cache (~/.m2/repository) or (better) add it to a personal Maven repo server__

=== Running database-specific tests from the IDE using "profiles"

You can run any test on any particular database that is configured in a `databases.gradle` profile.

All you have to do is run the following command:

----
gradlew setDataBase -Pdb=pgsql
----

or you can use the shortcut version: 

----
gradlew sDB -Pdb=pgsql
----

You can do this from the module which you are interested in testing or from the `hibernate-orm` root folder.

Afterward, just pick any test from the IDE and run it as usual. Hibernate will pick the database configuration from the `hibernate.properties`
file that was set up by the `setDataBase` Gradle task.

=== Starting test databases locally as docker containers

You don't have to install all databases locally to be able to test against them in case you have docker available.
The script `docker_db.sh` allows you to start a pre-configured database which can be used for testing.

All you have to do is run the following command:

----
./docker_db.sh postgresql_9_5
----

omitting the argument will print a list of possible options.

When the database is properly started, you can run tests with special profiles that are suffixed with `_ci`
e.g. `pgsql_ci` for PostgreSQL. By using the system property `dbHost` you can configure the IP address of your docker host.

The command for running tests could look like the following:

----
gradlew test -Pdb=pgsql_ci "-DdbHost=192.168.99.100"
----
