How to build

Starting with development of version 4.0, Hibernate uses Gradle as its build tool.

This README describes some of the basics developers and contributors new to Gradle need to know to get productive quickly.

Quickstart

 git clone git://github.com/hibernate/hibernate-orm.git
 cd hibernate-orm
 ./gradlew clean build

If you are having problems with unresolved dependencies you need to configure access to the JBoss Nexus repository (see below).

Executing Tasks

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

gradle tasks

or if using gradle wrapper

./gradlew tasks

Executing Tasks Across All Modules

To execute a task across all modules, simply perform that task from the root directory. Gradle will visit each subproject and execute that task if the subproject defines it.

Executing Tasks In Specific Module

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, in order to run the tests for the hibernate-core module from the root directory you could say gradle hibernate-core:test

Common Java related tasks

build - Assembles (jars) and tests this project
buildDependents - Assembles and tests this project and all projects that depend on it. So think of running this in hibernnate-entitymanager, Gradle would assemble and test hibernate-entitymanager as well as hibernate-envers (because envers depends on entitymanager)
classes - Compiles the main classes
testClasses - Compiles the test classes
jar - Generates a jar archive with all the compiled classes
test - Runs the tests
uploadArchives - Think Maven deploy
install - Installs the project jar to your local maven cache (aka ~/.m2/repository)
eclipse - Generates an Eclipse project
idea - Generates an IntelliJ/IDEA project.
clean - Cleans the build directory
