You need to download LibrePlan source code to start hacking on it. You have two options:

a) Clone Git repository (recommended):

`git clone git://github.com/LibrePlan/libreplan.git`

b) Download last version source code here

  • Download latest libreplan_*.war file for your database (PostgreSQL or MySQL) here

You should review this section to check that you have installed all the requirements.


Import LibrePlan project

  • Run Intellij IDEA

  • Select Import Project

  • Select directory with source code of Libreplan (e.g.C:/Users/PC-User/IdeaProjects/libreplan)

  • Select Import project from external model > Maven and click Next

  • Then leave all as default

  • Then select profiles: dev and for PostgreSQL users - postgresql / Mysql users - mysql

  • Then leave all by default

  • Then choose your JDK(SDK), 1.8 strongly preferred

  • Then define project name or leave default name

  • Make mvn clean install in command line


Configure project to run

  • Go to Run > Edit Configurations...

  • Create a new Maven Build called MavenConfig

  • Change the following values:

    • Working directory: Choose libreplan-webapp folder in your workspace
    • Command line: jetty:stop jetty:run
    • Profiles (optional): -userguide -reports -i18n (to disable userguide,reports and i18n profiles to save compilation time as they are not mandatory to run LibrePlan)
    • Mark the following checkboxes (recommended):

Resolve Workspace artifacts

In Before launch section choose + and add Build Artifact (war file)

Click Run and application will be available at http://localhost:8080/


Develop LibrePlan in Intellij IDEA using MySQL

  • The main development focus is on PostgreSQL and this tutorial focusses on PostgreSQL, but if you want to develop LibrePlan using MySQL you have to do 2 small changes:

    • In section Configure project to run_ you have to set the Profiles to: dev mysql -userguide -reports -i18n
  • Remember that the three last profiles that are being disabled is just to save compilation time and not mandatory. However, to develop using MySQL you have to set at least the first two: dev and mysql.
