IntelliJ QuickStart
===================

.. include:: checkout.txt

Import modules into IntelliJ
----------------------------

#. Run the IntelliJ IDE
#. From the initial panel select ``Open``.

#. Navigate to the ``geoserver/src/pom.xml`` directory and click ``OK``.

#. When asked click on ``Open as a Project``.

#. Optionally, depending on which platform, IntelliJ may ask to ``Trust the Project``.

#. Wait for IntelliJ to ``Sync`` the dependencies, it's possible to follow the process from the ``Build`` tab panel on the bottom.

Finalize the GeoServer Project configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. Click ``File > Project Structure``.

   .. image:: img/intellij_project_structure.png
      :width: 300

#. Update the ``Name`` and select the correct ``SDK`` accordingly to the GeoServer version.

#. Click ``File > Settings``.

      :width: 300

#. From ``Build, Execution, Deployment > Compiler > Annotation Processors``, enable the ``Annotation processing``.

   .. image:: img/intellij_project_settings_annotation_processing.png
      :width: 600

#. Click ``Build > Rebuild Project``.

Run GeoServer from IntelliJ
---------------------------

#. From the Project browser select the ``web-app`` module
#. Navigate to the ``org.geoserver.web`` package
#. Right-click the ``Start`` class and click to ``Modify Run Configuration...``

   .. image:: img/intellij_run.png
      :width: 500

#. It is **important** to correctly set the ``Working directory`` to ``src/web/app``. While having the ``Edit Configurations`` dialog open, fine tune the launch environment (including setting a ``GEOSERVER_DATA_DIR`` or the ``jetty.port``). When settings are satisfactory, click ``OK``.

   .. image:: img/intellij_run_config.png
      :width: 600

#. It's possible now to run GeoServer by selecting ``Run -> Run 'Start'``

Troubleshooting
^^^^^^^^^^^^^^^

#. If there are errors such as "cannot find symbol class ASTAxisId", some generated code is not being included in the build.  Using ``wcs1_1`` as the working directory, run a ``mvn clean install``.
#. In the case of compiler errors like ``java.lang.NoSuchMethodError``, it might be due to ``Error Prone``. This tool is switched off by default, but sometimes it turns on after import to IntelliJ. There are two options to fix it:
    #. Go to Maven tool window and uncheck the ``errorprone`` profile, then click ``Reimport All Maven Projects``:

       .. image:: img/intellij_maven_errorprone.png
          :width: 400

    #. To use ``errorprone``, notably to perform the QA checks, install the ``Error Prone Compiler`` plugin, restart the IDE and set ``Javac with error-prone`` as a default compiler for the project. Please note that this will slow down the build.
#. If there are errors such as "cannot find symbol AbstractUserGroupServiceTest", rebuild the ``security-tests`` project in the security module.  Right-click on the ``security-tests`` project and click Rebuild.
#. In the last versions of IntelliJ Annotations processors are enabled. If there are errors because of this uncheck this option from compiler settings.

#. If IntelliJ complains with an error message like ``Command line is too long.``, click on ``Shorten the command line and run.``

.. note::
   
   If there's a server running on localhost:8080 please check the :ref:`eclipse_guide` for instructions on changing to a different port.

Run GeoServer with Extensions
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The above instructions assume running GeoServer without any extensions enabled. In cases where certain extensions are needed, the ``web-app`` module declares a number of profiles that will enable specific extensions when running ``Start``. To enable an extension, open the ``Maven Projects`` tool and select the profile(s) to enable.

   .. image:: img/intellij_run_profile.png
      :width: 600

The full list of supported profiles can be found in ``src/web/app/pom.xml``.

In order to sync the GeoServer execution with the new modules, from the ``Maven Projects`` tool click the ``Reload All Maven Project`` button (1), then ``Build the Project`` (2) and, once finished, ``Run 'Start'`` (3).

Access GeoServer front page
---------------------------

* After a few seconds, GeoServer should be accessible at: `<http://localhost:8080/geoserver>`_
* The default ``admin`` password is ``geoserver``.
