Eclipse M2 Quickstart¶

Check out source code¶

Check out the source code from the git repository.:

git clone git://github.com/geoserver/geoserver.git geoserver

To list the available branches.:

% git branch
   2.15.x
   2.16.x
 * main

Choose main for the latest development.:

% git checkout main

Or chose a stable branch for versions less likely to change often:

% git checkout 2.16.x

In this example we will pretend that your source code is in a directory called geoserver, but a more descriptive name is recommended.

Eclipse Maven builder¶

The maven build supplied with eclipse works with the pom.xml files, however it does recognize some of our custom build steps:

1. Go to Preferences and navigate to Maven ‣ Errors/Warning

2. Change the Plugin execution not covered by lifecycle configuration to Warning.

java-cc-maven-plugin¶

The Eclipse M2 builder does recognize this plugin, build once on the command line first:

1. Navigate to :file:`src/wcs1_1`.

2. Compile, to force the code to be generated:

   mvn compile
   

   [INFO] --- javacc-maven-plugin:2.3:jjtree (jjtree) @ gs-wcs1_1 ---

Import modules into Eclipse¶

1. Use File ‣ Import to open the Import wizard. Select Maven ‣ Existing Maven Projects import wizard, and Next.

2. Define the Root Directory by browsing to the GeoServer src folder.

3. Open Advanced options:

   • Profiles: release

   • Name template: [groupId].[artifactId]

   

4. Press Finish to start import.

   During import use Resolve Later, exclude lifecycle mapping.

   

Run GeoServer from Eclipse¶

1. From the Package Explorer select the web-app module

2. Navigate to the org.geoserver.web package

3. Right-click the Start class and navigate to Run as, Java Application

   

4. After running the first time you can return to the Run Configurations dialog to fine tune your launch environment (including setting a GEOSERVER_DATA_DIR).

Access GeoServer front page¶

• After a few seconds, GeoServer should be accessible at: http://localhost:8080/geoserver

• The default admin password is geoserver.
