For uDig development a few changed to default Eclipse preferences settings will be needed.

Run/Debug > Launching (Eclipse 3.3.1.1 Only)

Apply your Changes

Please start up Eclipse (as described in the previous step).

Java > Code Style > Coding Template

The code template supplies the default header header for udig project files, and offers a great starting place for your javadocs.

From the eclipse menu bar select Window>Preferences
In the Preferences Dialog navigate to the page Java>Code Style>Code Templates
Press the 'Import ...' button
- Select the file:
  C:\java\udig\trunk\extras\net.refractions.udig.dev\codetemplates.xml
  (from the doc project you checked out earlier)

Or downloaded directly from svn: http://svn.refractions.net/udig/udig/trunk/extras/net.refractions.udig.dev/codetemplates.xml

Confirm that the uDig header is available for "New Java Files" as shown.

Java > Code Style > Code Formatter

Rather than burden you with a bunch of coding conventions we are making use of the Eclipse Code Formatter.

Open up Windows>Preferences and Navigate to Java>Code Style>Formatter
Press the 'Import ...' button
- Select the file:
  C:\java\udig\trunk\extras\net.refractions.udig.dev\codeformatter.xml
- Or downloaded directly from svn:
  http://svn.refractions.net/udig/udig/trunk/extras/net.refractions.udig.dev/codeformatter.xml
Confirm that the the profile is named uDig 1.0 as shown.

Java > Compiler

The default java compiler settings do not work for the udig application, you will need to change these before your first build.

Open up Window>Preferences and Navigate to Java>Compiler
On the 'Compliance and Classfiles' tab change the following:
- Compiler compliance level: 1.5
Everything else will be defaulted as required

Java > Compiler > Building

Open up Window>Preferences and Navigate to *Java > Compiler > Building
Toggle to arrow next to Output folder and add .svn to the list of Filtered Resources

Note that missing this step would double your build times!
Java > Compiler > Errors/Warnings

We are interested in making the following change:

Code style	Level
Non-externalized strings (missing/unused $NON_NLS$ tag)	Warning

Open up Window>Preferences and Navigate to Java> Compiler > Errors/Warnings
Open the Code Style category and change to match the following:

Java > Installed JREs

We need to ensure that you picked up a JRE with JAI and ImageIO included:

Open up Window > Preferences and navigate to Java > Installed JREs
Select your JRE from the list and press Edit
Ensure JRE system libraries includes the following jars:
- jai_codec.jar
- jai_core.jar
- jai_imageio.jar
If they are not there you can fix this using the "Add External JARs" button. You should find these jar files the jre/lib/ext/ folder. If they are not there check that you installed JAI and ImageIO are use a search utility to find them.
Here is what that looks like:
Optional: To make Javadocs available while developing select the rt.jar above and press the Source Attachment... button. You can select a src.jar from any JDK on your system.

Plug-in Development > Compilers

Keep extension point documentation current:

Open up Window>Preferences and Navigate to Plug-in Development>Compilers
On the 'Schemas' tab check Generate reference documentation from schemas

Optional Settings For Working Around Problems

Run/Debug > Launching (Eclipse 3.3.1.1 Only)

Recommended if you have a slow machine (or as a workaround for an Eclipse 3.3.1.1 problem with automatic build running multiple times prior to launch).
