General

...

To develop on Daffodil using Eclipse, you will need Eclipse with the Scala IDE add-ins. Versions from 4.5 (Mars) seem to work acceptably.

You will need the Java SDK (not just the JRE), and Daffodil requires Java 8 (aka 1.8) at least.

The daffodil tree includes a sub-directory called eclipse-projects. These can all be imported to Daffodil

An Eclipse 'Linked Resource' named DAFFODIL_ROOT must be defined to be the path to the clone of the git repository for Daffodil.

These projects are all set up to use a common lib_managed project directory that is an Eclipse link to the DAFFODIL_ROOT/lib_managed which is populated using sbt. See the note below about "pre-build with sbt".

Pre-build with sbt to Retrieve Libraries

Before starting Eclipse, you must issue the 'sbt updateClassifiers compile' command. This pulls down all libraries needed, and puts them into lib_managed where the eclipse projects are setup to find them. This also pulls down all the source and javadoc jars for convenient access. The compile command forces some code-generator steps to run which create source code in the daffodil-lib module.

Build Macro Lib First

Before building the rest of the Daffodil modules, you must first build daffodil-macro-lib. This defines macros that are used in the other modules.
