Hi,
I am new to eclipse and am having trouble working out how I should
structure my project.
I have an existing java code base that has a src directory, containing
java source files, an obj directory which is where I have currently been
getting javac to place the .class files and a tests directory that
contains several subdirectories, each containing a small java program. The
code in src builds into a library and the programs in tests exercise this
library in various ways.
The way I have imagined it working in eclipse is the whole lot is one
project with multiple targets. The library, built from src, is a target
(producing a jar file) and each test program in tests is a target that
just has the jar file made earlier in its class path. Is this the Eclipse
way of thinking?
If I modify a source file that goes into the making of the library and
then try and run a test program the library needs to be rebuilt. If I use
the debugger on a test program I want to be able to step into the library.
I have been playing around with Project properties etc and I can't seem to
work out how I would create such a setup. I can just hand build ant files
to do it and get Eclipse to call those but that seems to defeat the
purpose of me using an IDE.
Thanks,
Andrew

First take a look at the Product Configuration Tutorial in the Java
Development Users Guide. Here is the online URL:
http://help.eclipse.org/ganymede/topic/org.eclipse.jdt.doc.u ser/gettingStarted/qs-ProjectConfiguration.htm
Eclipse doesn't really have a concept of targets. You should be able to
do what you want with a single project. Define the src and tests
directories as source folders and the obj directory as an output folder.
Eclipse will then compile all of the source (both src and tests) for
you.
You can run each of your tests separately by creating a launch
configuration for each one. The short cut to create a launch is to
select the runnable class (any class with a public static main method),
right click, and select Run as->Java Application from the context menu.
You can edit program arguments from the Run->Run Configurations dialog.
Use the Debug menu to run in debug mode.

Also, if your tests are JUnit tests you can right-click on the class (or
package or project) and choose Run As... > JUnit Test and it will run
the tests.
Hope this helps,
