Trouble writing plugins in Eclipse

[Ned Horning]

Hi – I am trying to learn to write plugins in Eclipse to run in Fiji and
have run into a problem I haven't been able to figure out. I am writing
a plugin that needs to access other plugins such as Extract SIFT
Correspondences, Extract SIFT Correspondences, and bUnwarpJ. I searched
the list archives and found similar questions but nothing that quite
answered my question.

Following the ImageJ Eclipse HowTo instructions
(http://imagejdocu.tudor.lu/doku.php?id=howto:plugins:the_imagej_eclipse_howto)
I was able to create another plugin that performs as expected in ImageJ
with the plugin appearing under the plugin menu. For the more complex
plugin I get an error “Plugin or class not found: SIFT_ExtractPointPoi”.
I get the same error trying to access the Extract SIFT Correspondences
plugin from the ImaegJ plugin menu. To add the Extract SIFT
Correspondences plugin I copied the mpicbg_.jar file to the IJ/plugins
directory. In the plugin I'm trying to run Extract SIFT Correspondences
using IJ.run().

I then tried to build fiji using the Developing Fiji in Eclipse
instructions (http://fiji.sc/wiki/index.php/Developing_Fiji_in_Eclipse).
I can get fiji to run but for some reason some .jar files (such as
compat.jar, fiji-lib.jar, fiji-scripting.jar, Script_Editor.jar...)
mysteriously disappear from the fiji/jars and fiji/plugins directories
so I have to keep replacing them for it to run again. In any case, when
it is running I haven't been able to figure out how to develop my new
plugin in fiji using eclipse. When fiji launches from Eclipse I don't
see my plugin listed in the plugins menu.

In summary I have found the plugin tutorials to be helpful but I can't
figure out how to develop and debug a plugin using Eclipse that accesses
another plugin. I have some experience writing scripts that access
plugins but I'd like more flexibility.

Any advice is welcome.

All the best,

Ned

We have recently finished updating the Fiji build system to be compatible
with Maven. This has a number of advantages, one of which is the ability to
import Fiji plugins into Eclipse as Maven projects (File > Import >
Existing Maven Projects). Note that you will need the "Eclipse for Java
Developers" distribution with Eclipse 3.7 or later (4.2 works fine too)—or
else you can install the M2E plugin manually into your Eclipse.

To have your plugin depend on another plugin, simply add the other plugin
as a Maven dependency in your pom.xml file (Eclipse has a graphical POM
editor that helps with this).

See the updated "Developing Fiji in Eclipse" page for further details:
    http://fiji.sc/Developing_Fiji_in_Eclipse

In general, using Maven with your ImageJ plugin allows others to more
easily reuse and build on your code.

The ImageJ1 source code is also available for use with Maven from:
    git://github.com/fiji/imageja.git

If you clone that link and then import into Eclipse (again: File > Import >
Existing Maven Projects) you will see that the dependent Fiji plugins
automatically change from a library dependency on ij.jar to a project
dependency on the source code.

Please let us know if you have any questions or problems with it!

Regards,
Curtis
