[mkgmap-dev] Eclipse

Sat Oct 25 10:18:44 BST 2014

Hi Brian,

thanks for the info. I don't know the IvyDE plugin, but it sounds like a 
good solution for us, so I'll try it.
Up to now I maintain the "Java Build Path" manually.

Hi Gerd,
When I run ‘ant resolve’, it downloads and places splitter.jar in './lib/optional/splitter-412.jar’. To use the jar in Eclipse, you can either add it to your classpath or use the IvyDE library. In the patch I made a reference to the IvyDE, but this only works if you have the plugin installed. In Eclipse, my path looks like this:

When I use Eclipse, I let it create it’s workspace in it’s default location. I keep all my projects in a completely different area and then create references to them in Eclipse.If I have multiple branches of a project, I can open them all in the same workspace.
It’s not clear to me how your Eclipse is referencing the jars downloaded from the ‘ant resolve’ phase. 
If it’s simply the .classpath change that is causing difficultly, I’m happy to submit a patch without it. I usually don’t keep the .classpath under version control anyway.

Hi Brian,

I am not sure how to test this patch because my experience with Eclipse is poor.
I did this:
- rename my workingd directory d:\eclipse_workspace to d:\eclipse_workspace_save 
- create new dir d:\eclipse_workspace
- checkout mkgmap r3337 to d:\eclipse_workspace\mkgmap-p
- run ant resolve in that directory
- start Eclipse, switch to the (empty) workspace and use File|New to add project with name mkgmap-p

I expected to get a working version of mkgmap with that procedure, but it seems
that a reference to splitter.jar is missing and 
"uk/me/parabola/mkgmap/reader/dem/optional/" is not marked optional.

I understand the changes in .classpath regarding the jar files, but not the rest.
What changes should I expect?

I am not sure how to handle the dependency on splitter. I think it is okay to use the 
jar file and not the splitter sources as long as one doesn't want to change the splitter
sources. I am not sure that the download link will work in the future.
Regarding the required splitter version: It is much older, don't know if that could be important?

Reg. Ecplipse itself: From time to time I try newer releases, e.g. I tried Keppler and also Luna 4.4.0 and 
moved back to Juno because something regarding debugging did not work (sorry, forgot the details :-(  )

I don’t think my changes make any difference to where you keep your working directory or source, or how you organize your workspace. What specific part of the patch do you think would break your eclipse setup? Can you apply the patch and identify any issues?
