[kepler-dev] GIS workflow and display

[David Welker]

Hi Chris,

One thing to keep in mind is that if you develop your own module, you do 
not necessarily need to convince others to upgrade to a new jar right 
away. What you can do is just use the jump-1.2.jar in your new module, 
and it will be used not only for any additional work you do, but by 
Kepler itself. (But, people doing unrelated work that do not use your 
new module will still use the jump-1.1.jar.) This should be fine as long 
as version 1.2 is backwards compatible. Additionally, keep in mind that 
even if version 1.2 is not completely backwards compatible, you can 
override the Kepler classes that are not backwards compatible in your 
module without actually touching those classes in the core module. 
Ultimately, if your changes make sense, they can be merged into the core 
of Kepler. But, from your perspective, you do not need to wait or engage 
in any sort of complicated negotiation process to add a module that will 
use Kepler with your preferred version of this jar. That is one of the 
major advantages of the build system that Kepler now uses.

Let me know if you have any questions about this process.
