How to build in eclipse
I am trying to debug a java version in eclipse ... no luck (
I set it up according to:
http://shindig.apache.org/developers/java/build.html
The debugger works as expected.
However if I change the code, the changes are not taken.
"Project -> Build automatically" is checked in eclipse
"Right click on the project -> Run As.. -> Maven build " gives

You can also do this:
cd java/server
mvn jetty:run
This starts a jetty instance running on most resources in place (including content and webapp directories). After you do a build you can press enter to reload the server instance.

My guess is that the jar files get's loaded when the server starts.
So this is why you need to reboot the server.
If I had consistent modification to do on the jar project , I would test
them via unittest classes to validate my changes. After this step, I would
then build the jar and reboot the server.

Re: How to build in eclipse
Posted by Evgeny Bogdanov <ev...@epfl.ch>.
Thank you for the info (I do want the changes on jar projects)
I seem to have found a solution. Though there is still one more problem.
1) My jetty server in eclipse points now to shindig/java/server
2) debugger is linked to this jetty server
3) I use "mvn" command to build the project
Now for the changes to be taken I have to re-run all 3 command above.
Here it sais that normally I have to only rebuild project, and don't
have to restart jetty:
http://shindig.apache.org/developers/java/build.html
Is this the case for you?

Hi,
I am using "war:inplace: for my server project ( which replace the
shindig-server)
THis helps building automatically my code in eclipse and having my changes
ready to test. But if you are doing changes in on the jar projects (gadgets,
social-api, common...) you will need to build them again as Han said.
One example which comes to mind is : changing the container.js in
shindig-common will require running the mvn build command again to have you
jar file updated.

Evgeny,
Shindig is a maven project, setting eclipse build automatically on is not
enough. You will need to run the maven build again to update your changes.
Hope that helps.
