Hi everyone, I'm new to opendaylight and I want to hack odl-l2switch code to add some functionalities. As the user guides and wiki say, I pulled the code from git clone git clone .

Then I coded the necessary changes and used

mvn clean install

to build the code. It was successful. Afterwards when I ran the karaf in the folder,


the odl-l2switch-switch feature was with the snapshots which were not built by me. It was with some other downloaded jars. How can I build my code for l2switch and run it with distribution karaf?

Thanks for taking time

Hi ,

It has to take L2switch's own version if you launch L2switch/distribution/karaf/target/assembly/bin (I believe). Because It refers the same project version for all the L2 features .

Which version are you using and which version is installing?

In which module have you modified? (hostTracker/loopRemover/arphandler etc) . Add some log messages in your modifications and check it out in log file.

Hi karthik, I used latest and its showing 4.0 in snapshots. Both the build for the codes and distribution folder shows 4.0. I coded in main-impl and arphandler. And I made some logs in others too. But log does not return any thing. How can I hack the code and test its behavior for odl-l2switch?

the log only shows for openflowplugin.impl logs

Did you created new class or modified the existing code? If new class,then you have to instantiate it. You mentioned "Both" the build, It means l2switch and ODL-Distribution? Its easy to hack the code, I dont understand your full context.

No karthik I hacked the code. But then I thought mvn clean install will replace the l2switch code with the ones that I have modified. But it wasn't. I used the gerrit repo for l2switch. Instead I copied the built jars again to the system directory and then it worked. Any suggestions?

i clone from github -> ; when i do mvn clean install it will replace my old code with modified code in .m2 local repository.
