Problem when compiling the latest version of l2swi

I would like to work with the newer version of l2switch plugin, but when I try to compile the project i get the following errors:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project loopremover-impl: Compilation failure: Compilation failure:

I think the problem isn't in my .m2 folder, since i was able to properly compile the Openflowplugin project. Also i'm using the java 8.0 and my OS is windows 10 (i'm using a plugin of maven to compile via prompt) The command that i'm using to compile is mvn clean install -U -DskipTests

ps: i've not edited any code of the l2switch project, i just imported the master branch from the github repository and tried to compile

l2switch is currently not being maintained by anyone and thus did not participate in the Fluorine release cycle. It needs version bumps and code changes to conform with upstream changes in yangtools, mdsal etc. For the compile errors above, getAugmentation is now augmentation and setKey is now key. These upstream changes were made in Fluorine along with others. This was all documented on the ODL mailing lists and TSC JIRA items during the Fluorine release cycle. Any contributions to reboot the project and get it building again and maintain it going forward would be welcomed by the ODL community.
