I ran the master branch of openmrs-core with `mvn jetty:run`. The server was successfully setup. Then I added the legacy ui module to modules folder and again ran the `mvn jetty:run` command but the following error occured. [https://pastebin.com/RuSGteYJ](https://pastebin.com/RuSGteYJ) ---

@sharif No I am not using the sdk I have cloned the openmrs-core and then I have pasted the `.omod` file in the module folder. This problem occurs only with the master branch. I checkout to `2.3.x` and everything ran perfectly. ---

Am just confused about building the openmrs-core and you have an extension of .omod file. openmrs-core when its packaged ,it is bundled as a war file, forexample “webapp/target/openmrs.war” so for it it has no omod file, then you can deploy your war file in to the application server running like tomcat or jetty. hope am not mistaken can you show us the .omod file extension location in openmrs-core where you pasted the your files thanks again ---

@sharif Maybe I am not able to explain properly Sorry for that . I have successfully run the openmrs-core and it shows either use a UI or RESTAPI. So I want to use the UI I am following [Installing the Legacy UI module](https://wiki.openmrs.org/display/docs/User+Interface+Modules) and this is not working for the master branch but works for `2.3.x` ---
