Maven build is broken

[cmnrd]

I don't know why this does not show up in CI (perhaps due to the caching of dependencies that is done apparently?), but when I run mvn I get this error:

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:java (mwe2Launcher) on project org.lflang: Execution mwe2Launcher of goal org.codehaus.mojo:exec-maven-plugin:3.0.0:java failed: Plugin org.codehaus.mojo:exec-maven-plugin:3.0.0 or one of its dependencies could not be resolved: Failed to collect dependencies at org.codehaus.mojo:exec-maven-plugin:jar:3.0.0 -> org.eclipse.emf:org.eclipse.emf.mwe2.launch:jar:2.12.2 -> org.eclipse.emf:org.eclipse.emf.mwe2.runtime:jar:[2.12.2]: No versions available for org.eclipse.emf:org.eclipse.emf.mwe2.runtime:jar:[2.12.2] within specified range -> [Help 1]

I tried this also on a fresh clone of LF to be sure that it is not related to any build artifacts that I have, but the error persists.

Looks like deleting ~/.m2 helps, but now I get this:

Ok, apparently mvn package works. But mvn install, which I used, does not work.

Adding the clean flag resolves this issue. So, use mvn clean install. Thanks @housengw for figuring this out!
