[m2e-users] My <packaging>jar</packaging> project won't generate a jar under Kepler/m2e 1.4

I have an eclipse project / Maven module (I'll call it "jsclient") with jar packaging for my web application's client _javascript_.
 
My "webapp" project/module (war packaging) has "jsclient" as a dependency, such that jsclient-{version}.jar is served from the application server's WEB-INF/lib directory.  That is until upgrading to Kepler/m2e 1.4
 
The jsclient-{version}.jar does appear in the magical fakerepo folder, but has 0 bytes.
 
Being a _javascript_ project, I have nothing in src/main/java.  I set my <outputDirectory> to ${project.build.directory}/jar and have an empty <resources></resources> -- I populate the jar directory using a combination of maven-dependency-plugin and exec-maven-plugin, which I have configured in <pluginManagement><lifecycleMappingMetadata>
 
This of course works from the mvn command line and worked in the previous version of m2e.
 
 
I don't know whether these other symptoms are related:
 
  - In my project's properties dialog I see the error
    "The currently displayed page contains invalid values."
    when navigating to the Deployment Assembly section
 
  - The target folder of my jsclient project is often hidden from my Navigator View - this is the first time I've ever seen the Navigator View not show me everything.
 
 
Thanks in advance for any troubleshooting advice.  I'm happy to privately email my full POM.
