Michael Ellis commented on MJLINK-42:
-------------------------------------
I have the same issue.
*WHEN BUILDING FROM THE COMMAND LINE*
However, when issue the *mvn install* install command from the top level of my
modular project, it works, but when I cs into the *mod-jlink* directory and
perform the *mvn install* it fails with:
```

*WHEN BUILDING FROM NETBEANS IDE*
I get the same failure whether building the overall main project or just the
mod-jlink project.
