Description

Hi,

I'm having trouble building JanusGraph under Ubuntu 18.04 using Java 1.8
and Maven 3.6:

```
git clone https://github.com/JanusGraph/janusgraph.git
cd janusgraph
mvn clean install |& tee log.txt
```

Seems like the in-memory target is not being built when it's needed for some
reason. Any help you can provide about what I'm doing wrong would be
much appreciated. Full logfile attached.

Reproduce the reported command on Ubuntu 18.04 with Java 1.8 and Maven 3.6, then inspect the attached log.txt for why the in-memory target is not built. Done means identifying a reproducible build failure and documenting or fixing the cause, with a successful `mvn clean install`.
