The build could not read 2 projects

Hi,

I’m not versed in the world of Java package building, but following the instructions, this fails here:

~/build/jplag $ mvn clean generate-sources assembly:assembly

What am I missing?

Sorry, my fault. A dependency was missing on our Nexus. Please try again - you can now build JPlag directly with all dependencies included in a single jar: run mvn assembly:assembly in the jplag directory. The resulting jar will be jplag.git/jplag/target/jplag-2.11.8-SNAPSHOT-jar-with-dependencies.jar

If anybody else runs into this problem: Build and install jplag.parent first.

After passing -U to mvn, this worked.
