Description

When building NIFI from scratch the build process raised this issue to me:

[INFO] --- maven-surefire-plugin:2.18:test (default-test) @ nifi-site-to-site-reporting-task ---
[INFO] Changes detected - recompiling the module!

[ERROR] After correcting the problems, you can resume the build with the command
[ERROR]   mvn <goals> -rf :nifi-standard-processors

showing a problem with a dependency that could not be retrieved.

After a bit of investigation I noticed that the dependency is using a capitalised name, in contrast from the one currently being in the repository.

<dependency>
    <groupId>de.svenkubiak</groupId>
    <artifactId>jBCrypt</artifactId>
    <version>0.4.1</version>
</dependency>

vs the definition now in nifi-standad-processors/pom.xml:

<dependency>
 <groupId>de.svenkubiak</groupId>
 <artifactId>jBcrypt</artifactId>
 <version>0.4.1</version>
</dependency>

You can reproduce this issue by forcing maven to retrieve this dependency from the repository, for example removing it from your .m2/repository directory.

This is my first issue reported to the NIFI community, accept my apologies beforehand if I did something not as expected.
