Unable to build nosql-unit

[viswanath7]

When building a project with maven clean install, the build gets stuck at GPG Passphrase.
Furthermore, I had problems generating javadoc.
so I skipped them both by running
mvn clean install -Dgpg.skip=true -Dmaven.javadoc.skip=true
Now, I'm facing compilation errors.
Please help me get pass this step and build it locally.

Using Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
