[Bug] Errors encountered while installing dependencies and setting up OpenDF

[Kalyan3578]

I followed the guide to installing dependencies on Wiki page, and surprisingly I wasn't able to install Java. When you execute sudo apt-get install openjdk-7-jdk, the terminal must show this error:

I thought about this for awhile and tried going on with an updated version, and the result was unexpected but it worked.

Instead of executing sudo apt-get install openjdk-7-jdk, change the '7' to '8' and try again.

sudo apt-get install openjdk-8-jdk

I tried it and it worked well.

The second error that is, when I run mvn install:install-file -Dfile=sleuthkit/bindings/java/dist/Tsk_DataModel.jar -DgroupId=org.sleuthkit -DartifactId=Tsk_DataModel -Dversion=4.1.3 -Dpackaging=jar as stated on the 'Installation' section on Wiki, it shows me the following error:

I don't understand what this is about, maybe Java but I'm not sure. I'd like to know the fix to complete my installation.
