FileBot & Xubuntu 12.04:Unsupported major.minor version 52.0

[^rooker]

Trying to run "FileBot" on Xubuntu 12.04 (64bit).
Throws the following error message:

Exception in thread "main" java.lang.UnsupportedClassVersionError: net/filebot/Main : Unsupported major.minor version 52.0

Seems to be a common issue - because some LTS Distros (like Ubuntu Precise, etc) don't run Java8 yet.

On Ubuntu, you can install it from the OpenJDK-PPA though:

Copying from the tutorial:

Code: Select all

$ sudo add-apt-repository ppa:openjdk-r/ppa
$ sudo apt-get update
$ sudo apt-get install openjdk-8-jdk
$ sudo update-alternatives --config java

Now, if everything went correctly, checking the java version:

Code: Select all

$ java -version

Should return something like this:

openjdk version "1.8.0_72-internal"
OpenJDK Runtime Environment (build 1.8.0_72-internal-b05)
OpenJDK 64-Bit Server VM (build 25.72-b05, mixed mode)

Filebot now runs fine
