sbt: java.io.UnsupportedEncodingException: UTF-8"

[xiwenc]

I'm getting the following error when I try to import the engine into Intellij 15.0.2.

[info] Loading project definition from /home/../predictionio/engine/project

[error] Use 'last' for the full log.

Can't figure out why or where it is getting UTF-8" (notice the double quote) from. It would be great if someone could help me out here.

Are you following the instructions here? https://docs.prediction.io/resources/intellij/

What is the template you are trying to import, your OS and language? I haven't seen this and use IntelliJ all the time.

BTW if you go to the PredictionIO Google Group will may get other user's help

Yeah I did follow above instructions.

For future reference: I solved the issue by unset-ting all my locale exports prior to starting intelliJ:

$ env | grep UTF
LC_MESSAGES="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LANG=en_US.UTF-8
LC_NAME="en_US.UTF-8"
LC_CTYPE=en_US.UTF-8
LC_ALL=en_US.UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
$ for i in $(env | grep UTF-8 | awk -F= '{print $1}'); do unset $i; done
$ idea.sh
