Error when I want to use file importer (FLL format)

I'm trying to use the next code in Java for Android:

InputStream inputStream = context.getAssets().open("FuzzyRules.fll");
String content = IOUtils.toString(inputStream);
Engine engine = new FllImporter().fromString(content);

The content of file is the example ObstacleAvoidance (I just copy and paste). I validated the content in String and it is correct. I get and error when the Engine is built. The error obtained is:
java.lang.RuntimeException: [import error] expected a colon at here:

Is there any clue about that Error? thanks

Can you please post the FLL code?

Sure, this is the content

#File: ObstacleAvoidance.fll
Engine: ObstacleAvoidance
InputVariable: obstacle
enabled: true
range: 0.000 1.000
lock-range: false
term: left Ramp 1.000 0.000
term: right Ramp 0.000 1.000
OutputVariable: mSteer
enabled: true
range: 0.000 1.000
lock-range: false
aggregation: Maximum
defuzzifier: Centroid 100
default: nan
lock-previous: false
term: left Ramp 1.000 0.000
term: right Ramp 0.000 1.000
RuleBlock: mamdani
enabled: true
conjunction: none
disjunction: none
implication: AlgebraicProduct
activation: General
rule: if obstacle is left then mSteer is right
rule: if obstacle is right then mSteer is left

Could you please debug it? The exception is thrown here:

https://github.com/fuzzylite/jfuzzylite/blob/master/jfuzzylite/src/main/java/com/fuzzylite/imex/FllImporter.java#L109

Not sure what the problem is. Can you check in which line of the FLL the exception is thrown?

This is the error that I get, I don't know if you need more information or do you need I debug using the source corde?

It seems that the problem is an empty line. Would you try removing every empty line in the FLL file?
Otherwise, I am afraid you will need to debug with source code.
