File line length exceeds 100 characters

I meet a problem when I compile spark version 1.3.1. When I compiled the original source codes provided by spark,it was OK. But when I added some source files into the mllib, it came up with errors,like:

• message=File line length exceeds 100 characters

Based on the information at the end of compiling

• [ERROR] Failed to execute goal org.scalastyle:scalastyle-maven-plugin:0.4.0:check (default) on project spark-mllib_2.10: Failed during scalastyle execution: You have 53 Scalastyle violation(s). -> [Help 1]

It should be because of the scalastyle test. I could finish my compile process by closing the validation of scalastyle.

But is there any other ways to handle this problem? I don't think just closing the validation is good enough

Example code of Errors:
good one

val implicitPrefs =  
    new BooleanParam(this, "implicitPrefs", "whether to use implicit preference", Some(false))

bad one

val implicitPrefs = new BooleanParam(this, "implicitPrefs", "whether to use implicit preference", Some(false))

You can also read two code files side by side if their line length has been limited to 80/100.

Scala Style also imposes worthwhile rules like braces around single if-else statements.
