Trying to solve this issue

[glorysdj]

it's a compile error, not specifically related to style check
please check if class BuilderParent FieldAccessorTable are in classpath

[Litchilitchy]

Other tests on 2.x, 2.4+, 3.0 all passed. Seems only happens on style check 2.4+ (style check also pass on 3.0)? But in pom there's nothing different with 2.4+ and 3.0

[glorysdj]

please refer to scala/bug#9111
seems to be a scala 2.11 compile bug
not fixed in 2.11, need 2.12

also refer to
