the 2.11 jobs are failing, apparently because of some kind of crosstalk between classpaths during Scaladoc generation:

[error] java.lang.NoClassDefFoundError: scala/util/parsing/json/JSONArray

in 2.11, scala-compiler still depended on scala-parser-combinators, that isn't true from 2.12 on

@ashawley did we run into something comparable over in scala-xml?

@eed3si9n is it obvious to you why this might be different in 1.3.0?

is this a repeat/variant of #197 ?

[Philippus]

I think this is the same issue as sbt/sbt#4995.
The workaround mention in sbt/sbt#4995 (comment) works locally for me as well (adding ThisBuild / useCoursier := false).

since only two repos in the world are affected, I think it's fine to go ahead with that workaround. want to do the honors? (you can push additional commits onto scala-steward's branches)

[SethTisue]

I suppose the workaround could be limited to the 2.11 case only, and we leave coursier enabled for the other Scala versions? but whatevs, nbd either way
