Position Error: Enclosing tree [2507] does not include tree [2506]

[richard-w]

What: sbt clean coverage test fails, while sbt clean test succeeds
Version: 1.3.5
How to reproduce: Checkout richard-w/azas revision 60c3ff751630e7ff377bf5ed1f663f2cb99db23d and run sbt clean coverage test

Full error output (note that scalariform complains too):

[ymeymann]

Having the same issue

[akara]

This post reflects the same issue, with a workaround. Might be a similar use case.

[ymeymann]

Thanks @akara, the workaround fixed the issue for me.

[xuanzhaopeng]

I could provide more information:
Scala : 2.11.8
SBT: 0.13.12
scoverage: 1.3.5

Same error.

[sksamuel]

This is a bug with the scalac plugin. I'll create a ticket over there.
