[error] creating stub for TraversableLike, owner = module class collection#1396, file = /home/jenkins/workspace/dotty-master-validate-partest/ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.11.5.jar(scala/collection/mutable/Builder.class)

Still can't reproduce locally.

When reading Builder, it creates a stub for TraversableLike (which means it did not find it!). Then it dies when trying to apply TraversableLike to type parameters. So the root cause is it did not find TraversableLike.

https://github.com/dotty-staging/dotty/commit/c326d15bce108459371567069a7ecbc38388fb84 got in, could help in debugging this issue.

Looks like it happened again, here's the output with the debugging now in: https://scala-ci.typesafe.com/job/dotty-master-validate-partest/517/consoleFull

stuhood commented 9 years ago

The error Martin is referring to can occur whenever there are two compilation rounds A and B, and transitive dependencies of A are not present during the compilation of B.

A reproduction branch is over here: https://github.com/stuhood/dotty-exp/tree/head-of-empty-repro ... you'll need to modify your bin/dotc script to pass through the -d flag.

Having missing/undeclared dependencies is a really common case for us, so we're very interested in seeing useful, understandable error messages at the point where the type was intended to be used.

odersky commented 8 years ago

I think it has not happened anymore for a number of months. Closing.
