An error to find a sources/jar file should not stop project file generation

[galderz]

In one of my builds, sources/javadoc for an antlr library is missing:

[warn]  [NOT FOUND  ] antlr#antlr;2.7.7!antlr.jar(src) (192ms)
[warn] ==== public: tried
[warn]   http://repo1.maven.org/maven2/antlr/antlr/2.7.7/antlr-2.7.7-sources.jar
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  ::              FAILED DOWNLOADS            ::
[warn]  :: ^ see resolution messages for details  ^ ::
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  :: antlr#antlr;2.7.7!antlr.jar(src)
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

Even though it's a WARN, the project is not correctly generated and the SBT scala compiler is not correctly set in the IDEA project.

This is with sbt-idea 1.6.0 and scala 2.11.2

The only workaround is to do: sbt "gen-idea no-classifiers", but then you don't have source/javadocs for any of the other libraries :(
