Re: sbt exportJars causes "lengthLimitInBits.>=(0)" error when running "sbt test"

[Olabusayo Kilo]

I was also able to recreate this error in the CSV repo by adding the 
"exportJars := true" (note: false doesn't cause this error),

and updating the Daffodil version to the last commit before the RC 
commit (i.e 613c2b0c077f56dbb425e7ebab1a2d154cbdbd06).

so:


exportJars :=true libraryDependencies ++=Seq(
  "org.apache.daffodil" %%"daffodil-tdml-processor" %"3.3.0-SNAPSHOT" %"test",
---
)

So it seems to be a Daffodil error, since this doesn't happen with 
3.0.0, but it does happen with 3.2.1

Note: I'm running sbt 1.5.7 (Ubuntu Java 11.0.14), but I believe Mike 
tried several different versions when we first ran into this.

I tried many things, including clean git clones of all related repos. This
problem is a very bizarre interaction.

The fact that the tests ran flawlessly under intelliJ IDEA, but failed
running sbt from the command line

I searched for sbt bugs related to exportJars. I did find
https://github.com/sbt/sbt/issues/3119, but doesn't seem related or not
obviously so.

I can confirm that at least sbt clean does not resolve the issue.  Didn't
try a got clean, although I had just cloned the repo in question so I don't
think it had gotten dirty in anyway either.

That's surprising to me. All that exportJars is supposed to to do is
include or not include certains files on the class path and use packages
jars instead.

And that assertion that is failing is beacuase the length of test data
is negative, which should never happen and I don't know how exportJars
would affect that.

It almost sounds like something got corrupted or needed to be rebuilt,
and changing exportJars allowed that to happen? Maybe there's some
conflict between using IntelliJ and sbt at the same time?

I wonder if doing an sbt clean or git clean would resolve the issue.

We noticed that only when running "sbt test" in schema projects with the
exportJar setting, the error below was generated resulting in failure of
all the tests. Note that running the same tests via IntelliJ/Junit
didn't reproduce this error, and the error was isolated to using sbt to
run the tests.

The cause was isolated to having the "exportJars := true" setting in
build.sbt. Removing the setting removed the error, and got all tests
passing. Sending this out as an FYI in case someone else runs into this
in the future.
