Combine Coverage from test and it:test

[pme123]

I created a Stackoverflow Question:

https://stackoverflow.com/questions/54349427/scoverage-combine-coverage-from-test-and-ittest?noredirect=1#comment95514180_54349427

As I got no answer, I wonder if this is maybe something that is not supported by scoverage at all?

@pme123 can you remove sbt-buildinfo plugin from your build and check if it works.

@gslowikowski, I have the same problem, and I'm not using sbt-buildinfo.

Using sbt 0.13.18. Here's my plugins.sbt:

addSbtPlugin("org.scalatra.sbt" % "scalatra-sbt" % "0.3.5")

addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.3")

addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.5.1")

I'm running:

sbt clean coverage test it:test coverageReport

And these are extracts of the build output:

At the end the reports contain only the coverage for it:test. We can see that it does "Cleaning datadir" before running them.

Can you please help?

Hmmm...

[info] Generating myproject/target/scala-2.11/resource_managed/main/rebel.xml.

Is it generated by sbt-jrebel-plugin (or a fork)?

[ericbn]

@gslowikowski, good point. I removed that and still there's code being compiled and datadir is being cleaned before test and it:test:

Is the extra compilation to myproject/target/scala-2.11/classes before it:test causing the datadir to be cleaned and code re-instrumented? If yes, then any idea what might be causing that extra compilation?

Thanks!

It seems that the actual issue here was fixed. If not, please do comment back and re-open.

[ckipp01]

This same issue was just reported on gitter, so reopening since this seems to still be the case.
