For example, in Mellite:

git clone https://github.com/Sciss/Mellite.git
cd Mellite
git checkout v2.40.0
sbt mellite-app/dumpLicenseReport

gives

If I take the successful example, patterns, and one that fails, fscape, and compare their maven poms, I cannot spot a single difference:

• https://search.maven.org/artifact/de.sciss/patterns-core_2.12/0.15.1/jar
• https://search.maven.org/artifact/de.sciss/fscape-core_2.12/2.31.0/jar

So why do get all these recognition failures?

[Sciss]

any news on this?

[Sciss]

I could narrow down the problem now; it happens when sbt picks up my libraries from ~/.ivy2/local (what happens after you do publishLocal) ; when libraries are retrieved from the Internet to ~/.ivy2/cache, the licenses are correctly parsed.

AFAIK no one has actively worked on this plugin for the last 4~5 years.
Would you be interested in sending a fix for this?

[Sciss]

Sure, I will give the code a look
