Hey, sorry but I have yet another stupid question.
All of my dependencies seem to be correct now, but when I switch from
version 2.4.8 to 2.4.9-RC1, I get this error:
[ERROR] error: missing or invalid dependency detected while loading class
file 'Unmarshaller.class'.
[INFO] Could not access type Unmarshaller in value
akka.http.javadsl.unmarshalling,
[INFO] because it (or its dependencies) are missing. Check your build
definition for
[INFO] missing or conflicting dependencies.
It says in the migration documentation from 2.4.8 to 2.4.9-RC1 that the
package has been moved from akka.http.javadsl.server to the unmarshalling
one shown above.
I can't seem to get around this error no matter what I do.
