@ val c = Array.tabulate(9)(_ + 1)
Bad symbolic reference. A signature
refers to JFunction1$mcII$sp/T in package scala.runtime.java8 which is not available.
It may be completely missing from the current classpath, or the version on
the classpath might be incompatible with the version used when compiling the signature.
Compilation Failed
See above. Using tab autocompletion on the Array produces a bad symbolic reference later.
Using https://github.com/com-lihaoyi/Ammonite/releases/download/2.5.5/3.2-2.5.5
A similar error also occurs in Scala's own repl, also related to completion: https://github.com/lampepfl/dotty/issues/15562
I also experienced a similar error. I was test driving the REPL and wrote this:
"hello world".toSeq.map(_.to<TAB>
And got the following stack trace:
