Getting File name too long when running tests on circleci

Question

Im building my project with circleci 2 and in my test coverage im getting a weird error:

[info] Compiling 5 Scala sources to /root/build/target/scala-2.11/test-classes...
[error] /root/build/test/myApplication/SomeGeneratorNameGen.scala:40: File name too long
[error] This can happen on some encrypted or legacy file systems.  Please see SI-3623 for more details.
[error]     employeeName <- Gen.numStr
[error]                  ^

Answer 1

Your file length is

printf /root/build/test/myApplication/AmountPerExpTypeGen.scala | wc -c
      56

$ printf /root/build/test/myApplication/ | wc -c
      31

Based on the most of the references, you might want to increase the length using scalac options.

eg.

"-Xmax-classfile-name", "242"
