My Leiningen project was running happily in
- Leiningen 2.5.2
- nREPL 0.2.10
- Clojure 1.8.0
Then I upgraded to Leiningen 2.7.1. Suddenly, I started getting
CompilerException java.lang.annotation.AnnotationFormatError: Invalid default
error on an imported Java class on my :resource-path.
Not quite understanding what happened, I decided to restore back to my working environment by
rm -rf ~/.m2
rm -rf ~/.lein
lein upgrade 2.5.2
Now, based on what lein repl tells me, I am back to my happy environment. Yet, I am still getting the same CompilerException on the same Java class.
This Java class has been a part of a Java application that builds separately from my Leiningen project. The Java application also builds cleanly with OpenJDK 7 and 8. Because of this, I focused on restoring my lein repl environment.
Did I restore the Leiningen env properly? Would you have suggestions on what else I should try?
