Error thrown for tutorial code: Can't define method not in interfaces: su

[zhangysh1995]

I was at the step of Installing the DB, and I got the following error:

Caused by: java.lang.IllegalArgumentException: Can't define method not in interfaces: su
        at clojure.lang.Compiler$NewInstanceMethod.parse(Compiler.java:8528)
        at clojure.lang.Compiler$NewInstanceExpr.build(Compiler.java:8058)
        at clojure.lang.Compiler$NewInstanceExpr$ReifyParser.parse(Compiler.java:7959)
        at clojure.lang.Compiler.analyzeSeq(Compiler.java:7106)
        ... 58 more

su is introduced in :

(def dir "/opt/etcd")

(defn db
  "Etcd DB for a particular version."
  [version]
  (reify db/DB
    (setup! [_ test node]
      (info node "installing etcd" version)
      (c/su ; <- here is the error site
        (let [url (str "https://storage.googleapis.com/etcd/" version
                       "/etcd-" version "-linux-amd64.tar.gz")]
          (cu/install-archive! url dir))))

    (teardown! [_ test node]
      (info node "tearing down etcd"))))

I could exec lein run test and everything works fine before adding code for this step. This issue may be related to #441.

I'm running Jepsen inside the provided docker container and here is the environment:

# java --version

Maybe we should consider using a previous release of Debian for the Dockerfile?

I tried to change the os to stretch but it seems many apt install will break on it:

This is a syntax error--changing the operating system isn't going to help. I can't tell from the snippet you've posted why this isn't working, but I suspect it's something to do with putting an (su ...) directly inside a (reify) or (defrecord).--KyleOn Feb 5, 2021 01:50, Yushan ZHANG notifications@github.com wrote: I tried to change the os to stretch but it seems many apt install will break on it: E: Unable to locate package openjdk-11-jdk-headless ERROR: Service 'control' failed to build: The command '/bin/sh -c apt-get -y -q update && apt-get install -qy openjdk-11-jdk-headless libjna-java vim emacs git htop screen pssh curl wget gnuplot graphviz dos2unix' returned a non-zero code: 100

I have re-typed all the code and this error was gone. Thanks for your reply.
