Leiningen installs but errors on any use

[PhilHudson (Phil Hudson)]

With MacPorts clojure and clojure-contrib installed, here's my abortive install-and-use-leiningen session:

% sudo port -R -u -c install clojure clojure-contrib leiningen

<no errors>

% lein self-install

That's not a task. Use "lein help" to list all tasks.

% lein help install

That's not a task. Use "lein help" to list all tasks.

Exception in thread "main" java.lang.IllegalArgumentException: No implementation of method: :make-reader of protocol:
#'clojure.java.io/IOFactory found for class: nil (jar.clj:17)

at clojure.lang.Compiler$InvokeExpr.eval(Compiler.java:2911)

Following the install instructions on the leiningen site works.

Mac OS X 10.5.8 on 2006 MacBook Pro (dual Intel)
Java 1.6.0_22
MacPorts 1.9.2
Clojure 1.2.0 (MacPorts)

There are some known issues with Leiningen and the MacPorts version of Curl: ​http://osdir.com/ml/clojure/2011-01/msg01054.html

I don't know if this is a fault with Leiningen, Curl, or something else more subtle.

Replying to paul.richards@…:

I think the issue reported by the original poster is different from what I suggest in this comment. Apologies..

[jmroot (Joshua Root)]

Does this still happen with 1.6.1.1?

[ryandesign (Ryan Carsten Schmidt)]

Is this still a problem with leiningen 2.5.0?

[chrstphrchvz (Christopher Chavez)]

This port has since been updated to 2.6.1 (released 2016). Almost 9 years have passed with no update from the reporter; can this be closed?

I see this:

@mf2k, that appears to be a known incompatibility with Java 9 and later: ​https://github.com/technomancy/leiningen/issues/2149. I don’t know if it’s been resolved; leiningen still recommends Java 8.

I think this ticket can be closed, as there’s likely nothing left to do regarding the original issue.

[PhilHudson (Phil Hudson)]

That's fine with me.
