ClassNotFoundException: clojure.lang.AFunction

binarykitchen commented 7 years ago

This is weird. Few days ago it was working fine, now out of a sudden not anymore. Any boot commands, even invalid ones, do nothing.

boot sdfsdfsdfs just returns an empty line.

but boot --version works fine:

BOOT_CLOJURE_NAME=org.clojure/clojure
BOOT_CLOJURE_VERSION=1.8.0
BOOT_VERSION=2.6.0

and when I run in verbose mode, there is some output but at the end it just does nothing:

I'm experiencing something similar, however I get an error when attempting to build. The boot -v build output ends like this:

Same project builds fine on a linux machine. This also started yesterday after a updating homebrew packages.

binarykitchen commented 7 years ago

when i bumped the boot version from 2.6.0 to 2.7.2 then i dont have that problem anymore.

still, DX could be better here ...

jbondeson commented 7 years ago

Same here. Moving to 2.7.2 seemed to fix whatever it was that got out of whack on macOS.

lwhorton commented 6 years ago

Any word on this? I'm getting a near-identical stack trace to @jbondeson above, but updating to 2.7.2 has not fixed this for me. Perhaps the only difference here is that I'm working with the checkout feature?

martinklepsch commented 6 years ago

For the people who still run into this issue, please post the output of boot -V and the version of boot-bin you installed (probably via your package manager).

lwhorton commented 6 years ago

I'm not exactly sure how to find the version of the boot-bin that's currently installed.

After some tinkering I noticed that this issue was only cropping up when running boot from inside docker. I can't reproduce the error from my local host environment.

Looking through the latest changes didn't highlight anything immediately obvious.

One of the few differences between my host environment and docker environment is that my docker build does not have access to a boot.properties file. Instead I simply pass env variables for things like BOOT_AS_ROOT, BOOT_COLOR, etc. It seems I was missing an explicit BOOT_VERSION 2.7.2 which is normally present in my local boot.properties file. Adding this version flag to the docker environment seems to have fixed the issue. This makes me wonder if the boot-bin/latest/boot.sh is not actually downloading the absolute latest 2.7.2?

martinklepsch commented 6 years ago

Evaluating the below in a repl should print the version of the boot binary you downloaded.

boot.user=> Boot/initialVersion
"2.7.2"

mattfreer commented 6 years ago

I can confirm that I have also just started experiencing this issue. Like @lwhorton I only experience the issue when running boot inside a Docker container.

When boot builds I get the following error:

I'm installing boot with the following Docker command:

RUN curl -fsSLo /usr/local/bin/boot \
  https://github.com/boot-clj/boot-bin/releases/download/latest/boot.sh

I have now got thinks working by adding a BOOT_VERSION env var which seems to have not previously been required by boot-bin. However if I set BOOT_VERSION to the latest version (2.7.2) I continue to experience the problem. But if I specify version 2.7.1 then all works as expected.

Similar problem here on 2.7.2 when running a boot script:

clojure.lang.ExceptionInfo: clojure/lang/Symbol
data: {:file "riddley/compiler.clj", :line 65}
java.lang.NoClassDefFoundError: clojure/lang/Symbol
java.lang.ClassNotFoundException: clojure.lang.Symbol
                                  ...

Unlinking 2.7.2 brew unlink boot-clj and installing 2.5.2 brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/6cf69abd5bd24ff15d62fed6448fddd7a1434f89/Formula/boot-clj.rb solved the problem for me. (2.5.2 was the version I found while quickly looking in the homebrew repo)

So now I have an environment where I can easily switch between working and not working version brew switch ... So if you need additional information with regard to this issue just let me know.

If anyone can provide a minimal repro that'd be really great. I remember running into a similar issue but can't remember how I fixed it or how to reproduce. Admittedly the error here is pretty bad 🙁

When I had this issue, uninstalling boot with brew and clearing the .boot folder fixed it. Perhaps this is a corrupt boot cache issue?

Just ran into this again, noticed that boot.properties had boot set to version 2.6.0

leontalbot commented 6 years ago

Just want to share that, for me, setting in boot.properties

BOOT_CLOJURE_VERSION=1.8.0
BOOT_VERSION=2.7.2

and updating build.boot with [adzerk/boot-cljs "1.7.48-5"] and [adzerk/boot-reload "0.5.2"] solved my issue.
