A workaround is to use jenv: #298

Could this be as simple as upgrading JRuby in build.sbt?

jruby/jruby#4558 (comment)

My experience figuring out how to use jenv as a workaround, for anyone having trouble:

#298 (comment)

I just used Docker, problem solved.

Here is what I did:

1. Created a s3_website directory on my app root directory
2. There I created 3 files:

Dockerfile

FROM ruby:2.3.3

RUN apt-get update -qq && \
    apt-get install --assume-yes -y \
       build-essential \
       libpq-dev \
       openjdk-7-jre \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

# Use en_US.UTF-8 as our locale
ENV LC_CTYPE en_US.UTF-8
ENV LANG en_US.UTF-8

# Run bundle
RUN gem install s3_website && s3_website install

RUN mkdir /app
VOLUME /app
WORKDIR /app

CMD bash

build.sh

#!/bin/bash
docker build -t utils/s3_website .

deploy.sh

#!/bin/bash

docker run --rm \
    --name s3_website \
    -it \
    -v "$(cd .. && pwd):/app" \
    utils/s3_website \
    s3_website push

And I still keep the s3_website.yml file in my app root folder. The app container will access it through a shared volume.

The process is simple:

1. Install Docker
2. $ bash build.sh # just need to do it once to create the image
3. $ bash deploy.sh # loads info from ../s3_website.yml

Note: I am sure that this process can be optimized, e.g., let --dry-run be parameter for deploy.sh, but so far it works well for me.

I tried and failed to make a PR to fix. I know basically nothing about Scala or Java, so no real surprise. Notes:

• Tried to run ./sbt assembly, failed with error around Missing dependency 'object java.lang.Object in compiler mirror'. Googling seems to suggest this is likely a result of sbt being too old for java 9 (0.13.2).
• Tried to replace project/sbt-launch.jar with 0.13.7 downloaded from SBT website. Failed with error module not found: org.scala-sbt#sbt;0.13.17. This appears to be same actual error as Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty #312, workaround posted there. Command now works, but "assembly" not a valid command.
• Switched to a project I have an pointed it at local s3_website with path: option in bundler. Still getting error: scala.reflect.internal.MissingRequirementError: object java.lang.Object in compiler mirror not found. when trying to publish.
• Turns out something created project/build.properties which was locking SBT version (./sbt sbtVersion) to 0.13. Updated that to 1.1.6 (latest). No cannot resolve sbt-assembly and sbt-idea dependencies, pretty sure those are specified somewhere in this project.
• Updated sbt-assembly to latest and removed sbt-idea (for now). Commented out code to fix error: not found: object AssemblyKeys (this will very likely burn me later), sbtVersion now reports 1.1.6.
• publishing still results in object java.lang.Object in compiler mirror not found :(

#300 (comment) I would also recommend using asdf to manage different versions of java on your mac. It's a meta manager so it can also manage ruby, nodejs, elixir, erlang, ...

That's how I "fixed" this issue on my machine.

For searchability:

Caused by: java.lang.RuntimeException: unsupported Java version: 10

Got a colleague with the same problem except their runtime exception message is unsupported Java version: 11

Your build dependencies currently indicate that jRuby 1.7.11 is required. jRuby's Github indicates that the latest versions support up to v10: https://github.com/jruby/jruby/blob/ce15c9d63e7312c47c7d86c2852e93a406459c7b/core/src/main/java/org/jruby/RubyInstanceConfig.java

For my future self:
Problem:

Caused by: java.lang.RuntimeException: unsupported Java version: 11
	at org.jruby.RubyInstanceConfig.initGlobalJavaVersion(RubyInstanceConfig.java:1878)

Solution:

PATH=/usr/lib/jvm/java-8-openjdk-amd64/bin/:$PATH s3_website push

Can confirm that @losomo's workaround worked for me on Ubuntu 18.04 with openjdk-8-jre-headless package installed.

> lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.1 LTS

openjdk-8-jre-headless:amd64: /usr/lib/jvm/java-1.8.0-openjdk-amd64

So which Java versions are supported? Can we at least mention that in the Readme? I'd hate to download and install one after the other until I hit one that's supported...

I ended up brewing down to adoptopenjdk8 (Java 8) in order to get this plugin to work.

Annoying because I had to completely uninstall adoptopenjdk11.

I'm stunned that there is a Java dependency locked at 8? I wonder if @alandipert upgrade of JRuby comment would fix this.

I've sent in #329 that should allow our beloved s3_website on recent versions of Java. I would love a review!
