Ubuntu 19.10 - 'an illegal reflective access operation has occurred' #755

Closed pjgoodall closed 4 years ago

pjgoodall commented 4 years ago

Describe the bug the curl script for installing boot - within README.md, followed by boot -u gives a non-trivial warning 

Downloading https://github.com/boot-clj/boot/releases/download/2.7.2/boot.jar...
Running for the first time, BOOT_VERSION not set: updating to latest.
WARNING: An illegal reflective access operation has occurred
WARNING: Please consider reporting this to the maintainers of dynapath.defaults$fn__1516$fn__1517
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

As this is my first use of the boot system, my expectations are not sophisticated. As an -end-user it's beyond my expertise to report an error to the developers of the component mentioned in the warning

To Reproduce

%sudo bash -c "cd /usr/local/bin && curl -fsSLo boot https://github.com/boot-clj/boot-bin/releases/download/latest/boot.sh && chmod 755 boot"

%boot -u

Expected behavior after install boot -u should cause a clean update.

None of the functionality works AFAIK boot -h, boot repl etc

I had the same issue. It's a known BC break in Java 10.

My problem was that I upgraded to Java 11, but there were old .jars sitting around in ~/.boot. The Java upgrade breaks Boot entirely, including its ability to update itself to a version that would work.

Solution: rm -rf ~/.boot and rerun boot.sh.
