Best Way To Install Specific Version of SDKMAN

[rgajason]

Hello all,

A recent update to SDKMAN (or one of its dependencies) has broken installs on CentOS 7 due to requirements of newer glibc than is available:

/opt/sdkman/libexec/version: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /opt/sdkman/libexec/version)
/opt/sdkman/libexec/version: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by /opt/sdkman/libexec/version)
/opt/sdkman/libexec/version: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /opt/sdkman/libexec/version)
/opt/sdkman/libexec/version: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by /opt/sdkman/libexec/version)
/opt/sdkman/libexec/version: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by /opt/sdkman/libexec/version)

This is understandable given the age of EL7 and it going out of support next year.

In the interim while my group is moving to a more recent base OS, I'd like to be able to install a specific (read: older) version of SDKMAN.

One idea I had was to patch the installation script and set the version variables specifically:

# Global variables
export SDKMAN_SERVICE="https://api.sdkman.io/2"
export SDKMAN_VERSION="5.16.0"
export SDKMAN_NATIVE_VERSION="0.0.22"

...but I don't know the relationship between SDKMAN_VERSION and SDKMAN_NATIVE_VERSION.

Another option would be to just pull the archive directly from the GH releases, but I don't know how much help the installer is providing that I'd need to re-invent.

Any hints or advice on how to move forward?

Maybe it makes sense to check for GLIBC versions when installing the native components. I think for now what you can do, is delete the contents of the ~/.sdkman/libexec folder, and each command will fallback to their bash version.

I'd also suggest posting these sort of questions in our Slack channel, as mentioned in our contributing guide

Maybe for the time being we could add a flag for enforcing the shell versions of the subcommands.

Thanks for the reply and information. Emptying out the files in the libexec folder did, indeed, allow the code to continue to work on EL7 (well, at least it let me install and run sdk version).
