Variable: cider-enable-nrepl-jvmti-agent

cider-enable-nrepl-jvmti-agent is a customizable variable defined in cider-jack-in.el.

Value

nil

Documentation

When t, add -Djdk.attach.allowAttachSelf to the command line arguments.

This is required for nREPL's bundled JVMTI agent to load, which in turn is required for eval interruption (e.g. M-x cider-interrupt (cider-interrupt)) to work reliably on Java 21 and later -- earlier JDKs do not need it. Disabled by default because attaching the agent has a small startup cost and some hardened environments forbid self-attach.

This variable was added, or its default value changed, in cider version 1.15.0.
