Error message

Error occurred while performing this command, see previous stderr output.

What it means

AbortException thrown by the shared constant CLI_LISTPARAM_SUMMARY_ERROR_TEXT (CLICommand.java:133) after the per-node loop when more than one node was requested and at least one failed. Each per-node failure was already printed to stderr; this is only the summary. It never fires for a single-node invocation because single-node errors propagate directly (hs.size()==1 rethrows).

Solutions

Read the preceding stderr lines: each failing node was printed as `<node>: <message>`.
Remove or fix the failing node and re-run.
Validate the whole list against getComputers() before invoking.

Defensive patterns

Strategy: validation

Validate before calling

Set<String> known = Jenkins.get().getComputers().stream()
    .map(c -> c.getName()).collect(Collectors.toSet());
List<String> valid = nodes.stream().filter(known::contains).toList();

Try / catch

try {
    int rc = cli.execute(args);
} catch (AbortException e) {
    if (CLI_LISTPARAM_SUMMARY_ERROR_TEXT.equals(e.getMessage())) {
        // partial failure: parse prior stderr lines for the failing node
    }
}

Prevention

Pre-filter multi-target lists against getComputers().
Capture and inspect stderr per-target before treating the summary as fatal.

When it happens

Trigger: `offline-node a b c` where at least one of a/b/c does not exist or its cliOffline(cause) throws.

Common situations: Batch scripts that fan out offline-node over a node list containing stale or transient agents.
