no odex

Error message

no odex

What it means

Usage guard in DexWeaverCmd.doCommandLine: no positional odex file argument was given. DexWeaverCmd requires at least one odex input to weave, so running the command with zero remaining args aborts with this HelpException before any work starts.

Solutions

1. Re-run d2j-dex-weaver supplying the required odex file path as a positional argument
2. Run the command with -h/--help to see the full syntax and option list
