No odex

Error message

No odex

What it means

Usage guard in GenerateCompileStubFromOdex.doCommandLine: no positional odex file was provided. The command's syntax is '[options] <odex0> [odex1 ... odexN]', so with an empty remainingArgs list it aborts with this HelpException and prints help.

Solutions

1. Re-run d2j-generate-stub-from-odex with at least one .odex file path as a positional argument
2. Use -h to review the accepted options (e.g. -o for the output jar) and the expected file format
