[BUG] Explicit target for "discovery" not found in the values returned by "--list-targets" flag

Is there an existing issue for this?

Konveyor version

v0.3.0

Priority

Undefined (Default)

Current Behavior

Hi Team,

I am looking to run just "discovery" on the inputs. However, when I check the available targets using the --list-targets option, I don't find the explicit target "discovery," despite it being valid and typically running by default for all targets.
The below are the targets that I see:

Expected Behavior

Returning "discovery" as a valid target in the list of targets will enable to execute just the "discovery" analysis on the input application.

How Reproducible

Always (Default)

Steps To Reproduce

Run the below: .\kantra-latest.exe analyze --list-targets
"discovery" is not listed

Environment

- OS: windows, linux

Anything else?

Additional Analysis:
The --list-targets flag appears to create a new container and walk through all the folders in the rulesets to extract the values of the labels for targets ( values for the key under labels - konveyor.io/target)
In the case of "discovery" and "technology-usage", since there isn't a specific target value assigned, it doesn't show up in the list.

I tested without specifying the --target flag, and it seems to execute on all targets.
However, when explicitly specifying target=discovery (or any string), it functions as expected. This behavior is likely due to the label-selector including the target, so if --target flag is included, it runs all rules under the konveyor.io/include: always label (discovery and technology-usage)

kantra/cmd/analyze.go

Line 895 in 6a5750a

defaultLabels := []string{"discovery"}

Works in the below cases:
./kantra.exe analyze --input testingsample --output report --target discovery --overwrite (This is working because of a bug: #176 )
./kantra.exe analyze --input testingsample --output report --label-selector discovery --overwrite
