[BUG] The presence of a source should not be required for a rule to be triggered

[jmle]

Is there an existing issue for this?

• I have searched the existing issues

Konveyor version

0.5.3

Priority

Critical

Current Behavior

Currently, for a rule to be picked up by kantra, is not enough for it to have a target label:

  labels:
  - konveyor.io/target=quarkus

it needs to have at least one source label too:

  labels:
  - konveyor.io/source=java-ee
  - konveyor.io/source=jakarta-ee
  - konveyor.io/target=quarkus

This doesn't make sense, as sources should not be mandatory.

Expected Behavior

A rule with only targets:

  labels:
  - konveyor.io/target=quarkus

should be picked up without the need of having sources.

How Reproducible

Always (Default)

Steps To Reproduce

1. Create a rule without source labels, but with a target label for quarkus
2. Run against an application with --target quarkus
3. See how the rule is not even picked up
