Hi @ggeoffroy68,
I checked SonarQube native rules. I found rule with id java:S1214 which deals with the same subject.

Does a documention or tests exist to prove the rightness of your rule ?

please correct conflicts.

to discuss in core-team :

• no scientific paper to prove this rule
• no argument to prove it's a "green" rule
• there is already a native Sonarqube rule to deal with this rule approximatively ("java:S1214")

for me, rule not acceptable like that.
do we refuse this rule ?

Hello,

difficult for me to validate a rule like this without a minimum of justification. This requires at least some benchmark. May be we should keep it in mind for the future hackathon since I think it is quite easy to perform measures on a rule like this if we have the tools.

Hi @ggeoffroy68,

sorry but with implementation is that situation, we can't accept this implementation because :

• no scientific paper to prove this rule
• no measures to prove it's a "green" rule
• there is already a native Sonarqube rule to deal with this rule approximatively ("java:S1214")

We keep this proposition to measure it when we will have a tool to measure it.
