Edit me

detekt supports the option to fail your build if a threshold of code smell issues is met.

For this the following code must be inside the detekt config:

  maxIssues: 10 # break the build if ten weighted issues are found
    complexity: 2 # every rule of the complexity rule set should count as if two issues were found...
    LongParameterList: 1 # ...with the exception of the LongParameterList rule.
    comments: 0 # comment rules are just a nice to know?!

Every rule and rule set can be attached with an integer value which is the weight of the finding. For example: If you have 5 findings of the category complexity, then your failThreshold of 10 is reached as 5 x 2 = 10.

The formula for weights is: RuleID > RuleSetID > 1.
