https://openjdk.org/jeps/456 (Java 22) added unnamed variables denoted by _ (underscore)
Rule: FormalParameterNamingConventions
Describe the solution you'd like
FormalParameterNamingConventions should accept _ as a valid name by default. Currently it complains The lambda parameter name '_' doesn't match '[a-z][a-zA-Z0-9]*'.
Describe alternatives you've considered
I'm using the following workaround:
<rule ref="category/java/codestyle.xml/FormalParameterNamingConventions">
<properties>
<property name="methodParameterPattern" value="_|[a-z][a-zA-Z0-9]*"/>
<property name="finalMethodParameterPattern" value="_|[a-z][a-zA-Z0-9]*"/>
<property name="lambdaParameterPattern" value="_|[a-z][a-zA-Z0-9]*"/>
<property name="explicitLambdaParameterPattern" value="_|[a-z][a-zA-Z0-9]*"/>
</properties>
</rule>
