Whether the ToMap converter should be generated.

A statement naming neither a resultRowType nor a resultRowConverter answers with a Map<String, Object> per row, read by a converter generated for the purpose. This decides whether that converter is written.

Turn it off once every statement names a type of its own, and a statement that goes back to answering with maps then fails the build instead of quietly doing so — which is the point of turning it off.

Configuration Options

Option: ’true'

The default. Statements naming no type answer with maps:

package com.example.persistence.converter;

public final class ToMapConverter {

    public Map<String, Object> apply(final ResultSet resultSet) throws SQLException {
        // ... reads every column of the row by its label
    }

}

Option: ‘false’

No converter is written, so a statement that would need one fails the build.

In order to use YoSQL together with Gradle , take a look at the tooling documentation for Gradle . The generateMapConverter setting can be configured using Gradle in Kotlin syntax like this:

plugins {
  java
  id("wtf.metio.yosql") version "2026.8.8"
}

yosql {
  converter {
    generateMapConverter.set(configValue)
  }
}

or in Groovy syntax like this:

}

yosql {
  converter {
    generateMapConverter = configValue
  }
}
