AutoValue builder class ${builderTypeDescriptor} did not con

Error message

AutoValue builder class ${builderTypeDescriptor} did not contain a setter for ${autoValueFieldName}

What it means

AutoValueUtils translates getters on an @AutoValue class into setters on its generated Builder to build schemas. getBuilderCreator throws RuntimeException when, for a given AutoValue field name, the builder class exposes no matching setter method — so a Row value cannot be mapped back into the builder.

Solutions

1. Regenerate AutoValue classes with a matching AutoValue version (clean rebuild)
2. Ensure the class is truly annotated with @AutoValue so its generated Builder includes setters for all fields
3. Check for stale/shaded artifacts where the builder and value class come from different builds
4. Compare the AutoValue class getters with the builder setter names to spot mismatches

Example fix

// before
// @AutoValue class has field 'userId' but builder was built from stale generated code without setUserId
// after
mvn clean compile  # regenerate AutoValue builder with setUserId for field userId

for (String getter : autoValueFieldNames) {
  if (!builderSetterNames.contains(getter))
    throw new IllegalStateException("Builder missing setter for " + getter);
}

try { Row[] rows = AutoValueUtils.getRowsFromAutoValue(...); }
catch (RuntimeException e) { if (e.getMessage().contains("did not contain a setter")) { /* rebuild/regenerate */ } else throw e; }

When it happens

Trigger: getBuilderCreator iterates the AutoValue class getters, looks each field up in the builder's setterTypes map, and finds null because the generated builder lacks a setter with that name.

Common situations: Mismatched/incompatible AutoValue versions where builder method naming differs; hand-written or partial builder-like classes; the builder class is stale relative to the annotated class after adding a field without regenerating.
