AutoFactory adds unwanted AutoValue annotation processors to classpath

[technoir42]

AutoFactory 1.0-beta6 has a compile-scoped dependency on AutoValue 1.5.3:

auto/factory/pom.xml

Lines 74 to 78 in 2a52c55

	<dependency>
	<groupId>com.google.auto.value</groupId>
	<artifactId>auto-value</artifactId>
	<version>1.5.3</version>
	</dependency>

which adds the following annotation processors to classpath:

com.google.auto.value.extension.memoized.MemoizedValidator
com.google.auto.value.processor.AutoAnnotationProcessor
com.google.auto.value.processor.AutoValueBuilderProcessor
com.google.auto.value.processor.AutoValueProcessor

This is problematic for two reasons:

1. AutoValue 1.5.3 doesn't support incap thus incap has to be disabled for the whole Gradle module.
2. Consumers of AutoFactory don't expect any additional APs besides AutoFactory itself.

This is also breaking incremental annotation processing on AutoFactory 1.0-beta7

w: [kapt] Incremental annotation processing requested, but support is disabled because the following processors are not incremental: 
com.google.auto.value.extension.memoized.MemoizedValidator (NON_INCREMENTAL), 
com.google.auto.value.processor.AutoAnnotationProcessor (NON_INCREMENTAL), 
com.google.auto.value.processor.AutoValueBuilderProcessor (NON_INCREMENTAL), 
com.google.auto.value.processor.AutoValueProcessor (NON_INCREMENTAL).

I use this workaround for now:

configurations.all {
    resolutionStrategy {
        force "com.google.auto.value:auto-value-annotations:1.6.6"
        eachDependency { details ->
            if (details.requested.group == "com.google.auto.value" && details.requested.name == "auto-value") {
                details.useTarget "com.google.auto.value:auto-value-annotations:1.6.6"
            }
        }
    }
}
