chore: Add rest of gradle dependencies

[lqiu96]

This is to match:

dependencies {

  annotationProcessor libraries.auto_value

  implementation( libraries.guava,
    libraries.jsr305,
    libraries.javax_annotations,
    libraries.auto_value_annotations)

  compileOnly libraries.error_prone_annotations

  testImplementation(libraries.junit,
    libraries.truth)
}

[lqiu96]

Keeping JSR305 (not sure what this is used for or if still relevant) and ErrorProneAnnotations (We don't seem to be running error_prone?) dependencies in pom.xml as part of the migration.

I don't think it hurts to keep them in case they have a use case that I'm missing.
