AutoValue generation broken when used with javax.validation annotations

[jawpio]

Autovalue code with javax.validation is failed to be generated within eclipse.

• not working example

@AutoValue
public abstract class ColumnRestrictionDto {

	@AutoValue.CopyAnnotations(exclude = Valid.class)
	@Valid
	@NotNull
	public abstract ColumnRestrictionsDto getColumn();

	public static Builder builder() {
		return new AutoValue_ColumnRestrictionDto.Builder();
	}

	@AutoValue.Builder
	@JsonPOJOBuilder(withPrefix = "set")
	public abstract static class Builder {

		public abstract Builder setColumn(ColumnRestrictionsDto value);

		public abstract ColumnRestrictionDto build();
	}
}

• working code

@AutoValue
public abstract class ColumnRestrictionDto {

	public abstract ColumnRestrictionsDto getColumn();

	public static Builder builder() {
		return new AutoValue_ColumnRestrictionDto.Builder();
	}

	@AutoValue.Builder
	@JsonPOJOBuilder(withPrefix = "set")
	public abstract static class Builder {

		public abstract Builder setColumn(ColumnRestrictionsDto value);

		public abstract ColumnRestrictionDto build();
	}
}

you can test it with following code - https://github.com/jawpio/eclipse-autovalue-fail

Could be connected with following issue #505 .

Can you confirm that it fails with the latest AutoValue (1.6.2) before we investigate? The build.gradle there says 1.5.1.

@eamonnmcmanus I can confirm. It fails with 1.6.2 and 1.6.1...

[eamonnmcmanus]

I sent a PR to update to the latest version. It works when invoking Gradle directly. What does it do in Eclipse?

[jawpio]

I can confirm, invoking Gradle directly works fine (also with old AutoValue versions).
In Eclipse AutoValue classes are not generated and if you open "Error Log" view you'll see following exception.
eclipse.autovalue.error.txt

[eamonnmcmanus]

Thanks for attaching the Error Log. The exceptions there show that this is a bug in the Eclipse compiler. I would suggest logging a bug there.

FYI, eclipse issue https://bugs.eclipse.org/bugs/show_bug.cgi?id=535066.

[eamonnmcmanus]

Thanks for logging that! Hopefully it will be addressed punctually by the Eclipse team. We've added workarounds to AutoValue for Eclipse bugs before, but I don't see an obvious way we could do it here.
