Bazel使用针对ser / Deser的Jackson注释构建并生成Java类

Question

So, we have been trying to xploring bazel as a build system for our organization, since we have a huge monorepo. One of the problems I'm facing is, we have some code-gen classes which use Jackson's annotation processors to generate immutable copies of some file types.

Eg :

@JsonSerialze
@JsonInclude(JsonInclude.Include.NON_EMPTY)
@Value.Immutable
@JsonDeserialize(as=ImmutableABC.class)
Public abstract class ABC {
...
}

So, for this , I include a java_plugin tag in bazel build file for this module as follows :

Java_plugin(
        name="abcgen",
        srcs=["src/.../ABC.java"],
        Deps=[ {jackson-deps go here}],
        processor_class = "org.immutables.processor.ProxyProcessor",
)

This always fails , saying cannot find the ImmutableABC.class file which is referenced in the annotation. Any ideas? Am I missing the processor class for the Jackson annotations, and also is it possible to include multiple processor classes?

对于遇到此类问题的任何人，请确保您的插件的generates_api = 1，如果在库中使用了生成的类（对于杰克逊部分而言），那实际上不是问题
