java - 歧管 load().fromJson() 抛出 java.lang.ClassCastException

Question

我遵循了https://github.com/manifold-systems/manifold/tree/master/manifold-deps-parent/manifold-json下的文档并部署了一个 jar，它仅提供 User 类，使用 Maven 编译插件作为记录：

<build>
    <plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.8.1</version>
        <configuration>
        <compilerArgs>
            <!-- Configure manifold plugin-->
            <arg>-Xplugin:Manifold</arg>
            <arg>-Amanifold.source.json=^com\.example\.schemas\.User$</arg>
        </compilerArgs>
        <!-- Add the processor path for the plugin (required for Java 9+) -->
        <annotationProcessorPaths>
            <path>
            <groupId>systems.manifold</groupId>
            <artifactId>manifold-json</artifactId>
            <version>2020.1.44</version>
            </path>
        </annotationProcessorPaths>
        </configuration>

我的另一个项目将此包用作依赖项，并且以下代码可以正常工作：

import com.example.schemas.User;
...

User user = User.builder("Scott McKinney", "[e-mail]")
  .build();

但这会引发异常：

User user = User.load().fromJson("{\"name\": \"Scott McKinney\", \"email\": \"[e-mail]\"}");

java.lang.ClassCastException: class manifold.json.rt.api.DataBindings 
  cannot be cast to class com.example.schemas.User (manifold.json.rt.api.DataBindings 
  and com.example.schemas.User are in unnamed module of loader 'app')
