isis - 如何解决 apache isis 中的这个规范加载器错误

Question

我正在使用收入平台作为测试平台。我在单独的模块 Provider 中添加了一个实体。Provider 通过父属性引用了自身。我想确保在填写父字段时可以使用自动完成功能或能够从列表中选择提供者。每当我在 @DomainObject 注释中添加自动完成选项并引用 ProviderRepository 时，我都会收到如下构建错误。

    [DEBUG] Meta model invalid

}

这是 ProviderRepository

@DomainService(
        nature = NatureOfService.DOMAIN,
        repositoryFor = Provider.class
)
public class ProviderRepository {

    public List<Provider> listAll() {
        return repositoryService.allInstances(Provider.class);
    }

    public List<Provider> findByName(final String name) {
        return repositoryService.allMatches(
                new QueryDefault<>(
                        Provider.class,
                        "findByName",
                        "name", name));
    }

    public Provider create(final String name) {
        final Provider object = new Provider(name);
        serviceRegistry.injectServicesInto(object);
        repositoryService.persist(object);
        return object;
    }
    //region > autoComplete (programmatic)
    @Programmatic // doesn't need to be part of metamodel
    public List<Provider> autoComplete(final String description) {
        return findByName(description);
    }
    //endregion
    @javax.inject.Inject
    RepositoryService repositoryService;
    @javax.inject.Inject
    ServiceRegistry2 serviceRegistry;
    }

我一直无法弄清楚问题是什么。

这里发生的事情是您正在运行 Isis Maven 插件，并且它使用了一个 AppManifest（在 pom.xml 中定义）——我猜它——没有引用包含这些类的新模块。

我猜你可能为你的新模块克隆了模块简单。在这种情况下，您可以通过以下任一方式解决问题：

将新模块添加到新模块中插件引用的清单中（不是模块简单的）
在 mvn 命令行上使用 -Dskip.isis-validate
通过删除 mavenmixin-isis-validate来删除插件
