Java 属性[项目]标记为相互矛盾的注释

我的要求是从谷歌云存储中读取csv文件，并将其加载到谷歌数据存储中。下面是代码片段

import com.google.datastore.v1.Entity;

public class PipelineClass {


static class CreateEntitiesFn extends DoFn<String, Entity> {
  /**

    private static final Logger LOG = LoggerFactory.getLogger(PipelineClass.class);
    private static final long serialVersionUID = 1L;
    private final String namespace;
  private final String kind;
  private final Key ancestorKey;

  CreateEntitiesFn(String namespace, String kind) {
      this.namespace = namespace;
      this.kind = kind;


      ancestorKey = makeAncestorKey(namespace, kind);
  }

  Entity makeEntity(String id, String group) {

      Entity.Builder entityBuilder = Entity.newBuilder();
      Key.Builder keyBuilder = makeKey(ancestorKey, kind, 
                                     UUID.randomUUID().toString());

      if (namespace != null) {

keyBuilder.getPartitionIdBuilder().setNamespaceId(namespace);
      }

      entityBuilder.setKey(keyBuilder.build());
      entityBuilder.getMutableProperties().put("id", 
          makeValue(id).build());
      entityBuilder.getMutableProperties().put("group", 
          makeValue(group).build());


      return entityBuilder.build();
  }

      CSVParser parser = new CSVParser();
      String[] parts = parser.parseLine(c.element());
      String id = parts[0];

      c.output(makeEntity(id, group));
  }
}

static Key makeAncestorKey(@Nullable String namespace, String kind) {
  Key.Builder keyBuilder = makeKey(kind, "root");
  if (namespace != null) {
      keyBuilder.getPartitionIdBuilder().setNamespaceId(namespace);
  }
  return keyBuilder.build();
}


public interface Options extends PipelineOptions {
  @Description("Path of the file to read from and store to Cloud Datastore")
  @Default.String("gs://myproject-263315.appspot.com/source/food.csv")
  String getInput();

  void setInput(String value);

  void setNamespace(@Nullable String value);


  @Description("Number of output shards")

  void setNumShards(int value);
}


public static void main(String args[]) {

 // PipelineOptionsFactory.register(Options.class);
  Options options = 
        PipelineOptionsFactory.fromArgs(args).withValidation().as(Options.class);

  Pipeline p = Pipeline.create(options);
  p.apply(TextIO.read().from(options.getInput()))
          .apply(ParDo.of(new 
CreateEntitiesFn(options.getNamespace(), options.getKind())))

.apply(DatastoreIO.v1().write().withProjectId(options.getProject()));

  p.run();

  }
}

我得到了bleow错误

Exception in thread "main" java.lang.IllegalArgumentException: Property [project] is marked with contradictory annotations. Found [[Default.String(value=myproject-263315) on my.dataflow1.PipelineClass$Options#getProject()], [Default.InstanceFactory(value=class org.apache.beam.sdk.extensions.gcp.options.GcpOptions$DefaultProjectFactory) on org.apache.beam.runners.dataflow.options.DataflowPipelineOptions#getProject()], [Default.InstanceFactory(value=class org.apache.beam.sdk.extensions.gcp.options.GcpOptions$DefaultProjectFactory) on org.apache.beam.sdk.extensions.gcp.options.GcpOptions#getProject()]].

有人能帮我纠正一下吗。在这件事上坚持了很长时间。非常感谢您的帮助

谢谢。

选项“项目”是PiplineOptions中的保留选项。“JobName”是另一个。

我发现了这个，可能对你有用。它有一个Java解决方案和一个简单的Python脚本。希望这有帮助！如果保留了该选项，会发生什么情况？无法在

管道选项工厂中设置值

？我试图设置选项

region

（ApacheBeam 2.21.0），但我得到了相同的错误：
