eclipse - 在 java 中从 Eclipse 执行 Apache Beam WordCount 示例时，参数不以“--”错误开头

Question

我正在尝试从 Eclipse 执行示例 WordCount(Java 代码)，如 https://cloud.google.com/dataflow/docs/quickstarts/quickstart-java-eclipse#run-the-wordcount-example-pipeline-云端数据流服务

通过 RunConfiguration 执行时，在 Eclipse 控制台中出现以下错误。

Exception in thread "main" java.lang.IllegalArgumentException: Argument '-output=gs://bucket-for-beam/stage-folder/output-file-prefix' does not begin with '--'

我创建了一个存储桶，名为“bucket-for-beam”文件夹，名为“stage-folder”：

-并且--是不同的。您已经在参数选项卡上指定了第一个。它期待第二个。
