我认为我在文档上非常紧张，但我仍遇到这种异常。 （唯一不同的是，我从Eclipse J2EE运行它，但我不会期望这真的是maters，不是吗？）Apache Beam异常运行wordcount示例
代码:(我没有写这个，它是从梁项目的例子）。我想你必须指定一个谷歌云平台项目并提供正确的凭据来访问它。但是，我没有发现这个示例项目中的任何地方。
public static void main(String[] args) {
// Create a PipelineOptions object. This object lets us set various execution
// options for our pipeline, such as the runner you wish to use. This example
// will run with the DirectRunner by default, based on the class path configured
// in its dependencies.
PipelineOptions options = PipelineOptionsFactory.create();
// Create the Pipeline object with the options we defined above.
Pipeline p = Pipeline.create(options);
// Apply the pipeline's transforms.
// Concept #1: Apply a root transform to the pipeline; in this case, TextIO.Read to read a set
// of input text files. TextIO.Read returns a PCollection where each element is one line from
// the input text (a set of Shakespeare's texts).
// This example reads a public data set consisting of the complete works of Shakespeare.
p.apply(TextIO.Read.from("gs://apache-beam-samples/shakespeare/*"))
.....
)
