我正在尝试将一些数据流写入Google云存储文件系统中的文件，如下所示（使用Flink 1.8和Scala 2.11）：
data.addSink(new BucketingSink[(String, Int)]("gs://url-try/try.txt"))
但我面临以下错误：

我已经看到了几个关于这个的问题，我也做了：env变量： - FLINK_CONF_DIR
file flink-conf.yaml： - fs.hdfs.hadoopconf：src / main / resources / core-site.xml
核心-site.xml中：
> <property>
> <name>fs.gs.impl</name>
> <value>com.google.cloud.hadoop.fs.gcs.
> GoogleHadoopFileSystem</value>
> <description>The FileSystem for gs: (GCS) uris.</description>
> </property>
> <property>
> <name>fs.AbstractFileSystem.gs.impl</name>
> <value>com.google.cloud.hadoop.fs.gcs.GoogleHadoopFS</value>
> <description>The AbstractFileSystem for gs: (GCS)
> uris.</description>
这些是我的pom依赖：
