如何在Google Cloud数据流管道项目​​pom中使用beam-sdks-java-core-2.2.0.jar？

I recently set up a Google Cloud dataflow pipeline project using Google Java eclipse plugin. And the default SKD version is 2.1.0 in pom.

我最近使用Google Java eclipse插件设置了Google Cloud数据流管道项目​​。默认的SKD版本是pom中的2.1.0。

<dependencies>
<dependency>
  <groupId>com.google.cloud.dataflow</groupId>
  <artifactId>google-cloud-dataflow-java-sdk-all</artifactId>
  <version>2.1.0</version>
</dependency>
... ...

And the code can be deployed, but it has NullPointerException exception when inserting data into big query. And then I found the following article, it said the issue is fixed in version 2.2.0, https://issues.apache.org/jira/browse/BEAM-2834.

代码可以部署，但在将数据插入大查询时会出现NullPointerException异常。然后我发现了以下文章，它说该问题已在2.2.0版本中修复，https：//issues.apache.org/jira/browse/BEAM-2834。

But I have no idea how to do it. I changed the pom version from 2.1.0 to 2.2.0 and all the dependencies are gone and the error is Missing artifact com.google.cloud.dataflow:google-cloud-dataflow-java-sdk-all:jar:2.2.0 and the versions of google-cloud-dataflow-java-sdk-all-2.1.0.jar and beam-sdks-java-core-2.1.0.jar are the same. I cannot only change beam-sdks-java-core-2.1.0.jar version to 2.2.0

但我不知道该怎么做。我将pom版本从2.1.0更改为2.2.0并且所有依赖项都消失了，错误是Missing artifact com.google.cloud.dataflow：google-cloud-dataflow-java-sdk-all：jar：2.2.0 google-cloud-dataflow-java-sdk-all-2.1.0.jar和beam-sdks-java-core-2.1.0.jar的版本是相同的。我不仅可以将beam-sdks-java-core-2.1.0.jar版本更改为2.2.0

If anybody can show me an example about how to update the jar version or how to fix the NullPointerException exception, that will be a great help for me.

如果有人可以向我展示如何更新jar版本或如何修复NullPointerException异常的例子，那对我来说将是一个很大的帮助。

Thanks a lot in advance.

非常感谢提前。

2.2.0 is not yet available from Maven i.e. Google haven't cut from head/master and made a the new 2.2.0 build. AFAIK, it's currently in progress.

目前尚无法从Maven获得2.2.0，即谷歌没有从主/主人那里切入，并制作了新的2.2.0版本。 AFAIK，它目前正在进行中。

https://github.com/GoogleCloudPlatform/DataflowJavaSDK/releases https://mvnrepository.com/artifact/com.google.cloud.dataflow/google-cloud-dataflow-java-sdk-all

https://github.com/GoogleCloudPlatform/DataflowJavaSDK/releases https://mvnrepository.com/artifact/com.google.cloud.dataflow/google-cloud-dataflow-java-sdk-all

If you want, you could download the latest version and build/use it yourself - if you can't wait for the 2.2.0 version.

如果您愿意，可以下载最新版本并自行构建/使用 - 如果您不能等待2.2.0版本。
