How to use beam-sdks-java-core-2.2.0.jar in Google Cloud dataflow pipeline project pom? - maven

Question

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.
<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.
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
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.
Thanks a lot in advance.

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.
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.
