Building the Cloud Storage and BigQuery connectors

Note that build requires Java 8 and fails with newer Java versions.

To build the connector for specific Hadoop version, run the following commands from the main directory:

# with Hadoop 2 and YARN support:
./mvnw -P hadoop2 clean package

with Hadoop 3 and YARN support:
./mvnw -P hadoop3 clean package

In order to verify test coverage for specific Hadoop version, run the following commands from the main directory:

# with Hadoop 2 and YARN support:
./mvnw -P hadoop2 -P coverage clean verify

with Hadoop 3 and YARN support:
./mvnw -P hadoop3 -P coverage clean verify

The Cloud Storage connector JAR can be found in

gcs/target/

bigquery/target/

Adding the Cloud Storage and BigQuery connectors to your build

Maven group ID is

com.google.cloud.bigdataoss
