BigQuery: How to load library into java code

Question

I am a new dev in Bigquery. I am following tutorial in https://developers.google.com/bigquery/bigquery-api-quickstart with Java code and imported library from https://developers

Answer 1

You need to add the necessary .jar files (separated by :) to your classpath, i.e.

javac -cp path/to/jar1:path/to/jar2 <your_class.java>

java -cp path/to/jar1:path/to/jar2 <your_class>

alternatively you can add the .jar files to the CLASSPATH environment variable, i.e. (in unix systems)

export CLASSPATH=$CLASSPATH:/path/to/some.jar:/path/to/some/other.jar

This can change depending on your environment (i.e. if you are running these in a webapp server)

Answer 2

Are you using Maven and the BigQuery Java Client? It is recommended to use the Java client. If so, you can easily set it up by configuring your pom.xml file:

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-bigquery</artifactId>
  <version>1.111.1</version>
</dependency>

Answer 3

if you are using maven this is done easily with the following 2 dependence (you can changes the version to the latest one)

    <dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-storage</artifactId>
        <version>v1-rev12-1.19.0</version>
    </dependency>

    <dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-bigquery</artifactId>
        <version>v2-rev168-1.19.0</version>
    </dependency>
