Configuring your JDBC connection with Apache Maven

Apache Maven is a software project management and comprehension tool. The Amazon SDK for Java supports Apache Maven projects. For more information, see Using the SDK with Apache Maven in the Amazon SDK for Java Developer Guide.

If you use Apache Maven, you can configure and build your projects to use an Amazon Redshift JDBC driver to connect to your Amazon Redshift cluster. To do this, add the JDBC driver as a dependency in your project's pom.xml file. If you use Maven to build your project and want to use a JDBC connection, take the steps in the following section.

Configuring the JDBC driver as a Maven dependency

To configure the JDBC driver as a Maven dependency

  1. Add either the Amazon repository or the Maven Central repository to the repositories section of your pom.xml file.

    Note

    The URL in the following code example returns an error if used in a browser. Use this URL only in the context of a Maven project.

    For an Amazon Maven repository, use the following.

    <repositories>
    <repository>
      <id>redshift</id>
      <url>http://redshift-maven-repository.s3-website-us-east-1.amazonaws.com/release</url>
    </repository>
</repositories>

    To connect using Secure Sockets Layer (SSL), add the following repository to your pom.xml file.

    <repositories>
    <repository>
      <id>redshift</id>
      <url>https://s3.amazonaws.com/redshift-maven-repository/release</url>
    </repository>
</repositories>

    For a Maven Central repository, add the following to your pom.xml file.

    <repositories>
    <repository>
      <id>redshift</id>
      <url>https://repo1.maven.org/maven2</url>
    </repository>
</repositories>

  2. Declare the version of the driver that you want to use in the dependencies section of your pom.xml file.

    Amazon Redshift offers drivers for tools that are compatible with the JDBC 4.2 API. For information about the functionality supported by these drivers, see Download the Amazon Redshift JDBC driver, version 2.1.

    Add a dependency for the driver as shown following.

    Replace driver-version in the following example with your driver version, for example 2.1.0.1.

    For a JDBC 4.2–compatible driver, use the following. 

    <dependency>
   <groupId>com.amazon.redshift</groupId>
   <artifactId>redshift-jdbc42</artifactId>
   <version>driver-version</version>
</dependency>

    The class name for this driver is com.amazon.redshift.Driver.

The Amazon Redshift Maven drivers need the following optional dependencies when you use IAM database authentication. 

<dependency>
      <groupId>com.amazonaws</groupId>
      <artifactId>aws-java-sdk-core</artifactId>
      <version>1.12.23</version>
      <scope>runtime</scope>
      <optional>true</optional>
</dependency>
    <dependency>
      <groupId>com.amazonaws</groupId>
      <artifactId>aws-java-sdk-redshift</artifactId>
      <version>1.12.23</version>
      <scope>runtime</scope>
      <optional>true</optional>
</dependency>
<dependency>
      <groupId>com.amazonaws</groupId>
      <artifactId>aws-java-sdk-sts</artifactId>
      <version>1.12.23</version>
      <scope>runtime</scope>
      <optional>true</optional>
</dependency>

Upgrading the driver to the latest version

To upgrade or change the Amazon Redshift JDBC driver to the latest version, first modify the version section of the dependency to the latest version of the driver. Then clean your project with the Maven Clean Plugin, as shown following. 

mvn clean
