Connect to Athena using JDBC in a maven project

问题

I'm trying to connect to the Amazon Athena, using jdbc in a maven project, but an exception is being raised. I think that the class is not being found. In Athena's guide it says:

Set the JDBC property, aws_credentials_provider_class, equal to the class name, and include itin your classpath. (1)

Since I'm using eclipse, I thought that the class would be already in the classpath, but apparently not. I tested the code in a simple java project (not maven) and it worked.

AmazonCredentialsProvider.java:

package athena;
import com.amazonaws.auth.AWSCredentials;

public class AmazonCredentials implements AWSCredentials {
    @Override public String getAWSAccessKeyId() { return "..."; }
    @Override public String getAWSSecretKey() { return "..."; }
}

AmazonCredentialsProvider.java:

package athena;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSCredentialsProvider;

public class AmazonCredentialsProvider implements AWSCredentialsProvider {
    @Override public AWSCredentials getCredentials() { return new AmazonCredentials(); }
    @Override public void refresh() {}
}

The code snippet of the connection :

Class.forName("com.amazonaws.athena.jdbc.AthenaDriver");

Properties properties = new Properties();
properties.setProperty("user", user);
properties.setProperty("password", password);

properties.setProperty("aws_credentials_provider_class", "athena.AmazonCredentialsProvider");
Connection connection = DriverManager.getConnection("jdbc:awsathena://athena." + region + ".amazonaws.com:443", properties);

The exception:

java.sql.SQLException: Failed to load AWS credentials provider class: athena.AmazonCredentialsProvider at com.amazonaws.athena.jdbc.AthenaDriverPropertiesFactory.lambda$parseProperties$2(AthenaDriverPropertiesFactory.java:52) at com.amazonaws.athena.jdbc.AthenaDriverPropertiesFactory.setClientConfigProperty(AthenaDriverPropertiesFactory.java:159) at com.amazonaws.athena.jdbc.AthenaDriverPropertiesFactory.parseProperties(AthenaDriverPropertiesFactory.java:40) at com.amazonaws.athena.jdbc.AthenaDriver.connect(AthenaDriver.java:110) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at athena.Athena.(Athena.java:94) at services.GraphService.verify(GraphService.java:194) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.glassfish.jersey.server.model.internal.ResourceMethodInvocationHandlerFactory.lambda$static$0(ResourceMethodInvocationHandlerFactory.java:76) at org.glassfish.jersey.server.model.internal.AbstractJavaResourceMethodDispatcher$1.run(AbstractJavaResourceMethodDispatcher.java:148) at org.glassfish.jersey.server.model.internal.AbstractJavaResourceMethodDispatcher.invoke(AbstractJavaResourceMethodDispatcher.java:191) at org.glassfish.jersey.server.model.internal.JavaResourceMethodDispatcherProvider$VoidOutInvoker.doDispatch(JavaResourceMethodDispatcherProvider.java:183) at org.glassfish.jersey.server.model.internal.AbstractJavaResourceMethodDispatcher.dispatch(AbstractJavaResourceMethodDispatcher.java:103) at org.glassfish.jersey.server.model.ResourceMethodInvoker.invoke(ResourceMethodInvoker.java:493) at org.glassfish.jersey.server.model.ResourceMethodInvoker.lambda$apply$0(ResourceMethodInvoker.java:405) at org.glassfish.jersey.server.ServerRuntime$AsyncResponder$2$1.run(ServerRuntime.java:843) at org.glassfish.jersey.internal.Errors$1.call(Errors.java:272) at org.glassfish.jersey.internal.Errors$1.call(Errors.java:268) at org.glassfish.jersey.internal.Errors.process(Errors.java:316) at org.glassfish.jersey.internal.Errors.process(Errors.java:298) at org.glassfish.jersey.internal.Errors.process(Errors.java:268) at org.glassfish.jersey.process.internal.RequestScope.runInScope(RequestScope.java:289) at org.glassfish.jersey.server.ServerRuntime$AsyncResponder$2.run(ServerRuntime.java:838) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.ClassNotFoundException: athena.AmazonCredentialsProvider at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at com.amazonaws.athena.jdbc.AthenaDriverPropertiesFactory.lambda$parseProperties$2(AthenaDriverPropertiesFactory.java:44) ... 31 more

Does anyone know how to solve it?
