Integration tests mysteriously fail if DynamoDb Local is added as a maven repo

[Ali Akhtar]

Enter code here...

Enter code here...

I'm trying to run integration tests w/ Dropwizard, here's the base class:

public abstract class IntegrationTest
{
    @ClassRule
    public static DropwizardAppRule<MyConfiguration> APP =
            new DropwizardAppRule<>(MyApplication.class, resourceFilePath("test.json"));


    private final Logger log = Logging.get(this);


    protected final Client client = ClientBuilder.newClient();

    private String url(String path)
    {
        return "http://localhost:" + APP.getLocalPort() + path;
    }


    protected Response post(String path, Object entity)
    {
        return client.target(url(path)).request().buildPost(Entity.json(entity)).invoke();
    }


    protected Response get(String path)
    {
        return client.target( url(path) ).request().buildGet().invoke();
    }
}

If I add the following maven dependency:
          

       

        <dependency>
             <groupId>com.amazonaws</groupId>
            <artifactId>DynamoDBLocal</artifactId>
            <version>1.10.5.1</version>
        </dependency>

<repositories>
        <repository>
            <id>dynamodblocal</id>
            <name>AWS DynamoDB Local Release Repository</name>
            <url>http://dynamodb-local.s3-website-us-west-2.amazonaws.com/release</url>
        </repository>
    </repositories>

Then I get the following stack trace when I try to run a test:

}

Everything works if I just take out the dynamodb dependency. Any ideas what's going on?

[Tim Altmann]

DynamoDBLocal has a transitive dependency to org.eclipse.jetty:jetty-server:8.1.12.v20130726

Dropwizard 1.0.0-rc3 requires jetty.version = 9.3.8.v20160314 (dropwizard-bom)

Your classloader is likely pulling in the older version when you include DynamoDBLocal.  You'll probably have to exclude the old version (try: https://maven.apache.org/guides/introduction/introduction-to-optional-and-excludes-dependencies.html) and then test to see if DynamoDBLocal still works with the newer jetty server.

Thanks a bunch.

Tried that, and I'm now getting a different stack trace:

Looking at the dependencies, I can't find any for apache http for DynamoDBLocal, though it does have one for apache commons-lang3 and commons-cli. Any ideas on which other deps I need to exclude?

[Ali Akhtar]

Adding this:

           

<dependency>
                <groupId>org.apache.httpcomponents</groupId>
                <artifactId>httpclient</artifactId>
                <version>4.5.2</version>
            </dependency>

to the dependency management fixed this. Thanks for the pointer along the right direction!
