Support for Java 9's module system

[metacodez]

For a while now I am trying to get my projects' modues straigt as of Java9's module system. As of now just two dependencies left in my projects (https://bitbucket.org/refcodes/) without stable module name, one of them comes from AWS.

An idea to help other Java 9 modules and their module-info.java declaration would be to put an entry into AWS' JAR Manifest-File, such as: Automatic-Module-Name: aws.java.sdk.core to get stable module references. In Maven, this can be achieved by tweaking the maven-jar-plugin similar to:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-jar-plugin</artifactId>
	<configuration>
		<archive>
			...
			<manifestEntries>
				<Automatic-Module-Name>aws.java.sdk.core</Automatic-Module-Name>
			</manifestEntries>
		</archive>
	</configuration>
	...
</plugin>

I would be very greatful when you generate such a Manifest entry as AWS provides great cloud services!

Hi @metacodez thank you for reaching out!

This would be such a big change to be made in SDK v1 that will probably not be considered. I recommend to take a look and eventually migrate to SDK v2, where Automatic-Module-Name is already supported - https://github.com/aws/aws-sdk-java-v2/

Hello @debora-ito thank you for your fast reply. Indeed v2 looks very promising, though I cannot find SimpleDB with an automatic module name, I just found some preview versions which seem to be missing the automatic module names and which did not change their preview status since Jul, 2018:

<!-- https://mvnrepository.com/artifact/software.amazon.awssdk/simpledb -->
<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>simpledb</artifactId>
    <version>2.0.0-preview-11</version>
</dependency>

Are there any chances this artifact gets automatic module names and gets out of preview status or is it contained in some other artifact I was missing?

Thanks beforehand & best regards!

@metacodez I will ask the team behind SimpleDB API as I don't know for sure. Will let you know when they reply back.

Hello @debora-ito thank you & looking forward for their reply!

Hello @debora-ito, I plan to prepare a next release of REFCODES.ORG artefacts, do you have nay news on this preview issue regarding SimpleDb?

<!-- https://mvnrepository.com/artifact/software.amazon.awssdk/simpledb -->
<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>simpledb</artifactId>
    <version>2.0.0-preview-11</version>
</dependency>

Thanks beforehand & best regards -

Good timing! I just got a reply from the Simple DB team, saying they have no plans to make the APIs available in the Java SDK v2, unfortunately.

Marking this issue to auto close soon. Feel free to reopen or add a comment if you have further questions.

Thanks for your investigation!

For me to get it right: When I stay with 2.0.0-preview-11 for SimpleDB I will have Java 9's module support, but no updates or bugfixes, as it will never make it out of preview. When I go back to 1.11.865 I will get updates but I will miss Java 9's module support as it will never come for the 1.xx.yyy versions?

Now I got to decide as I already use S3 with 2.x.y version APIs and have to stay with 1.11.865 for SimpleDB (feels somehow as if I was mixing two version lines of AWS libraries).

Are there any reasons for the SimpleDB API team not to follow up on a final release succeeding version 2.0.0-preview-11? E.g. will SimpleDB be deprecated (or is it already deprecated) and not be supported by AWS at all any more in the near future? Then maybe I should skip support for SimpleDB at all and look for an alternative? Which NoSQL DB in the AWS cloud would be an alternative for SimpleDB?
