[Contributing] Unable to resolve AWS plugins locally

[oharaandrew314]

Hello, I'm trying to make a contribution, but am unable to resolve some of the maven plugins necessary to build the project. In particular:

Cannot resolve plugin software.amazon.awssdk:codegen-lite-maven-plugin:2.24.14-SNAPSHOT

Indeed, the latest version of this plugin available on Maven central is 2.24.11, and there are certainly no snapshots available. This leads me to believe there is some unofficial repository containing the necessary plugins that is not configured in the pom.xml.

If this is true, could someone refer me to the necessary repository URL so I can override the project settings?

Generally speaking, "-SNAPSHOT" is a version that was not released.

If you check the current pom.xml, the is always a SNAPSHOT version, so when you make changes to the SDK locally and build, it'll generate a package with a SNAPSHOT version in your .m2 folder (for maven), like 2.24.14-SNAPSHOT.

Seeing this error during building is weird. What's the command you're running to build the project? Can you share the full error?

Is it a flaky test or is it consistent?

[oharaandrew314]

This test fails consistently for me.

The test may be failing because of the Windows environment. Can you check if running in Linux/MacOS do you also see the issue?
It's ok if you can't, I'm spinning up a Windows instance to try to repro on my side.

Ok, so on a fresh installation of Linux Mint, I ran

$ JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 AWS_REGION=us-east-1 sh mvnw install -Dfindbugs.skip=true -Dcheckstyle.skip=true

and despite several retries, I get one of the following test failures.

[ERROR] Failures: 
[ERROR]   ChannelDiagnosticsTest.stopIdleTimer_previousCallToStartIdleTimer_durationCalculated:37 
Expecting actual:

to be greater than:

I've worked on enough OSS to know it's rare to be able to run a full build on your own machine. But in this case, it's getting in the way of generating the clients. All I want to do is port missing logic from the DynamoDbTable to the DynamoDbAsyncTable. I could have made a bug report, but I figured it would be faster to do it myself. Is there another way for me to get started?

@oharaandrew314 you can go ahead and skip the tests for now. You can also submit the PR, we'll trigger the CodeBuild tests and they'll hopefully catch any problems.

Apologies for the poor experience with the local build.
