Smithy Codegen: gradlew breaks on Java version 14, resulting in codegen not working.

[alexforsyth]

Issue: Gradle does not work on java 14, resulting in the codegen quitting with an exception and not generating code.

Reproduction:
Using the newest version of Java (14), and gradle 6.5 running

./gradlew :sdk-codegen:build

from the codegen directory in aws-js-sdk-v3 results in error:

"Could not initialize class org.codehaus.groovy.runtime.InvokerHelper"

This issue is also documented with gradle here: gradle/gradle#12599, however the suggested fix if upgrading to 6.3+ does not clear the error. Downgrading to Java 11 fixes the issue.

I had the same issue, I downgraded my Java to version 11 and started to work.

If you are working on an Android Application, Just go to the root folder of your android project, open gradle-wrapper.properties, and then
replace the distributionUrl with the line below

distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip

This thing Worked for my project, Maybe It will help you too.

We've since upgraded to Gradle 7, which seems to have resolved this.
