Error while executing Destination connector build with invalid source release


When trying to execute a Destination connector build, an error ‘invalid source release: 21’ is encountered. The build fails during the compileJava task due to deprecated Gradle features.


Hi Team,

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use ‘–warning-mode all’ to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to in the Gradle documentation.
