No updates in the user guide should be required for java. It just changes what "app" cdk runs when you invoke a CLI command.

However, it could be made more clear that you don't necessarily need to do compile after every step, since now synth does that automatically if it needs to. This is similar to the way the getting started for .NET cdk.json works.

The new user guide is incorrect about C# though, since the init code and the instructions I wrote for the getting started (which assumes you are creating from scratch) differ. The init template for .NET needs to be updated to match the assumptions in this new doc.

I ran pkglint fix, which changed a lot of files...

How do you want me to handle this?

[eladb]

Would be nice if the getting started guide for java will use the same approach as the new init template. It seems like it still uses the classpath approach

Regarding pkglint : Merge from master you should be fine.

There is no "Getting Started" topic in the CDK User Guide on docs.aws.amazon.com. I replaced it by creating an "Installing and Configuring the AWS CDK" topic, and moved the examples of creating a simple CDK app into the next section, "Tutorial", which only uses cdk init ... to create the initial app. I'll make a run through the Java and DotNet/C# sections with the latest bits to ensure they are correct.
