How perform "cloudformation package" command via java sdk?

Question

Here is package command description for cli. Can this command be executed via java sdk?

Answer 1

There is no direct equivalent in the SDKs, it's a CLI feature only. You can invoke it like any OS command, i.e

Runtime.getRuntime().exec(...)

See example in this answer: https://stackoverflow.com/a/3774444/7401700

Use the overloaded form:

public Process exec​(String[] cmdarray,
                    String[] envp,
                    File dir)
             throws IOException
