Hey Gurpreet,
It sounds like this is something that would be far simpler to accomplish in the
Flexible Environment, which allows access to disk, to open processes, network connections, etc. - essentially, rather than the Standard Environment which is only the language runtime, you get a full VM which still scales and deploys like an App Engine application.
You can find guidance in our documentation or ask me any questions you have. At a high level of generality, I'd suggest that you use the
Dockerfile for your
Custom Runtime to install AjaxSwing and SoX, so that they're on the system ready to be used by your application when it runs / compiles.
You can find examples of Flexible Environment apps on our Github page (
here's the flexible environment example apps for the Java runtime), as well.
Here's a Custom Runtime app which runs an nginx server. You can see in the Dockerfile that it
performs system configuration (you can download and install libraries in the Dockerfile instructions which specify how the VM container will be built).
So, let me know if you have any questions, I'll be happy to assist!
Cheers,
Nick
