关于Elastic Beanstalk EC2实例中Java SE示例JAR包部署目录的咨询

Hey there! I totally get the confusion when switching from manual EC2 management to Elastic Beanstalk—those automated deployments tuck things away in specific spots you might not expect at first. Let’s walk through exactly where your sample JAR is located:

Primary Deployment Directory #

The most common place you’ll find your currently running Java SE application JAR is in:

/var/app/current/

This directory holds the active version of your app that Elastic Beanstalk is running. Just SSH into your EC2 instance and run ls /var/app/current/—you should see your sample JAR file listed here.

Staging & Previous Versions #

If you’ve deployed multiple versions or want to check the staging area before deployment completes, you can look in:

/var/app/staging/

Elastic Beanstalk uses this directory to prepare new deployments before swapping them into the current directory. Older deployed versions might also be stored in timestamped subdirectories under /var/app/versions/, though this can vary slightly based on platform updates.

Quick Way to Verify the Running JAR #

If you want to confirm exactly which JAR is currently being executed by the Java process, run this command:

ps aux | grep java

Look for the -jar flag in the output—it’ll show you the full path to the running JAR file directly.

Hope that helps you track down your sample app! It takes a minute to get used to Elastic Beanstalk’s standardized directory structure, but once you know these spots, it’s smooth sailing.
