Save 400$ and run/debug local App Engine w/ IntelliJ Community
If you read the official docs from cloud.google.com about how you can run and debug an App Engine Standard Application Locally you got…
… so I must to pay 400$/year to run/debug locally!?
No way sir!
You can debug a local Maven App Engine Standard Application with one click treating it as a remote Java application.
1. Create a run configuration for starting the local development server
It’s mandatory use the appengine:devserver_start goal because it is non blocking, as stated
apply and close.
2. Add JVM remote debug flags to pom.xml
Thanks to Stack Overflow
I have set up my pom.xml like so, and it appears to be working for the most part, I can start the devserver and update…stackoverflow.com
you need to add
to your pom.xml inside the configuration section of the appengine-maven-plugin
as you can see the port used is the 5005, you can use any port you prefer, I leave the default one.
3. Create a remote debug configuration
Apply and don’t close the window ;)
4. Chain both configurations
Here come your one click savings!
In the bottom part of the remote configuration you can add a run/debug configuration that will be execute before!
Now apply and close.
5. Debug the remote configuration
As you will see this run first the Maven goal appengine:devserver_start and when the process is detached it run the remote debug configuration.
So in the IntelliJ “Run” console you have the devserver_start logs and in the “Debug” console you have awesome Java debug tools.
