I dont know where to run the command also

java_dev_appserver --port=8888 --address=0.0.0.0 appengine/build/war/

Hello @XPF_Support

You will need to check that no other program is using port :8888 and that there's no other Appinventor instance making use of the port.
One way to find out processes using the port and killing them is the following:
1- Run netstat -ano | grep ":8888" in a gitbash terminal

You should be listed a process and its PID ( the last one at right )
2- Using the PID you get earlier, run tskill PID to trrminate the process.

Check path for Google Cloud SDK

Horizon · March 19, 2022, 7:03am

You have to use this command in git bash

java_dev_appserver.sh --port=8888 --address=0.0.0.0 appengine/build/war

Aarush_Kumar · March 19, 2022, 7:39am

when using java_dev_appserver cmd in git bash dont forget to add .sh or .cmd which will make the cmd java_dev_appserver.sh --port=8888 --address=0.0.0.0 appengine/build/war

abhi0 · March 19, 2022, 7:43am

Aarush_Kumar · March 19, 2022, 8:02am

abhi0 · March 19, 2022, 8:03am

Aarush_Kumar · March 19, 2022, 8:06am

abhi0 · March 19, 2022, 8:16am

Aarush_Kumar · March 19, 2022, 8:18am

instead of .sh try .cmd

abhi0 · March 19, 2022, 8:38am

Thanks it was successfully installed tell me onething whenever I run this again do I have to go through all process again or is there any command which start the project in future

Aarush_Kumar · March 19, 2022, 8:40am

umm if you edit any thing in code just run ant and if you wanna start appinventor just run the cmd else if you have setup everything you dont need to do anything else.
