Hello, I’m trying to create an extension according to the guide here:
I did everything, everything is good, in java code I entered the code that is in the tutorial, and it does not work! I put everything in the path they wrote, and I run the command: ant extensions on the appinventor folder. This shows me the error:
Build failed```
And in the tutorial it is not written to create the file: build.xml!You may want to send the whole error log instead if just Build Failed, otherwise nothing can be diagnosed from this.
you should try using rush
I fail if rush, I installed, and that I run it I get an error that does not exist!

are you doing this on phone using termux shell ?? Because the root directory is /storage/emulated/0/
I don’t think 
MIT app inventor sources can compile extension using termux
Yes
, I’m on vacation, I’m not home and I do not have the computer next to me, so I tried over the phone …
I thought it would work, because I installed everything properly …
Thanks, I’ll check out the extension builder you brought.
I did not understand how to use the extensions you brought that worked, how to open a project, and how to enter Java code.
You have create Java code and then upload java file there. After few minutes you will get aix file.
By using proot (which could easily be done with a script by AnLiunux), it is possible to install jdk8 and apache-ant. I have built an extension successfully with the original appinventor-sources, but no luck with rush-cli.
Anyway, in my opinion, the most convenient way is what @vknow360 suggested, if you trust the website well enough.
Can you get me a Java code of an extension that will work? I tried a certain code and it did not work for me. I’d be happy if you bring me a code to check.
I would be happy if you bring me a short guide on how to do this, I also could not install a rush …
In the same page they have given link for collintree code, copy and paste into onecompiler.com , download it as java and upload into this site and click submit, you will see the aix
I did not understand, I write the code on the site you brought? what am I doing?
I went to the site you brought, downloaded the code that is there as Java, uploaded to the site of the extensions, sent and received the error:
Error: Config does not contain a field package failed auto detecting package info
