Where is your git HEAD currently pointed at? We have supported desugarring Java 8 functionality (e.g., InvokeDynamic) to work with Android since January.

The fact that you received the error fatal: not a git repository suggests that you did not clone from GitHub. This is necessary for two reasons: 1) some dependencies are indicated in the .gitmodules file, which doesn't get included when exporting a ZIP file from GitHub, and 2) the build derives its ID based on the git history, which is lost when using the aforementioned export. Try using a git clone of our main repo and then proceed from there.

ok i have deleted that and run the command

git clone https://github.com/mit-cml/appinventor-sources.git

after cloning success

cd appinventor-sources
than
git submodule update --init

and then
./buildtoools
and made auth key success , when i am trying to build appinventor by pressing 3 or ant all the same error throw

please if you provide me steps from start to end that i can follow i will thankful of you

sir please have a look i am trying to install it since two weak

What is the output of ant -diagnostics?

Hello, I was searching for a similar problem in another project and found this post, I made a clone of the inventor app on GitHub, when building with the repository's own GitHub Action (which is disabled for some reason) I have the same problem, However, updating it to use Java 11 works again.

Hello everyone

Do we have updates on this ?
I cloned from the repo just as of today. HEAD at 63e3f29bb5b33ddcbfc4e7b399217644900dacc3
Tried also what @Brenoepics suggested in bumping Java to 11 but it failed in the same step,PlayApp, but with another error. I'll post a shorter version of the stack, given it seems to repeat itself over and over again

If you're using libraries that take advantage of Java 8 functionality (i.e., InvokeDynamic), then you'll actually need to compile App Inventor with Java 11, which will enable the use of d8 and its desugaring features to add support for newer language features.
