Hi,
I am getting some "BUILD FAILED" message when trying to build the App Inventor, on a Windows 10 machine, using "Git Bash", according to steps in the readme file (https://github.com/mit-cml/appinventor-sources/blob/master/README.md)
I am using Java\jdk1.8.0_241 and apache-ant-1.10.9, and I was able to build App Inventor of the same computer few years back, so I don't know what might be the issue.
here is the log of the FAIL:
