[DannyAhmedApex]

it's working fine on ly local machine but having issue on building a library on jitpack.io

[DecodingSL]

bro,I have the same problem as you, the cause of the problem is to upgrade the Gradle version, AGP JDK. When I try to lower their version to be consistent with the warehouse, the problem disappears.

[DecodingSL]

The AGP version I use is 7.4.1, the Gradle Version is 7.6, and the JDK version is 11. Gradle and AGP may affect him.

[DecodingSL]

I also downgraded an ndk version, my ndk version is now 23.1.7779620, this is also the possible reason

[blluv]

I think it's probably because rust path is registered in the shell settings such as .bashrc, and the build in android studio gives an error.

“./gradlew cargoBuild” in the terminal works fine.

[mthli]

For me, I use rustup script to install rust.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Then add some configs in your local.properties to fix this issue, no matter how high your AGP version is.

# Fix error=2, No such file or directory.
rust.cargoCommand=/Users/matthew/.cargo/bin/cargo
rust.rustcCommand=/Users/matthew/.cargo/bin/rustc

/Users/matthew is my $HOME directory.

# Fix error=2, No such file or directory.
rust.cargoCommand=/Users/matthew/.cargo/bin/cargo
rust.rustcCommand=/Users/matthew/.cargo/bin/rustc

@mthli Thank you so much! This works for me.
