ebitenmobile fails in vendor mode and has no option to disable vendor mod

[kordax]

Hi, I have next problem while executing

ebitenmobile bind -a -x -v -target android -javapkg net.isoftservices.client -o ./android/app/libs/client.aar ./src/game/android

Output is:

ebitenmobile bind -a -x -v -target android -javapkg net.isoftservices.client -o ./android/app/libs/client.aar ./src/game/android

The problem is that ebitenmobile doesn't support -mod mod or -mod readonly and therefore it fails on Gobind when vendor dir is present in the root project's structure.
The current Gomobile package doesn't contain bind and cmd packages in vendor mode and I cannot explicitly force vendor mod for bind/cmd packages using _ import.

$ ls -F vendor/golang.org/x/mobile/
app/  asset/  AUTHORS  CONTRIBUTORS  event/  geom/  gl/  internal/  LICENSE  PATENTS

Is it possible to ignore the vendor directory somehow?
It works fine if there's no vendor directory in the project.

This problem is not as easy as it seems to be, because potentially the Gobind itself can be incapable of such an option.

I'm not sure the situation, but is this your vendor directory? Is it possible to include cmd in your vendor?

[kordax]

I can do this, but it will be gone with the next go mod vendor command.

I think this is not an issue in Ebiten but in gomobile. A regular gomobile-bind caused the same error.

Yep, looks like it's gobind issue:

gobind -lang=go,java -outdir=/tmp/gomobile-work-1386653115 -javapkg=net.isoftservices.client ./src/game/android
