@hyangah can you give this a look? It has a real "this could be a lot of things" look to it.

had the same issue for me the environment variable in PATH => C:\Program Files\OpenJDK\jdk-19.0.2\bin was missing.

  • make sure to run gomobile init again

When encountering the same problem, gomobile init does not solve the problem.

finally solved by upgrade golang.org/x/mobile to latest version.
go get -u golang.org/x/mobile

After doing a git bisect, this seems to happen when using go 1.20 with a version of gomobile that's missing golang/mobile@406ed3a. Relevant bug report: #56292.

(For folks who are using the gomobile version distributed in the Fedora repositories, I created a bug report to get that updated at: https://bugzilla.redhat.com/show_bug.cgi?id=2209147)

icymi: gomobile works on go1.21 just fine.
