Description

When running a JUnit test with Testcontainers in Eclipse (2019-03) on macOS (10.14.4), I noticed that there is an error output in the console even though the test passes.

Cannot run program "docker-credential-osxkeychain": error=2, No such file or directory

This error occurs because docker-credential-osxkeychain is in /usr/local/bin which is not included in the PATH Eclipse sees.
Given that the test passes, it may be better to avoid the error or suppress the console output.

A workaround

There might be more proper way, but the easiest workaround would be to launch Eclipse from command line.

# verify /usr/local/bin is included in the PATH
$ echo $PATH
/usr/local/bin:/usr/bin:/usr/sbin:...
# launch eclipse
$ open /Applications/Eclipse.app

Research direction

Start at RegistryAuthLocator.runCredentialProgram and the auth lookup methods named in the stack trace, focusing on behavior when docker-credential-osxkeychain cannot be started. Reproduce the macOS/Eclipse scenario with /usr/local/bin absent from PATH and verify that a passing test no longer emits the unnecessary error output.
