             Summary: :sdks:go:goTest gradle target flakes when run in parallel with other build targets
                 Key: BEAM-11918
                 URL: https://issues.apache.org/jira/browse/BEAM-11918
             Project: Beam
          Issue Type: Bug
          Components: sdk-go
            Reporter: Daniel Oliveira


Running the gradle command :sdks:go:goTest simultaneously with some other commands causes it to sometimes fail with the following error. This appears to be some race condition, most likely related to vendoring, and probably due to building some of the Go SDK gradle submodules (like :sdks:go:test and :sdks:go:examples).

For further reference, the Go Precommit gradle task that causes this looks as follows:

{code}
task("goPreCommit") {
  dependsOn(":sdks:go:goBuild")
  dependsOn(":sdks:go:goTest")

  dependsOn(":sdks:go:examples:goBuild")
  dependsOn(":sdks:go:test:goBuild")

  // Ensure all container Go boot code builds as well.
  dependsOn(":sdks:java:container:goBuild")
  dependsOn(":sdks:python:container:goBuild")
  dependsOn(":sdks:go:container:goBuild")
}
{code}

This can be circumvented by executing the goTest command separately from the building so they don't get executed in parallel, but since the root cause wasn't diagnosed, similar issues might continue to pop up.
