:beam-test-tools project fails to build locally

Running the release-verification build (global build of everything) in turn triggers the build of the `beam-test-tools` project, which has some test infrastructure scripts that we run on Jenkins. It seems to work fine on jenkins. However running the build of the project locally fails: https://scans.gradle.com/s/kqhkzyozbpiua/console-log#L6

What seems to happen is the gradle vendoring plugin caches the dependencies locally, but fails to cache simplelru.

One workaround (based on ./gradlew :beam-test-tools:showGopathGoroot)

```

export GOPATH=$PWD/.test-infra/tools/.gogradle/project_gopath
go get github.com/hashicorp/golang-lru/simplelru
./gradlew
:beam-test-tools:build

```

It is able to find the `lrumap` and `simplelru` during the dependency resolution step, and I can see it mentioned in couple of artifacts produced by the `gogradle` plugin. But when it does `:installDepedencies` to actually copy them to `vendor` directory, this specific package is missing. This reproduces for me on a couple of different machines I tried, both on release and master branches
