Nx should not write any messages to stdout when it retries writing the project graph

[dextersealy]

I have a project that's using lerna la --graph to generate the project graph, which uses nx internally. The code runs simultaneously in multiple processes and sometimes two processes will attempt to write the project graph cache at exactly the same time.

When this happens, nx retries up to five times and eventually succeeds. But it writes a message to stdout that interferes with the output from lerna la --graph. See

nx/packages/nx/src/project-graph/nx-deps-cache.ts

Line 152 in 86da1b5

if (err instanceof Error) {

Nx should not write anything to stdout when the operation succeeds. Or, it should use console.error instead of console.log so the message is written to stderr instead of stdout.
