nx-target-deps

Sample repository to show Nx missing local cache when it shouldn't.

structure

There are two projects:

• one
• two

Via implicit dependencies in nx.json, project "two" depends on project "one".

Project "one" has a build target. This target has "forwardAllArgs" set to false.

Project "two" has a deploy target. This target has "forwardAllArgs" set to true.

Per nx.json, build is a cacheable operation.

instructions

1. npm i
2. nx run one:build
3. nx run two:deploy

Observe a cache hit on one:build.

1. nx run two:deploy --someArg=true

Observe a cache miss on one:build.

1. nx run two:deploy --someArg=false

Observe a cache miss on one:build.

1. nx run two:deploy --someArg=true

Observe a cache hit on one:build.

1. nx run two:deploy --someArg=false

Observe a cache hit on one:build.

expected

Because the build target in project "one" doesn't forward arguments, there should be a cache hit regardless of the arguments passed to the deploy target.

actual

There is a cache miss if arguments differ from the original run.

summary

Missing the cache when different arguments are encountered generally makes sense. But in this case, since arguments are not forwarded, the arguments are effectively the same as those of the results in the cache. Therefore, there should be a cache hit.
