Local cache of node_modules doesn't work with yarn workspaces

[jogold]

See https://stackoverflow.com/questions/55890275/aws-codebuild-does-not-work-with-yarn-workspaces for a description of the problem.

Also getting this error.

error An unexpected error occurred: "EEXIST: file already exists, mkdir ..."

Any update on this?

It does not work for npm either.

I'm also encountering issues when node_modules is retrieved from cache. For me it's happening with S3 cache.

Hi, any update on this?

[jpswade]

@josephvusich this issue does not appear to have been resolved, would you be able to have a look into it?

[jpswade]

I've seen an approach, by setting a cache directory here:

[jpswade]

This seems like another approach, specifying the entire directory should work.

I've not tried it yet.

Unfortunately this doesn't work for me.

[solarmosaic-kflorence]

I have this same issue. I am using LOCAL cache type and LOCAL_CUSTOM_CACHE cache mode with cache paths ["/root/.sbt/", "/root/.m2/", "/root/.ivy2/", "/root/.cache/"] (this is for an SBT project). I can see in my build that it is correctly caching and restoring those folders when the builds run, but the folders are always empty, even when the builds run right after one another.

[pbn4]

So is there a solution to this?

[solarmosaic-kflorence]

The best solution I can think of for now is to copy all of the cache paths (e.g. /root/.cache) into the build cache (which is stored in S3 for example, /root/.cache -> $CODEBUILD_SRC_DIR/.cache), and then when the build starts up copying it back to the expected locations (e.g. /root/.cache). It works but it adds a bit of complexity to each buildspec.

[rdsedmundo]

I was having the exact same issue ("EEXIST: file already exists, mkdir"), I ended up using S3 cache and it worked pretty well. Note: for some reason the first upload to S3 took way (10 minutes) too long, the others went fine.

If you already have your project configured you can edit the cache accessing the Project -> Edit -> Artifacts -> Additional configuration.

My buildspec.yml is as follows:

version: 0.2

phases:
  install:
    runtime-versions:
       nodejs: 14
  build:
    commands:
      - yarn config set cache-folder /root/.yarn-cache
      - yarn install --frozen-lockfile
      - ...other build commands go here

cache:
  paths:
    - '/root/.yarn-cache/**/*'
    - 'node_modules/**/*'
    # This third entry is only if you're using monorepos (under the packages folder)
    # - 'packages/**/node_modules/**/*'

If you use NPM you'd do something similar, with slightly different commands:

version: 0.2

phases:
  install:
    runtime-versions:
       nodejs: 14
  build:
    commands:
      - npm config -g set prefer-offline true
      - npm config -g set cache /root/.npm
      - npm ci
      - ...other build commands go here

cache:
  paths:
    - '/root/.npm-cache/**/*'
    - 'node_modules/**/*'
    # This third entry is only if you're using monorepos (under the packages folder)
    # - 'packages/**/node_modules/**/*'

[acatusse]

GIVEN :

cache:
  paths:
     - /tmp/cached-dir/
     - /tmp/cached-dir/**/*

Buildspec execute this script on CI :

[[ -f /tmp/cached-dir/cached-file ]] || echo 'FILE NOT CACHED YET'
touch /tmp/cached-dir/cached-file # create the file in the cache (should not print line above next build)

THEN on Aws CI:

Run 2 build in a row and got :

2021/09/12 08:34:48 Moving to directory /codebuild/output/src530968031/src
2021/09/12 08:34:48 Symlinking: /tmp/cached-dir /codebuild/local-cache/custom/5ed44f40b68ea51c687c07d4dfdc9f4c800e493dbad13bc37339f9d742085300/tmp/cached-dir

FILE NOT CACHED YET

Conclusion : Local cache does not work or the setup is kept secret so we use S3 bucket and pay. :)
