Problem Definition

Assume a project with dependencies in the following directories:

• packages/componentA/dist
• packages/componentB/dist

If we use one cache definition with a wildcard as follows

definitions:
  caches:
    build-cache: packages/**/dist

or

definitions:
  caches:
    build-cache:
      key:
       files:
         - package.json
      path: packages/**/dist

the result is that a directory named ** will be created inside the packages directory, and then one directory named dist will be created inside the directory ** which will contain the files of both packages/componentA/dist and packages/componentB/dist. The directory structure is not preserved in the cache.

Multiple cache definitions can be used, one for each directory. However, if the number of components (and directories to be cached) is large, the yml file will become quite large.

Suggested Solution

When using a wildcard in the cache path, preserve the structure of the directories that are cached.

Workaround

Multiple cache definitions can be used, one for each directory as follows:

definitions:
  caches:
    build-cache:
      key:
       files:
         - package.json
      path: packages/componentA/dist
    build-cache2:
      key:
       files:
         - package.json
      path: packages/componentB/dist
