AWS CodeBuild local cache failing to actually cache?

Question

I\'ve been trying to get AWS CodeBuild\'s local cache to work and for the life of me I can\'t get even the most basic cache to work. My ultimate goal is to cache Gradle arti

Answer 1

I have been trying to make the cache work myself with limited success.

Not from any public source, but these are some observations:

• The cache will only be avilable if the build time is more than 5 minutes.

• Cache can be used if the new build is successfully placed on the same build host.

• Cache can be used if the new build is being run within 5-15 minutes of the last build. Cache may stay available based on the last build time with a max of 15 minutes.

• Despite builds exceeding 5 minutes, the cache may not always work probably due to build being placed on different build host.

• Additionally, in the case where the cache speeds up the new build to below 5 minutes, that build will not be cached resulting in subsequent miss.

While I trust CodeBuild engineers had good reasons to design it this way, the above limitations renders this local cache functionality of limited use in my opinion.
