If you are facing issues with Github actions cache not working, there are several ways to solve this problem. In this article, we will explore three different solutions to address this issue.
Solution 1: Clear the cache
The first solution is to clear the cache and force Github actions to rebuild it. This can be done by adding a step in your workflow file to delete the cache before running the actions. Here is an example:
name: Build and Test
on:
push:
branches:
- main
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Clear cache
run: |
echo "::set-env name=CACHE_KEY::${{ runner.os }}-${{ github.sha }}"
echo "::set-env name=CACHE_RESTORE::false"
- name: Restore cache
uses: actions/cache@v2
with:
path: |
~/.cache
key: ${{ runner.os }}-${{ github.sha }}
restore-keys: |
${{ runner.os }}-
This solution ensures that the cache is cleared before running the actions, forcing Github to rebuild it from scratch. However, keep in mind that this may increase the overall execution time of your workflow.
Solution 2: Update the cache key
If clearing the cache doesn’t solve the issue, you can try updating the cache key. The cache key is used to identify the cache and determine if it needs to be rebuilt. By changing the cache key, you can force Github actions to create a new cache. Here is an example:
name: Build and Test
on:
push:
branches:
- main
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Update cache key
run: |
echo "::set-env name=CACHE_KEY::${{ runner.os }}-${{ github.sha }}-v2"
echo "::set-env name=CACHE_RESTORE::true"
- name: Restore cache
uses: actions/cache@v2
with:
path: |
~/.cache
key: ${{ runner.os }}-${{ github.sha }}-v2
restore-keys: |
${{ runner.os }}-
By appending “-v2” to the cache key, a new cache will be created, and the old cache will be ignored. This can help resolve any issues with the existing cache.
Solution 3: Use a different cache action
If the previous solutions don’t work, you can try using a different cache action. Github provides multiple cache actions that you can use in your workflow. One popular alternative is the “actions/cache” action. Here is an example:
name: Build and Test
on:
push:
branches:
- main
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Restore cache
uses: actions/cache@v2
with:
path: |
~/.cache
key: ${{ runner.os }}-${{ github.sha }}
restore-keys: |
${{ runner.os }}-
This alternative cache action may have different behavior and could potentially resolve the cache issue you are facing.
After exploring these three solutions, it is difficult to determine which one is better as it depends on the specific scenario and the cause of the cache issue. It is recommended to try each solution and see which one works best for your situation. Additionally, it is always a good practice to consult the Github Actions documentation and community forums for further guidance.
