+## cache
+
+A cache action is configured as:
+
+```yaml
+    - uses: actions/cache
+      with:
+        path: |
+          ${{ inputs.cache-path }}
+          ${{ inputs.cache-path-add }}
+        key: ${{ inputs.cache-prefix }}${{ runner.os }}-jdk${{ inputs.java-version }}-${{ inputs.java-distribution }}-maven${{ inputs.maven-version }}-${{ hashFiles('**/pom.xml') }}
+        restore-keys: ${{ inputs.cache-prefix }}${{ runner.os }}-jdk${{ inputs.java-version }}-${{ inputs.java-distribution }}-maven${{ inputs.maven-version }}-
+```
+
+So we can use for action:
+
+| params            | description                                              |

+| cache-prefix      | prefix value for `key` and `restore-keys` cache params   |
