Drone: fail to work with cache volume "Failed to unmarshal Volumes"

[aisensiy]

Try to use drone with its Volume Cache with the following .drone.yml but get an error:

Failed to unmarshal Volumes

I already add a volume /tmp:/tmp for drone agent but it still doesn't work.

pipeline:
  restore-cache:
    image: drillster/drone-volume-cache
    restore: true
    mount: [ /drone/.gradle, /drone/.m2 ]
    volumes: /tmp/cache:/cache

  build:
    image: java:openjdk-8
    environment:
      - M2_HOME=/drone/.m2
      - MAVEN_HOME=/drone/.m2
      - GRADLE_USER_HOME=/drone/.gradle
    commands:
      - ./gradlew test

  rebuild-cache:
    image: drillster/drone-volume-cache
    rebuild: true
    mount: [ /drone/.gradle, /drone/.m2 ]
    volumes: /tmp/cache:/cache
    when: 
      status: [ success, failure ]

I'm having a similar issue. Were you able to fix your issue? If so, how?

[aisensiy]

I think the issue is that DO NOT cache things out of the current directory. The mount: [ /drone/.gradle, /drone/.m2 ] is out of the current directory. Try use ./.gradle and ./.m2.
