I got

but change to . the job succeed.

      - aws-ecr/build_and_push_image:

          attach-workspace: true
          workspace-root: .

Expected behavior

If it is equivalent to

    working_directory: /tmp/java-build
    steps:
      - checkout
      - attach_workspace:
          at: /tmp/java-build

workspace-root should support arbitrary path rather than just ..

Looks like in your orb definition, you have nowhere to specify working_directory (so it use the default value . and workspace-root has to be ., otherwise it will complain it cannot find the file).

However, I also realized for some images (e.g. circleci/openjdk:11.0-jdk) you cannot setup working_directory to be .. Otherwise it will fail the checkout step with the error

Directory (.) you are trying to checkout to is not empty and not git repository

i think you may be misunderstanding how persist_to_workspace works @ozooxo

https://circleci.com/docs/2.0/configuration-reference/#persist_to_workspace

the root & path parameters tell our system what files you want to save to your workspace. thus, those paths will need to exist.

the error you saw originally is not because of anything in the orb code—it's because you have some kind of path issue & the dockerfile you're trying to build w/ the ecr orb is not at the path where you're telling it to look for it. have you tried rerunning your job with ssh so you can determine where the dockerfile is?

also, i would recommend against setting working_directory to anything in /tmp
