Unable to debug aws-sam project using aws eclipse toolkit

Question

I am trying to debug aws-sam application using the steps here . However, I am not able to get eclipse toolkit to enter debug mode. The first steps in running in debug mode appear to work ie the project builds and runs tests successfully as can be seen in the output below

The next step after this fails and I am unable to interpret the error message it prints out.

[AWS Toolkit] SAM Local invocation done.

I am not sure what "specified file" it is unable to find as it is not clear from the message above. I have tested my docker installation using the docker run hello-world command and it is working as expected.

What am I missing here in getting the basic example to work? Is this a problem with docker on Windows or a problem with aws eclipse toolkit?

Answer 1

Turns out that the problem described above was due to not running eclipse as an Administrator ie by right-click -> Run as Administrator .

However, now I have run into a different problem described here
