I'm trying to use the Cache task inside the AzureDevops release pipeline but I'm getting the following error: "Unable to find pipeline caching scopes."

And my configuration is:

Oh, the variables are created and this task is before the task that I execute the Maven: Cache Task order

So, anybody got an idea of where I'm missing?

Answer 1

I know applying this Cache step before your Maven execution is very convenient for pipeline, such as reducing the whole execution time. Just, unfortunately, until now, we haven't provide this Cache task supported in Release pipeline:

Pipeline caching

Work around:

As I mentioned above, Cache task is very convenient because it can help reduce the time waste in file caching.

So, suggest you apply your release pipeline into Multi-stage YAML format. Though it is running a release phase, but its compile logic is following build.

Check this doc to convert your pipeline: YAML schema.
