helmUpdate*Dependecies fails with "Error: no cached repository for helm-manager"

[rnett]

Gradle: 7.2
Plugin version: 1.6.1
Helm version: 3.7.0

I'm trying to package a basic chart that depends on bitnami postgresql 10.13.1, this seems to cause the plugin to fail.
Stacktrace:

helm update dependencies and helm package . in the source folder works fine.

Looks like it was caused by not explicitly specifying:

repositories {
    bitnami()
}

Not sure if that's intended or not.

Yes, that's intended -- the plugin won't register any repositories by default so you'll have to add them in your build script.

By default the Helm plugin passes a different cache and config path to helm, in order to keep the Gradle builds as independent as possible from the state of a local Helm installation. That's why calling helm in your source folder works in this case: most likely you had the repository already registered with helm repo add.

You can change this behavior so that Gradle would use the same paths as your local Helm installation by setting the Gradle properties helm.xdgDataHome, helm.xdgCacheHome and helm.xdgConfigHome (best put into ~/.gradle/gradle.properties and not in your project because they're somewhat specific to your local environment).
