helmInstall: Cannot set the value of read-only property 'releaseName'

[andysworkshop]

My release name has a hyphen in it so I tried to override it in the DSL:

helm {
  releases {
    myRelease {
      from charts.myRelease
      releaseName = "my-release"
    }
  }
}

This results in the above error about the name being read only. Can I set the release name without having to define a whole new task deriving from HelmInstall? I would like to use the tasks that the plugin kindly generates for me.

Strange, releaseName is a Property<String> so the set accessor for Groovy DSL should be generated by Gradle. I'll investigate!

In the meantime, you could try method syntax:

releaseName "my-release"

or calling .set() on the property explicitly:

releaseName.set "my-release"

It should also be ok to use the hyphenated name for your DSL object (just use quotes), the plugin will automatically convert it to camel case when generating task names.

I had no idea you could just quote hyphenated values in the DSL, this works:

helm {
  releases {
    "my-release" {
      from charts.myRelease
    }
  }
}

I guess I learned something new today! I'm good now, thanks very much for your help and for providing this plugin - easily the best gradle helm plugin there is.

Thanks! Glad to hear the workaround works for you.

I'll leave this open as it's indeed a bug. I did some clever stuff with multiple interface inheritance and Kotlin delegates, which ended up hiding the Gradle-generated members on HelmRelease. This shouldn't be necessary when moving to Gradle-managed types, but I have to check Gradle version compatibility (wouldn't want to require a higher Gradle version for a bugfix just yet).

fixed in 1.2.3 and 1.3.0
