I am consistently getting a strange error in `publishing` block when using properties in `repositories` block.

The details are available here: [Configure publishing multiple times](https://discuss.gradle.org/t/configure-publishing-multiple-times/9755/7?u=sohrab_hosseini)

I am not even entirely sure why this is happening but the behaviour seems like a bug (unless I have made an obvious mistake somewhere).

This is actually due to the use of `project.properties`. This causes all the project’s properties to be evaluated, including all extensions, such as the the publishing extension. Because the extension is a deferred configurable, once it has been evaluated, future attempts to mutate it will fail. Instead you should use the `Project.property()` method.

```
url "${project.property('mavenRepoUrl')}/repo"
```

You know what, Mark, that actually make sense. I made that change and now it is all working. Cheers.

Would project.mavenRepoUrl work as well ?

That should also work.
