findProperty() violates isolated project constraints

[solrudev]

When enabling isolated projects option for Gradle, project sync failure contains the following violation:

Project {project_name} cannot dynamically look up a property in the parent project :

Stack trace points to this line.

Possible replacement for findProperty() is providers.gradleProperty().

Unfortunately gradleProperty and findProperty are not the same. gradleProperty will only return properties from the root project, user home or cli, while findProperty also returns properties from the project's gradle.properties. See gradle/gradle#23572 which is effectively a blocker. We rely on being able to read project properties for configuring module specific things like the name or artifact id.

That said some usages can probably be replaced already, so that projects that use the base plugin and don't call pomFromGradleProperties are compatible with isolated projects.
