Using Gradle 4.8[.1] leads to errors

[sormuras]

Using Gradle 4.8[.1] produces value: strings

See this log excerpt:

Using Gradle 4.7 works

After downgrading to Gradle 4.7, everything works as expected.

Potential underlying reason

@marcphilipp pointed out that there was change in internal AbstractProvider class:

https://github.com/gradle/gradle/blob/v4.8.1/subprojects/core/src/main/java/org/gradle/api/internal/provider/AbstractProvider.java#L57

Related commit: gradle/gradle@5884d64#diff-21e080372a1e92287c45bfa78b444a16

Does Shipkit use this internal type? Or MavenProjectIdentity?

Thank you for reporting this one.
We are using gradle bintray plugin for publishing and it looks like the problem should already be fixed in a new version of the bintray plugin, see bintray/gradle-bintray-plugin#234.
I will adjust our plugin and provide a pr.
