Executing Gradle builds on TeamCity

[panarik]

You can suggest the relevance of the Gradle flow instructions?
on the site:
https://guides.gradle.org/executing-gradle-builds-on-teamcity/

Setting it up with Gradle in. TeamCity agrees to work only through the wrapper.

"Use gradle wrapper to build a project"

1. Downloaded the test project: software https://github.com/gradle/gradle-site-plugin.git

I run the build from the command line like this:

gradlew build

After the build, an error with an incompatible version appears:
Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.

In this project:
gradle-site-plugin\gradle\wrapper\gradle-wrapper.properties:
https\://services.gradle.org/distributions/gradle-5.4.1-bin.zip

Can be can be without updates version of build as something?
