The build scan was not published due to a configuration problem.
The Gradle Terms of Service have not been agreed to.
To agree to the Gradle Terms of Service, include the following in your root project's configuration:
buildScan { termsOfServiceUrl = "https://gradle.com/terms-of-service"; termsOfServiceAgree = "yes" }
For more information, please see https://gradle.com/scans/help/plugin-terms-of-service.
Alternatively, if you are using Gradle Enterprise, specify the server location.

and that didn´t helped me to build jd-core; how can i build it ?

This is not so much a Gradle question and is thus a bit misplaced in this forum.
There are simply 17 of 323 tests failing.
Why they are failing you can see in the test report printed in the output: file:///C:/jd-core%20deocmpiler%20github%20repository%20built%20place/jd-core/build/reports/tests/test/index.html.
But why they are failing or what do do is more a question for the jd-core project, not for the Gradle community.
Actually, for me there is only one failing test.

Why the build scan couldn’t be published is also strange, for me it worked perfectly fine.
After the build finished it asked whether I agree to the ToS and publish the build scan and if I type “yes”, it publishes the scan.
