We got an issue with Bintray and jcenter : https://markmail.org/message/hal4od7xeoig6xfw
The jcenter aspect is now fixed with OFBIZ-12171 (actually jcenter will allow download until February 1st 2022)
With our need to upload the Gradle Wrapper we have though still an issue with Bintray: https://markmail.org/message/74u6wsldx3ykzqiv
The problem is once we release a package the scripts at https://github.com/apache/ofbiz-framework/tree/trunk/gradle are freezed. So people using these scripts will not be able to download the related Gradle Wrapper versions.
So we need to replace Bintray by another place to upload the different versions of the Gradle Wrapper. All supported OFBiz versions are concerned.
Note: I have already put https://cwiki.apache.org/confluence/display/OFBIZ/Load+new+gradle+wrapper+version+on+bintray in Wiki Attic
