I get this error when I try to update platform-6.8.3
Could not get resource 'https://cuba-platform.bintray.com/premium/com/haulmont/reports/reports-global/6.8.3/reports-global-6.8.3.pom'.
Solved deleting global .gradle, not project .gradle
We have verified the repositories: all required files are accessible. Did you try to reopen/reassemble the project before deleting .gradle?
Assumably the error occurred due to unstable internet connection.
