2020-04-08 7:00 AM UTC. Red Hat Jira at issues.redhat.com will be down for 1 hour due to an upgrade. Red Hat Jira is going to update the email address used for notifications to the email associated with your redhat.com user profile. You can review and make changes to your email in the redhat.com user profile if necessary to prevent notification delivery change.
Recent changes (see this commit for MODE-2105 and MODE-2016) corrected the POM file of the repository explorer project to specify the version of the GWT Maven plugin, but it hardcoded the version where it should have used a version property.
