@Mark when I click the "manage" button next to the error for a project
named "Free_hand", I get the below message:
Manage Old Data
When there are changes in how data is stored on disk, Jenkins uses the
following strategy: data is migrated to the new structure when it is
loaded, but items/records are not resaved in the new format. This allows
for downgrading Jenkins if necessary. However, it can also leave data on
disk in the old format indefinitely. The table below lists items/records
containing such data, and the Jenkins version(s) where the data structure
was changed.
Sometimes errors occur while reading data (if a plugin adds some data and
that plugin is later disabled, if migration code is not written for
structure changes, or if Jenkins is downgraded after it has already written
data not readable by the older version). These errors are logged, but the
unreadable data is then skipped over, allowing Jenkins to start up and
function properly.
Type Name Version
No old data was found.
Unreadable Data
It is ok to leave unreadable data in these items/records, as Jenkins will
simply ignore it. To avoid the log messages at Jenkins startup you can
permanently delete the unreadable data by resaving these items/records
using the button below the list.
