Fix IllegalStateException
in Nexus Repository
✅ Solution
IllegalStateException in nexus-repository often arises from attempting to access or modify repository state during an invalid lifecycle phase, such as during component creation or deletion events. To fix it, ensure repository component operations, notably writes and state changes, occur within appropriate event listeners or transactional contexts outside the critical lifecycle stages, potentially leveraging background tasks or explicit database transactions. Review relevant plugins or custom code for synchronous operations during component lifecycle events and defer them where necessary.
