Hi Tim, Thank you so much for the pointers on using Git. When I use git diff command, it states that my local branch is fully merged to version DSpace-6.3. I also did a search on the occurrences of dspace-6.1 if there are pom files that are referencing it but there is none. So I deleted all the JARs in the [dspace and dspace-source]/lib and webapps directory and rerun mvn -U clean package. Now when I run oai import, I did not encounter the java.lang.NoSuchMethodError anymore although I encountered a new error which might be a bug. Anyways, I already filed a JIRA issue about the error (DS-4363 <https://jira.duraspace.org/browse/DS-4363>). In case others encountered the same error, I resolved it by clearing first the 'READ' action of the item policies for the group Anonymous in the owning collection and then adding the 'READ' action again. I used the wildcard policy admin tool for this. Fortunately for me, if you add verbose during OAI import, it is indexing sequentially based on the handle number. In my case, I just visit the next handle to check what collection that item belongs.
[image: NPE-harvest.png] Based on the screenshot above, I just visited the next handle which is 2332 to check which collection it belonged to and then using the wildcard admin policy tool, I reset its policies using the steps I mentioned. It might not be ideal if you have tens of thousands of items. Anyways, after resetting the item policies of every problematic items, I successfully imported all my items in the OAI index. Many thanks again Tim and hope this would help others who might encounter this issue. euler On Saturday, October 12, 2019 at 1:12:06 AM UTC+8, Tim Donohue wrote: > > Hi Euler, > > Unfortunately, Git questions are extremely difficult to give accurate > answers on, as how you are using Git can differ (there are many different > strategies that different institutions use based on their one > preference/needs). > > Just *one* strategy (that I've seen used) is to create your own custom > branch for your site and merge in new versions of the DSpace code when > doing an upgrade.
