问题
I'm trying to add a proxy to a public repository (specifically camel-extra). However, I get the following error in my Nexus logs:
Cannot fetch remote index for repository camel-extra
and then further down:
The remoteURL we requested does not exists on remote server (remoteUrl="http://camel-extra.googlecode.com/svn/maven2/releases/.index/nexus-maven-repository-index.properties")
I've ensured that 'Download Remote Indexes' is 'True', repaired the index, updated the index, all to no avail. Browsing to the provided URL shows that the artifacts are there.
So if a repository doesn't have this file, is it not proxy-able through Nexus?
TIA, Roy
UPDATE
Thanks for the answers everyone - was able to pull the artifacts without the index. Thanks again!
回答1:
Repositories without indexes published will be still proxy-able thru Nexus (or any other MRM). Index is only a "topping" providing useful extras like searching the whole remote content, etc.
The index does not participate in proxy-ing at all, hence the lack of it on remote does not affect main functionality of Nexus at all: to proxy artifacts from remote repository.
回答2:
From the nexus documentation, it appears that downloading an index is configurable.
The default for new proxy repositories is enabled, but all of the default repositories included in Nexus have this option disabled.
You should disable the Downloading of Remote Index.
回答3:
Yes, it is proxyable. Just try to download an artifact which is hosted in that repository. The indexes only affect searching and the index published in turn by Nexus.
