Making a maven mirror for building aries - properties-maven-plugin refuses
to cooperate
Hi all,
I'm trying to set up a local mirror of the maven repository required by
Aries. The central repository has been a bit too unavailable lately for
production use.
These are the steps I'm following:
1. Build Aries normally.
2. Move my .m2 cache to a new location on my filesystem, ${myrepository}.
3. Configure a new .m2/settings.xml to use the ${myrepository} as a
mirror.
4. Build aries. All dependencies are downloaded normally, until we get to
properties-maven-plugin, and then it dies in a heap:
...
Downloading:
file:///home/cumminsh/.m2good/repository/org/apache/maven/plugins/maven-antrun-plugin/1.2/maven-antrun-plugin-1.2.jar
22K downloaded (maven-antrun-plugin-1.2.jar)
[INFO] artifact org.codehaus.mojo:properties-maven-plugin: checking for
updates from central
[INFO]
------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO]
------------------------------------------------------------------------
[INFO] The plugin 'org.codehaus.mojo:properties-maven-plugin' does not
exist or no valid version could be found
No amount of wiping my local cache fixes it.
A few things are mystifying me. I know the metadata in my local mirror is
good, because it's what just got downloaded from the central repository
into my bundle cache. So why does running against the central repository
pass, but an apparently identical local copy fail? If I download the
properties-maven-plugin jars and metadata manually and drop them into my
local cache, I can build fine, so it's just the download which is causing
issues, not the usage.
The second perplexing thing is that a few months ago, when we were on
0.1-SNAPSHOT, this process worked fine. What's changed between now and
then?
I could try a repository management tool like Nexus, but I can't imagine
they'd produce metadata more valid than the metadata I produce myself by
doing a local build and generating a cache.
I guess this is a more general maven question, or perhaps even a question
for the properties-maven-plugin list, but I know there are a lot of maven
experts among the aries community. Google throws up a more general
codehaus bug http://jira.codehaus.org/browse/MNG-4001, but no suggested
workarounds except for moving to maven 3.
Anyone have any inspiration?
Thanks,
Holly

Thanks everyone for all your suggestions, as a result of which I now have
my build working against a private maven mirror. Archiva was a bit of a
non-starter for me because it won't run with an IBM JVM (a known bug, it
seems). However, the maven-proxy project did the trick. My requirements
are so simple that even the obsolete implementation was good enough. :)
I hit a second problem with the 0.0.313 version of the aQute bndlib plugin
required by pax-swissbox, which was only available from the aQute maven
repository. I'm not sure why this doesn't cause more general problems, but
it was easily solved by adding the aQute repo to my mirror's configuration
file.
Cheers,
Holly

I would suggest trying to specify a local central mirror first -
http://maven.apache.org/guides/mini/guide-mirror-settings.html
http://docs.codehaus.org/display/MAVENUSER/Mirrors+Repositories
If that doesn't work or you need repeatable builds (like for production
usage) then I'd suggest going with Nexus, which is easy to setup as a
caching proxy for all of the repos your builds need.

Hi Holly
I wonder how you config the new settings.xml. Does it contain any
reference to the maven central repo? If not, I think we should not
see a message like "checking for updates from central" as it can be
configured to only to download from your local repo or internal repo.

AFAIK, the only problem with using a local repository as a remote repository is the metadata, so theoretically if you specify plugin versions and don't use version ranges anywhere, it might work. But don't be surprised if it doesn't :)

I don't think mvnproxy is maintained anymore. More modern solutions are Nexus, Archiva, and Artifactory.

Have you looked at mvnproxy

Hi Justin,
Thanks for the speedy reply. I was trying to avoid the overhead of a
repository manager for what's a pretty simple use case (one consuming
product, shared filesystem already available) but I will have a go.
> The contents of local repository cannot be used as a remote
> repository. You should use a repository manager.
That's a good point about the local repository, thanks. What I'd tried
first was manually mirroring the org.codehaus.mojo metadata and archives
down to my private mirror, similarly without success. (The private mirror
worked great for building our aries 0.1 levels, but not for our 0.2
levels.)
As with the local repository-copy, everything worked except up until the
download of the properties-maven-plugin. I'm not convinced even the
repository manager will solve the problem, but I'll try and eliminate my
repository management techniques as a cause of the problem before I
investigate further. :)

The contents of local repository cannot be used as a remote repository. You should use a repository manager.
