why use the s3 protocol? because then you do need all kind of AWS maven
plugins
i tried that and they are all horrible

if you have a bucket you also have just http access to it.. so i would use
the normal http url to that p2 repo
We have a few of those on s3 and that is working fine

Hi everyone,
To support some builds done on AWS, I tried to set up an S3 bucket to host
a repository that I would like to use within my tycho target (READ, not
WRITE).
Here's an example on how to do things using pure MVN.

We are able to deploy our application to S3. Additionally, when we access
the repository using HTTP, it works fine, but we'd like to avoid a public
access to some of our repositories. So we set-up kuali wagon and got the
[ERROR] Internal error: java.lang.RuntimeException: Invalid repository
URL: s3://com.castortech.repository/zk-8.5.0.tempfix/: unknown protocol: s3
-> [Help 1]

I tried registering Wagon
<build>
<extensions>
<extension>
<groupId>org.kuali.maven.wagons</groupId>
<artifactId>maven-s3-wagon</artifactId>
<version>[S3 Wagon Version]</version>
</extension>
</extensions>
</build>
As per: https://github.com/jcaddel/maven-s3-wagon/wiki/Usage
https://github.com/eclipse/tycho/blob/master/tycho-p2/tycho-p2-facade/src/main/java/org/eclipse/tycho/p2/resolver/P2DependencyResolver.java
The error pops up when we try to generate a URL to then transform it into
a URI. Do you know if there's anything I'm missing or is what I'm doing
simply unsupported?
Regards,
Stephane
