Build the Repositories manifest entry from the pom

If you have repositories declared in your pom.xml then these will be added to the capsule manifest (for empty and thin type capsules only obv).

for example:

<repositories>
  <repository>
    <id>central</id>
    <url>http://repo.maven.apache.org/maven2</url>
  </repository>
  <repository>
    <id>local</id>
    <url>file://~/.m2</url>
  </repository>
</repositories>

By default, if you do not have any repositories named then only central will be added. Note the local repo will not be added to capsule by default! So if you are running the empty type and your app is only installed in the local repo then you will need to declare the local repo in your <repositories> tag as above (Obvious use case is when developing your app).

This does away with needing to add the manifest entry Repositories in the plugin configuration. For example:

<manifest>
  <property>
    <name>Repositories</name>
    <value>local central</value>
  </property>
</manifest>

Note that you still can declare them this way but it will override the pom's <repositories> declaration.

Neat! It seems like it picks up the repositories. However, it looks like there is a problem accessing them...

Any ideas?

this is with

        <!-- Specify a custom capsule version -->
        <capsule.version>0.8.0-SNAPSHOT</capsule.version>
        <capsule.maven.plugin.version>0.8.0-SNAPSHOT</capsule.maven.plugin.version>
commented

I noticed you give the videoplaza.org the id central too. I would recommend you name the id of this to something like videoplaza-central so as not to confuse things. (Don't think this makes a difference in this case).

It can't get access to the videoplaza repo, I'm assuming this requires authentication? Not sure if @pron has finished supporting authentication from settings.xml. So perhaps this is the issue.

commented

hmm good catch, i changed that but it did not help. Actually, upon some digging i found that the repository is not authenticated when downloading, sorry about that (I mistook the download and upload repositories).

It seems like no dependancies can be downloaded from the repo specified in the pom; I don't know if the error is from the maven plugin or from capsule itself, but it seems like downloading from a specified repo in the thin jar is not working right... is there a way to view the actual URL requests sent out?

Ok just to confirm, if you remove the vp-central repo and just have maven central repo in the pom like so:

<repositories>
  <repository>
    <id>central</id>
    <url>http://repo.maven.apache.org/maven2</url>
  </repository>
</repositories>

and just have the google guava dependency, it resolves right?

Just want to confirm that its only the vp-central its having trouble accessing. And thus, its likely to be related to authentication.

Woah...

With just central, copypasted like you described:

You need <capsule.version>0.8.0-SNAPSHOT</capsule.version> not 0.7.1.

Aw man!

Updated it and it all works perfectly in the demo repository now! Thanks! :D
