Description

I wrote a plugin that generates services files for the ServiceLoader
introduced in Java 6 :
http://java.sun.com/javase/6/docs/api/java/util/ServiceLoader.html

for example:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>serviceloader-maven-plugin</artifactId>
<configuration>
<services>
<param>com.foo.Dictionary</param>
<param>com.foo.Operation</param>
</services>
</configuration>
</plugin>
</plugins>
</build>

this will generate these files:
META-INF/services/com.foo.Dictionary
META-INF/services/com.foo.Operation
by scanning the generated classes and finding all
non-abstract/non-interface implementations of the service interfaces.
The plugin itself has no Java 6 dependency

Patch to get the plugin work under Windows as well.

Reamrk: Please excuse me for being quite new to creating patches on the console without having a version controlling system.

Thank you for the plugin.
I have made some corrections to it so it should work under various environments now:
1. Add
@requiresDependencyResolution compile
to get dependencies into the classpath, e.g. for using an interface type from a dependency package
2. Work with regular expressions
3. Use File.separator instead of hardcoded "/"

Hi Andreas, since the plugin is not being picked up maybe we can put it somewhere on github or google code for now? We could then publish it in maven central through the sonatype staging repository...

just a side note:

I believe using annotations and jdk 1.6 annotation processors to generate META-INF services entries is more transparent and deterministic than examining the entire codebase.

I'm not sure if there is a generic purpose annotation processor for this sort of thing, netbeans.org uses it's own version which does some additional stuff on top of the jdk serviceloader.

Sounds like a good idea, maybe we can support both ways of scanning

Hey Francis,
I am quite surprised that you still monitor this issue, nice to see. I appreciate the code being transferred to somewhere else as well as supporting NetBeans loader stuff.

I watch all the issues I create So where do we move the project?

Since I am not very familiar to the various opensource communities out there and further it is your initial contribution, I think it is up to you to decide where to move. Since I am not very familiar with Git, I would prefer Google Code over Github since they offer Subversion. On the other hand I see a chance to get to know Git. What do you prefer?

code uploaded, patch applied but have better way for scanning classes now
works with maven 3

https://github.com/francisdb/serviceloader-maven-plugin

Next step would be to have a look at the netbeans stuff?
