Lars Corneliussen commented on NPANDAY-470:
-------------------------------------------
Thanks for reporting this issue. Your observation regarding the msbuild plugin
is correct! The java binding is maintained manually. We even plan to
reimplement it in java.
Netplugins were a great idea, but never really worked as expected. If you find
out what's happening, we are happy to apply a contribution.
We are happy to guide you through the code.

> Key: NPANDAY-470
> URL: https://issues.apache.org/jira/browse/NPANDAY-470
> Project: NPanday
> Issue Type: Bug
> Components: Maven Plugins
> Affects Versions: 1.4.1-incubating
> Environment: windows 7 64 bit, maven 2.2.1
> Reporter: sergio rupena
>
> The plugin does work as documented here
> [http://incubator.apache.org/npanday/docs/1.4.0-incubating/plugins/maven-mojo-generator-plugin/usage.html].
> I have a simple netplugin pom with a single c# class that inherits from
> AbstractMojo (see code below). When I run mvn install on my pom the following
> things happen
> * npanday successfully builds a .net plugin
> * npanday automatically generates a javabinding. The java binding is
> unexpected as this time (according to the documentation it first require to
> invoke an additional command).
> * The generated pom-java.xml does not compile for many reasons. First of all
> the syntax of the annotations cannot be parsed and results in a
> parse-exception, secondly (when you fix the syntax by hand), the java file
> will not compile because it imports from wrong packages and inherits from
> wrong types. Third, when you manually fix those issues it will compile,
> albeit the plugin will not run.
> In the npanday source tree there is an example of the msbuild plugin which
> actually works as netplugin. However, If you try to build the pom-java.xml of
> the msbuild plugin, it will fail for the same reasons. Only the provided
> 'javabinding' works as a plugin and it looks like this has been maintained by
> hand and not via the mojo-generator plugin.
