[forge-dev] New Plugin: no class org/jboss/forge/project/facets/BaseFacet

[Mario Antollini]

Hello,

I am part of the Switchyard community. We had a set of plugins working for
Forge1.0.0.Alpha4 and we now need to move forward to Forge1.0.0.Beta3.

 In Alpha4 we were installing the plugins just copying the jars in the libs
dir. Now, to test the plugins, we need to instruct forge to install them
itself. When I execute the command "forge source-plugin <puglin_src_dir>"
everything works OK: the plugin gets compiled and installed in my .forge dir
inside my home dir. 

 However, after the installation, when I run forge, it does not start and
throws the following error:

 log4j:ERROR A "org.apache.log4j.xml.DOMConfigurator" object is not
assignable to a "org.apache.log4j.spi.Configurator" variable.

log4j:ERROR The class "org.apache.log4j.spi.Configurator" was loaded by

My plugin depends on forge-shell.jar:

<dependency>

      <groupId>org.jboss.forge</groupId>

      <artifactId>forge-shell</artifactId>

      <version>1.0.0.Beta3</version>

      <scope>provided</scope>

    </dependency>

So, I see the problem is that org/jboss/forge/project/facets/BaseFacet is
not being found during Forge startup. But why is that? I can see
forge-shell-api.jar (the jar containing the required class) is in the
<forge-1.0.0.Beta3>\modules\org\jboss\forge\shell-api\main dir

I would appreciate any good tip!

Thanks in advance

Mario
