Subject M2 : How to implement goals in SCM provider implementation ?
Date Mon, 05 Jun 2006 06:46:38 GMT
Emmanuel,
 
As you mentioned, pom corrected, but there is no breakthrough, not getting
any test result for the tag <scm> <scm> mentioend below in the test pom.
 
 How can I know, my main implementation class is instantiated ? 
 
Please suggest !
 
Regards,

Thanks Emmanuel, pom.xml is corrected, but at the first hand I would like to
know the following to get the better idea of the sequence of execution from
the entry point of the plugin : 

1.components.xml contains the entry point of the pluing ? If yes, in my case
main entry point mentioned is components.xml is MksScmProvider. 

It's the entry point of the provider. Maven-SCM find the provider to use
with the second token in the connection url that must be the role-hint of
one of the providers. 

                <component-set>

                  <components>

                    <component>
<role>org.apache.maven.scm.provider.ScmProvider</role> 
                      <role-hint>mks</role-hint>
<implementation>org.apache.maven.scm.provider.mks.MksScmProvider</implementa
tion> 
                    </component>

                  </components>

                </component-set>


so, in my view, this class is executed and chanin of methods also as called
from this only ? So, in my case it is not responding any error or something
irrspective of whatever I specify in : 
           <scm>

             <connection>scm:mks:"[EMAIL PROTECTED]@project"</connection>

         </scm>


Something else can be checked ? As I can see in case of other provider
implementations xpp3 (xml pull parser ? Do I have to tweak or change
something in this too ? 

If you don't have general settings that can be used by all scm connection,
you don't need to create a provider settings loaded by xpp3, depends on the
provider usage. A sample of parameter that can be general for the cvs
provider is the compression level to use for all commands.

Your pom is totally wrong. It must be:



<project>



         <modelVersion>4.0.0</modelVersion>

         <groupId>com.mycompany.mytestscm</groupId>

         <artifactId>testmksplugin</artifactId>

         <version>1.0</version>



         <scm>

             <connection>scm:mks:"[EMAIL PROTECTED]@project"</connection>

         </scm>



         <build>



             <plugins>

              <plugin>

                 <groupId>org.apache.maven.scm</groupId>

                 <artifactId>maven-scm-plugin</artifactId>

                 <version>1.0-beta-3</version>

                 <dependencies>

                    <dependency>

                       <groupId>org.apache.maven.scm</groupId>

                       <artifactId>maven-mks-provider</artifactId>
<version>1.0</version> <!-- it would be better to use 1.0-SNAPSHOT until the

release of it -->

                    </dependency>

                 </dependencies>

              </plugin>

             </plugins>



         </build>



</project>
