Weird dependency behaviour...

[fa...@mpsa.com]

Hi Maveners,

I observe a strange behaviour when building the plugin I'm developing. Here
are the dependencies for which the build is OK :

            <dependency>
                  <groupId>org.apache.maven.reporting</groupId>
                  <artifactId>maven-reporting-api</artifactId>
                  <version>2.0-alpha-3</version>
            </dependency>
            <dependency>
                  <groupId>org.apache.maven</groupId>
                  <artifactId>maven-plugin-api</artifactId>
                  <version>2.0-alpha-3</version>
            </dependency>
            <dependency>
                  <groupId>oro</groupId>
                  <artifactId>oro</artifactId>
                  <version>2.0.7</version>
            </dependency>
            <dependency>
                  <groupId>commons-lang</groupId>
                  <artifactId>commons-lang</artifactId>
                  <version>2.0</version>
            </dependency>
            <dependency>
                  <groupId>commons-jelly</groupId>
                  <artifactId>commons-jelly</artifactId>
                  <version>1.0-beta-4</version>
            </dependency>
            <dependency>
                  <groupId>ant</groupId>
                  <artifactId>ant</artifactId>
                  <version>1.6.5</version>
            </dependency>
            <dependency>
                  <groupId>dom4j</groupId>
                  <artifactId>dom4j</artifactId>
                  <version>1.4</version>
            </dependency>

The plugin is compiled and installed, but can't run because it requires
other lib at runtime. So I add the following dependencies to make it work:

            <dependency>
                  <groupId>commons-beanutils</groupId>
                  <artifactId>commons-beanutils</artifactId>
                  <version>1.7.0</version>
                  <scope>runtime</scope>
            </dependency>
            <dependency>
                  <groupId>commons-jexl</groupId>
                  <artifactId>commons-jexl</artifactId>
                  <version>1.0</version>
                  <scope>runtime</scope>
            </dependency>
            <dependency>
                  <groupId>commons-jelly</groupId>
                  <artifactId>commons-jelly-tags-jsl</artifactId>
                  <version>1.0</version>
                  <scope>runtime</scope>
            </dependency>
            <dependency>
                  <groupId>commons-jelly</groupId>
                  <artifactId>commons-jelly-tags-xml</artifactId>
                  <version>1.1</version>
                  <scope>runtime</scope>
            </dependency>

I build again (the Java sources are not compiled this time because none has
been changed): the plugin is installed and runs perfectly.

However, if I clean my project (i.e. the generated classes are deleted),
and build again, then I get the following stacktrace :

The package "org.apache.maven.plugin.logging" seems to be missing this
time! How come?
I don't see where the problem comes from, as I only added dependencies for
runtime, and as those dependencies are not linked to other maven libs...

Any idea where this problem might come from?

Thanks!
