Robert Baker commented on MPH-101:
----------------------------------
No - I am not able to reproduce this issue using maven-help-plugin-2.2 with the
attached pom.xml (modified to use the later version of the help plugin):
[INFO] --- maven-help-plugin:2.2:effective-settings (default-cli) @
test-artifact ---
[INFO] Effective-settings written to: C:\........\target\effective-settings.xml
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
It only appears to fail with maven-help-plugin-2.1.1.

> Running {{mvn help:effective-settings}} works fine whether or not there is a
> {{pom.xml}} in the project directory. However, if the {{pom.xml}} in the
> project directory includes a specific plugin configuration, then this command
> throws an error "An API incompatibility was encountered while executing
> org.apache.maven.plugins:maven-help-plugin:2.1.1:effective-settings:
> java.lang.NoSuchMethodError:
> org.apache.maven.settings.Settings.getRuntimeInfo()Lorg/apache/maven/settings/RuntimeInfo;".
> The plugin configuration that causes this error appears to be:
> {code:xml}
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-help-plugin</artifactId>
> <version>2.1.1</version>
> <configuration>
> <output>${basedir}/target/effective-settings.xml</output>
> </configuration>
> <executions>
> <execution>
> <phase>initialize</phase>
> <goals>
> <goal>effective-pom</goal>
> </goals>
> </execution>
> </executions>
> </plugin>
> {code}
> The failure does not occur with Maven 3.1.1, but does occur with Maven 3.2.3.
> To recreate the problem place the attached pom.xml into a directory,
> navigate to the directory and run the command {{"mvn
> help:effective-settings"}}.
