Key: MPH-101
URL: https://jira.codehaus.org/browse/MPH-101
Project: Maven Help Plugin
Issue Type: Bug
Components: effective-settings
Affects Versions: 2.2, 2.1.1
Environment: Apache Maven 3.2.3
(33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-11T16:58:10-04:00)
Maven home: C:\........\CommonFiles\apache-maven-3.2.3
Java version: 1.6.0_43, vendor: Sun Microsystems Inc.
Java home: C:\........\CommonFiles\Java\jre

Reporter: Robert Baker
Priority: Minor
Attachments: pom.xml
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:
<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>
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".
