maven-plugin

I am developing a new Maven plugin using API v3.1.1 because I need to upgrade to Maven 3.1.1, and need the Aether way of dealing with artifact repositories, among other things retrieving the complete list of artifact versions. I am using Eclipse Aether (0.9.0.M4), NOT Sonatype Aether. I have already read through http://wiki.eclipse.org/Aether and tried the demos http://git.eclipse.org/c/aether/aether-demo.git/tree/ , but I have not been able to understand why the following within a subclass of AbstractMojo doesn't work. Both RepositorySystem repoSystem , RepositorySystemSession repoSession ,

I want to develop a Maven plugin and also test it properly. I was reading the documentation on maven-plugin-testing-harness and trying things out for a few hours already. I'm constantly running into NoClassDefFoundError and NoSuchMethodError , I just can't figure out which dependencies I need. Here's my MCVE: https://github.com/highsource/hello-maven-plugin Right now I'm getting: java.lang.NoClassDefFoundError: org/apache/maven/plugin/descriptor/PluginDescriptorBuilder at org.apache.maven.plugin.testing.AbstractMojoTestCase.setUp(AbstractMojoTestCase.java:161) at junit.framework.TestCase

I receive this error when I try to run the maven goal - mvn eclipse:eclipse -Dwtpversion=3.3.1 [ERROR] Failed to execute goal org.apache.maven.plugins:maven-eclipse-plugin:2.8 :eclipse (default-cli) on project conference-web: Unsupported WTP version: 3.3.1 . This plugin currently supports only the following versions: 1.0 1.5 2.0 R7 non e. -> [Help 1] [ERROR] Will using version 2.0 suffice ? But should'nt the goal run successfully ? <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <configuration> <wtpmanifest>true</wtpmanifest> <wtpapplicationxml>true<

We've got a multiproject we're trying to run Cobertura test coverage reports on as part of our mvn site build. I can get Cobertura to run on the child projects, but it erroneously reports 0% coverage, even though the reports still highlight the lines of code that were hit by the unit tests. We are using mvn 2.0.8. I have tried running mvn clean site , mvn clean site:stage and mvn clean package site . I know the tests are running, they show up in the surefire reports (both the txt/xml and site reports). Am I missing something in the configuration? Does Cobertura not work right with

I am attempting to create an custom maven report to generate when I run the mvn site goal in my project. I have followed the instructions here: http://docs.codehaus.org/display/MAVENUSER/Write+your+own+report+plugin Specifically I have created a mojo that implements the appropriate methods, and its "executeReport(...) method is called when I run mvn site. I have also implemented a class that extends AbstractMavenReportRenderer, and filled out the renderBody(...) method with some calls to the methods in the sink. My Mojo returns a new instance of that custom renderer in its "getRenderer()"
