Unknown packaging: sonar-plugin

Question

I need to build a sonar plugin. I am using maven to create project but I am getting error.

Project build error: Unknown packaging: sonar-plugin

my pom.xml is as below:

<?xml version="1.0" encoding="UTF-8"?>

Please provide me a solution.

Thanks in advance!

Answer 1

First of all: sonar-packaging-maven-plugin version 1.9 is available (you are using 1.7)

Within the plugin I developed I am using the following header. You could also try to use the parents in your pom. Do not know if this will fix the problem. If it does not, I could give you my pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>org.codehaus.sonar-plugins</groupId>
    <artifactId>parent</artifactId>
    <version>18</version>
  </parent>

  <artifactId> ....

EDIT 1: My pom.xml: Please make sure you edit all the TODOs I wrote for you. Please notice: I have deleted the license part within my pom, because I did not need it and saw no reason to use it:

<?xml version="1.0" encoding="UTF-8"?>
