Hi, I am Ravikumar. I came to get help form you. That is : I have four projects in my workspace. Three of them have sub projects also. I done successfully building the four projects individually with multiproject plugin. But my goal is: One of the four projects has some web applications. It depends on all the other projects. so, whenever I run the this project.xml it must run the all the neighbor projects and at last this project. That is my gaol. I try with reactor. In this we specified the neighbor projects project.xml in inclued attribute in maven:reactor. But it makes error with message A cycle was detected. My maven.xml file is: <?xml version="1.0" encoding="UTF-8"?> <project xmlns:j="jelly:core" xmlns:ant="jelly:ant" xmlns:define="jelly:define" xmlns:maven="jelly:maven"> <goal name="ravi" description="Clean all JDoppio components" prereqs="clean"> <maven:reactor basedir="D:\workspace" includes="**/project.xml,**/**/project.xml" goals="clean:clean" banner="Cleaning:"> </maven:reactor> </goal> </project> First of all I want to know: 1. We can solve this problem with maven:reactor. 2. If not please give me idea with little more information. Could you please give the solution for this? I am waiting for you solution .
