Maven Overlay: Base project always starts tomcat on install - maven

Question

I have 3 projects: parent, base and demo.
Parent is for global plugins and dependencies:

Base is the basic Spring config (Servlet, Controller, ...):
<?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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>base</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<parent>
<groupId>com.example</groupId>
<artifactId>parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<build>
<defaultGoal>install</defaultGoal>
</build>
</project>
And demo is for Spring JSP Stuff:
<?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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>demo</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<parent>
<groupId>com.example</groupId>
<artifactId>parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<dependencies>
<dependency>
<groupId>com.example</groupId>
<artifactId>base</artifactId>
<version>0.0.1-SNAPSHOT</version>
<scope>runtime</scope>
<type>war</type>
</dependency>
</dependencies>
<build>
<defaultGoal>tomcat:run</defaultGoal>
</build>
</project>
Installing parent works like a charm (Can find it in the local m2 repository), but installing the base project always runs tomcat?! I just want to build the war and install it in the local m2 repository. What's wrong here?
ps: I don't like to always mention dependencies and plugins, so it would be great to leave them in the parent project as I need them in every child (e.g. demo) project.

Answer 1

Your defaultGoal is install and you bind tomcat-run on the pre-integration-test. So as soon as you launch maven install, it will execute tomcat-run while executing the pre-integration-test phase.
Checkout the maven lifecycle : http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html to understand.
So you should update your tomcat7-maven-plugin and remove the executions. If you still want to keep those, then you should think in using some profiles (a specific profile for building foe example)
