maven tomcat7:run terminates automaticatlly in eclipse - maven

Guys I know its very easy to run tomcat7 plugin in maven(in eclipse) but as I'm new to maven structure I can't figure it out that I was running maven build with "tomcat:run" and was working but I switched to maven plugin tomcat7 configured in pom.xml It starts it and stopped and gives build success msg. how change i make it keep listening?
Here my tomcate plugin settings
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<addContextWarDependencies>true</addContextWarDependencies>
<fork>true</fork>
<path>/</path>
<port>8080</port>
<httpsPort>8443</httpsPort>
<keystoreFile>C:/Users/Sohail Haider/.keystore</keystoreFile>
<keystorePass>apexsohail</keystorePass>
</configuration>
<executions>
<execution>
<id>start-tomcat</id>
<phase>pre-integration-test</phase>
<goals>
<goal>run-war</goal>
</goals>
</execution>
<execution>
<id>stop-tomcat</id>
<phase>post-integration-test</phase>
<goals>
<goal>shutdown</goal>
</goals>
</execution>
</executions>
</plugin>

Take into account the default lifecycle in maven
So, what you are doing in the configuration is starting and stopping tomcat when you are building the project. I think that you have a webapp project and want to run tomcat so you have to remove executions tag from the configuration and just execute mvn tomcat7:run

Maven plugin in not getting executed

I have a custom maven plugin but when i use that in my project pom , it does not get triggered !
Here is how i using same:
<plugin>
<groupId>com.autodeploy.maven</groupId>
<artifactId>my-docs-plugin</artifactId>
<version>1.0.2-0</version>
<inherited>false</inherited>
<executions>
<execution>
<id>myid</id>
<phase>install</phase>
<goals>
<goal>install</goal>
</goals>
<configuration>
<outputDirectory>target/doc</outputDirectory>
<custom-Folders>
<param>${basedir}/files/</param>
</custom-Folders>
</configuration>
</execution>
</executions>
</plugin>
I am triggering build cycle like mvn install:install or even mvn install ! None of these invoke my maven plugin !

Command line mvn parameter to stop spring-boot-maven-plugin from executing run

I'm developing a Spring Boot application and as part of the Integration Test phase of my maven project, I have configured the spring-boot maven plugin to start up and shut down during the pre and post integration test parts of the build as follows:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<id>pre-integration-test</id>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>post-integration-test</id>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
However, I did this just so that my developers can run their tests against a local instance of the service. On Jenkins, I would run the tests against an external service where I had deployed the service and I do not need the Spring Boot application to be spun up within the Jenkins job.
Is there a way for me to explicitly stop the spring-boot maven plugin from starting up the service via a mvn command line override?
Sure, you can expose a property for it, something like
<properties>
<skip.it>false</skip.it>
</properties>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<id>pre-integration-test</id>
<goals>
<goal>start</goal>
</goals>
<configuration>
<skip>${skip.it}</skip>
</configuration>
</execution>
<execution>
<id>post-integration-test</id>
<goals>
<goal>stop</goal>
</goals>
<configuration>
<skip>${skip.it}</skip>
</configuration>
</execution>
</executions>
</plugin>
Once you have that, run your command as follows: mvn verify -Dskip.it=true and the Spring Boot application will not be started as part of your integration tests.

maven javadoc generation issue of viewing on local tomcat server

I have managed to generate javadocs for my maven java project.
I use the following in
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<executions>
<execution>
<id>attach-javadocs</id>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<additionalparam>-Xdoclint:none</additionalparam>
</configuration>
</execution>
</executions>
</plugin>
I use the goal javadoc:javadoc when building.
Is there a way I can start my tomcat server and view the generated javadocs via a URL on my tomcat server? Something like localhost:8080/...
Thanks

test integration phase including jetty:run-war

I am still in a phase to create a POM.xml file. The basic is to start jetty plugin during the build life cycle. So far I have to enter
mvn package
mvn jetty:run-war
I do not want to do it manually. I prefer the way where a war file is created and jetty plugin started using the one command.
Here is my POM.xml
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.2.11.v20150529</version>
<configuration>
<scanIntervalSeconds>10</scanIntervalSeconds>
<webApp>
<contextPath>/hellojavaworld</contextPath>
</webApp>
<war>c:\apache-tomcat-7.0.64\webapps\hellojavaworld.war</war>
</configuration>
<executions>
<execution>
<id>start-jetty</id>
<phase>pre-integration-test</phase>
<goals>
<goal>run</goal>
</goals>
<!--configuration>
<daemon>true</daemon>
</configuration-->
</execution>
<execution>
<id>stop-jetty</id>
<phase>post-integration-test</phase>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
Why the jetty plugin is not started when inserted the following command?
mvn pre-integrate-test
What is the problem? The jetty plugin starts only when used the command
mvn jetty:run-war
From parent : mvn jetty:run-war -pl module
Solved.
The property of the jetty plugin for multimodule project si mentioned here: Multi-module Maven project and jetty:run
I had to specify the plugin and lifecycle configuration in the child pom.xml file. In the parent it was not working.
---Hellojavaworld-pom.xml (parent)
----app-pom.xml (child)
----jjav-pom.xml (child)

Maven tell plugin to not run during phase

Is there any phase I can use to prevent Maven from running a plugin goal or any other way I can tell Maven to skip a plugin goal?
Basically, I want to just run it manually.
<groupId>com.googlecode.maven-download-plugin</groupId>
<artifactId>download-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<phase >pre-integration-test</phase>
<goals>
<goal>wget</goal>
</goals>
</execution>
</executions>
<configuration>
<outputDirectory>${project.build.directory}/output</outputDirectory>
<url>http://some.url</url>
<outputFileName>filename</outputFileName>
</configuration>
</plugin>
When I use pre-integration-test it runs during mvn install. However, I just want to run it manually.
Phase none worked for my scenario to keep test-jars from being created for specific modules in my multi-module maven project. Like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>test-jar</id>
<phase>none</phase>
</execution>
</executions>
</plugin>
