Answer 1

In the default maven lifecycle mvn deploy means to deploy one or more build artifacts to a maven repository. The reason is because the maven-deploy-plugin 's deploy goal is bound to the deploy phase of the lifecycle. This configuration is automatically done when you use for example packaging jar .

In maven

• a maven build lifecycle is made up of phases
• a phase is made up of plugin goals
• the packaging type (eg jar, ear, war) pre-configures plugins goals for execution in a lifecycle phase

In order to solve your problem I would first package the webapp and then invoke the deploy goal of the tomcat7-maven-plugin .

mvn package org.apache.tomcat.maven:tomcat7-maven-plugin:2.0:deploy

or simply

mvn package tomcat7:deploy

The mvn command above means:

• invoke the default build lifecycle until phase package
• then the goal deploy of the tomcat7 plugin.

If you want to know how maven resolves tomcat7:deploy to org.apache.tomcat.maven:tomcat7-maven-plugin:2.0:deploy you should read more about plugin groups and plugin naming conventions.

With maven deploy command, usually gets errors for various reasons. if you work in Unix/Linux system, I recommend using "rsync" method on console. (You can write own shell script to manage easily). It helps not only deploying without a problem but also helps to get time while redeploying (only uploading changed / new files). Because maven deploy / redeploy uploads your project as a bundle in jar/war. However "rysnc" method uploads your project files one by one.

Before using it, you should sure that two conditions.

1- your project is built in target folder (Spring Tool Suite)

2- you have access to tomcat via ssh

example code : (v_ : prefix which is variable(customizable))

rsync -avz v_your_project_in_target root@v_ip:v_tomcat_name/webapps/v_project_name
