Deploy maven war-project to tomcat

With maven it’s possible to deploy the current version of your webapplication (<packaging>war</packaging>) with one command!

mvn clean package tomcat:deploy-only

All we have to to is to define the tomcat-maven-plugin:

...
<packaging>war</packaging>
...
<plugin>
 <groupId>org.codehaus.mojo</groupId>
 <artifactId>tomcat-maven-plugin</artifactId>
 <configuration>
 <url>http://server[:port]/manager</url>
<path>/${project.build.finalName}</path>
 <update>true</update>
<server>tomcat_xyz</server>
 </configuration>
 </plugin>

You have to define username/password in your settings.xml:

<?xml version="1.0" encoding="UTF-8"?>
<settings 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/settings-1.0.0.xsd">

<servers>
<server>
<id>tomcat_xyz</id>
<username>admin</username>
<password>123geheim</password>
</server>
</servers>

</settings>

Check the tomcat-user.xml:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
 <role rolename="manager"/>
 <role rolename="admin"/>
 <user username="admin" password="123geheim" roles="admin,manager"/>
</tomcat-users>

If you  run the maven command you will see:

[INFO] [tomcat:deploy-only {execution: default-cli}]
[INFO] Deploying war to http://server:8080/foobar-1.0.0-SNAPSHOT-B20090710  
[INFO] OK - Deployed application at context path /foobar-1.0.0-SNAPSHOT-B20090710
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------

To get the version and a buildnumber in the context-path you must define the finalName and you must use a „buildnumber-plugin“, e.g.  buildnumber-maven-plugin or maven-timestamp-plugin:

<build>
 <finalName>foobar-${project.version}-B${buildNumber}</finalName>
 </build>
