Two things needed to get this to work;

• a tomcat user with the role manager-script in tomcat-users.xml
• specifying the url for deployment to something ending with manager/text.

That's it. See example conf for pom.xml below. And don't forget to use tomcat7:redeploy so you don't have to cycle undeploy/deploy.

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <url>http://your-server:8080/manager/text</url>
        <username>a-username</username>
        <password>a-password</password>
        <path>/a-path</path>
    </configuration>
</plugin>

I ran into a similar issue today - the 405 error can be caused by Tomcat not accepting PUT requests. This can be allowed by configuring Tomcat's web.xml (typically found in %TOMCAT%\conf\web.xml), and adding the following init-param:

<init-param>
    <param-name>readonly</param-name>
    <param-value>false</param-value>
</init-param>

You might also need to add an admin user to the tomcat-users.xml. See here for more details.
