How to set version when deploying gae java?

问题

Since Intellij Idea IDE gae deployment plugin does not work, I have to use mvn appengine:update. It always deploy to version 1, ignoring version in appengine-web.xml.

How to set version with mvn appengine:update deployment?

回答1:

You can set it via a Maven property:

<properties>
    <appengine.appId>my-application-id</appengine.appId>
    <appengine.version>my-application-version</appengine.version>
</properties>

PS: I'm also setting the applicationId here, you don't necessarily need that.

Set the version in plugin property

<plugin>
    <groupId>com.google.cloud.tools</groupId>
    <artifactId>appengine-maven-plugin</artifactId>
    <version>1.3.2</version>
    <configuration>
      <version>2</version>
    </configuration>
  </plugin>
