[Google Cloud] Upload Cron using Eclipse

1. Create cron.xml and put it on src/main/webapp/WEB-INF:

<?xml version="1.0" encoding="UTF-8"?>
<cronentries>
  <cron>
    <url>/tasks/summary</url>
    <target>beta</target>
    <description>daily summary job</description>
    <schedule>every 24 hours</schedule>
  </cron>
</cronentries>

2. And change pom.xml to:

<plugin>

<groupId>com.google.cloud.tools</groupId>

<artifactId>appengine-maven-plugin</artifactId>

<version>${appengine.maven.plugin.version}</version>

<configuration>

           <deployables>

             <param>target/appengine-staging/WEB-INF/appengine-generated/cron.yaml</param>

           </deployables>

                 </configuration>

</plugin>

  Note that cron.yaml is the output staging of cron.xml when deploying.

3. And run command below on Terminal for checking if the deployed works correctly:

mvn appengine:deploy -X

Why not using Eclipse to upload cron?

It seems it is Google Tools issues.
