XML Error Validating appengine-web.xml

Question

I get this error when I try to deploy to Google AppEngine:

com.google.apphosting.utils.config.AppEngineConfigException: XML error validating /Users/matt/Documents/workspace/myapp222/war/WEB-INF/appengine-web.xml against /Users/matt/Downloads/eclipse 7/plugins/com.google.appengine.eclipse.sdkbundle.1.3.1_1.3.1.v201002101412/appengine-java-sdk-1.3.1/docs/appengine-web.xsd

My appengine-web.xml

    <?xml version="1.0" encoding="utf-8"?>
    <appengine-web-app xmlns="http://appengine.google.com/ns/1.0"&gt;
      <application>myapp222</application>
      <version>1</version>

      <!-- Configure serving/caching of GWT files -->
      <static-files>
        <include path="**" />

        <!-- The following line requires App Engine 1.3.2 SDK -->
        <include path="**.nocache.*" expiration="0s" />

        <include path="**.cache.*" expiration="365d" />
        <exclude path="**.gwt.rpc" />
      </static-files>

      <!-- Configure java.util.logging -->
      <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
      </system-properties>

</appengine-web-app>

What's wrong?

Answer 1

Caused by: org.xml.sax.SAXParseException: cvc-pattern-valid:
Value '0s' is not facet-valid with respect to pattern
'\s*(([1-9][0-9]*)([DdHhMm]|[sS]?))(\s+([1-9][0-9]*)([DdHhMm]|[sS]?))*\s*'
for type 'expirationType'.

<include path="**.nocache.*" expiration="0s" />

0s is not valid. You must specify at least 1s.
