can do without xmltask:
2. Add this file:
target name=read-replace-version
buildnumber /
property name=vers value=${build.number} /
replaceregexp match=versiongt;(.*)lt; replace=versiongt;$
{version.num}${build.number}lt; byline=true
I found the solution myself, I think is also nice for NetBeans
Configure the builders for the project, choose an tool type Ant
Builder
1. We take the Complete Build File (builder.xml) for Google App Engine
2. Add this file:
property name=version.num value=1.0./
taskdef name=xmltask
