How to add version number to WAR file using ANT

Question

I have a ANT build file in which I am creating a WAR file. In this ANT file I have added version information to the WAR file name. But what is happening is, versions number's major and minor are getting update same time. What I mean to say is the increment of major and minor should happen as 1.1.0 1.2.0 : : 1.9.0 2.0.0

But what is happening is

1.1.0 2.2.0 : : 9.9.0 10.10.0

My Ant code is

    <target name="war" depends="compile, sethostname, setcurrenttime, setdistdir_withversion">
    <echo>Load properties file</echo>
    <loadproperties srcFile="build_info.properties" prefix="current"/>

    <echo>Dist conf path : ${main.dist.dir}</echo>
    <copy todir="${main.dist.dir}/prop/conf" preservelastmodified="true">
        <fileset dir="${conf.dir}">
            <!-- <include name="**/*_server.xml"/> -->
            <include name="*_catalina_logging.properties"/>
        </fileset>

    <condition property="warfilename" value="${name}">
        <not>
            <isset property="warfilename"/>
        </not>
    </condition>

    <echo>Main Dist directory:${main.dist.dir}</echo>
    <echo>Dist directory:${dist.dir}</echo>
    <echo>WAR filename:${warfilename}</echo>
    <war destfile="${main.dist.dir}/${warfilename}.war"
          webxml="WebContent/WEB-INF/web.xml">
        <fileset dir="conf"/>
        <fileset dir="WebContent"/>
        <classes dir="${build.dir}"/>
    </war>
    <copy todir="${war.archive.dir}" preservelastmodified="true">
        <fileset dir="${main.dist.dir}">
            <include name="*.war"/>
        </fileset>
    </copy>
</target>

    <loadproperties srcFile="build_info.properties" prefix="current"/>
    <echo>Current build number:${current.build.major.number}.${current.build.minor.number}.${current.build.revision.number}</echo>
    <property name="warfilename" value="${name}-${hostname}-${current.build.major.number}.${current.build.minor.number}.${current.build.revision.number}" />
    <echo>WAR filename set : ${warfilename}</echo>

        <entry key="build.system" value="${hostname}"/>
        <entry key="build.time" value="${build.time}"/>
    </propertyfile>
</target>

<target name="revision">
    <echo>Revision</echo>
    <propertyfile  file="build_info.properties">
        <entry key="build.revision.number" type="int" operation="+" value="1" pattern="00"/>
    </propertyfile>

The problem is that the following target depends on the revision, minor and major targets which will result in all 3 numbers being incremented.

<target name="revision-deploywar" depends="revision, minor, major" description="Deploy application as a WAR file"/>

Usually the major number is manually incremented by the developer, while the minor number is incremented after a dist and the revision after a compile.
