Unable to start Liberty Profile from Command Line : failed to create task or type antlib:com.ibm.websphere.wlp.ant:server

I am trying to start WebSphere Liberty profile server (named WL_UAT_Server) 

<project basedir="." default="help" name="myProject" xmlns:wlp="antlib:com.ibm.websphere.wlp.ant">
      <target name="liberty-start">
        <wlp:server id="test" installDir="/opt/IBM/WebSphere/Liberty" operation="start" serverName="WL_UAT_Server"/>
      </target>
</project>

from following command:

ant -f /opt/myProject/build.xml "liberty-start"

but system is giving following error:

/opt/myProject/build.xml:144: Problem: failed to create task or type antlib:com.ibm.websphere.wlp.ant:server
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet

This appears to be an antlib declaration. 
Action: Check that the implementing library exists in one of:
        -/usr/share/ant/lib
        -/home/root/.ant/lib
        -a directory added on the command line with the -lib argument


Total time: 2 seconds

following the the output of ant -diagonstics command

I've tested the following build file on ant 1.7.1 and it works fine. I'm getting your error, if I remove wlp-anttasks.jar from ant\lib folder. So double check, if the file is there and is readable - correct permissions? Maybe you are running build from different user? Or maybe you don't have access to Liberty or server folder?

Check, if the same user can start server from command line using:

C:\IBM\WebSphere\wlp\bin>server start WLP_UAT_Server
Starting server WLP_UAT_Server.
Server WLP_UAT_Server started.

Here is my build.xml file

<project name="libertyTest" default="start-server" xmlns:wlp="antlib:com.ibm.websphere.wlp.ant">
    <description>
            description
    </description>
    <!-- set global properties for this build -->
      <property name="wlp_install_dir" value="C:/IBM/WebSphere/wlp"/>
      <property name="serverName" value="WLP_UAT_Server"/>

    <target name="start-server" description="description">
        <wlp:server id="wlp.ant.test" installDir="${wlp_install_dir}" operation="start" serverName="${serverName}" />
        <wlp:server ref="wlp.ant.test" operation="status"/>
    </target>

    <target name="stop-server" description="description">
            <wlp:server id="wlp.ant.test" installDir="${wlp_install_dir}" operation="stop" serverName="${serverName}" />
    </target>
</project>

It looks like you've missed the step of copying the wlp-anttasks.jar into your $ANT_HOME/lib directory. Alternatively, if you don't want to alter your ant installation, you can use the typedef task to load the Liberty tasks, for example:

<typedef resource="net/wasdev/wlp/ant/antlib.xml" 
       uri="antlib:net.wasdev.wlp.ant" 
       classpath="somewhere/wlp-anttasks.jar"/>
