Set Proxy for Force.com Migration Tool

When you  setup ANT and you believe it being setup correctly but still it still fail when you perform task, there are possibilities that your organization is using proxy.Example error that you receive when you run ant task.

Caused by: com.sforce.ws.ConnectionException: Failed to send request to https://
test.salesforce.com/services/Soap/u/39.0

 Here I list down of steps that I did to overcome this:

1. Ask Network team what is the proxy host and port in your organization.Is username and password is required?
2. Define proxy in target.In build.xml , create target name like below.

<target name="proxy">
        <property name="proxy.host" value="xx.xx.xx.xx" />
        <property name="proxy.port" value="xxxx" />
        <!--If there username and password required
  <property name="proxy.user" value="UserName" />
        <property name="proxy.pwd" value="Password" />-->
        <setproxy proxyhost="${proxy.host}" proxyport="${proxy.port}"  />
    </target>



3. Set depends to true for task that you going to perform.For example in given build.xml , I set depends for test and describeMetadata

 <target name="test" depends="proxy"><!--set depends here-->
      <!-- Upload the contents of the "mypkg" package -->
      <sf:deploy username="${sf.username}" password="${sf.password}" sessionId="${sf.sessionId}" serverurl="${sf.serverurl}" maxPoll="${sf.maxPoll}" deployRoot="mypkg" rollbackOnError="true"/>
      <mkdir dir="retrieveOutput"/>
      <!-- Retrieve the contents into another directory -->
      <sf:retrieve username="${sf.username}" password="${sf.password}" sessionId="${sf.sessionId}" serverurl="${sf.serverurl}" maxPoll="${sf.maxPoll}" retrieveTarget="retrieveOutput" packageNames="MyPkg"/>
    </target>

Another example, I set at describeMetadata task.

<!-- Retrieve the information on all supported metadata type -->
    <target name="describeMetadata" depends="proxy">
      <sf:describeMetadata username="${sf.username}" password="${sf.password}" sessionId="${sf.sessionId}" serverurl="${sf.serverurl}"/>
    </target>

Now when I run ant test , the result will be like this :

C:\salesforce_ant_39.0\sample>ant test
Buildfile: C:\salesforce_ant_39.0\sample\build.xml
proxy:
test:

Winmerge give me misguide message.

I am using Winmerge to compare code. For some reason, it give keep saying that the files are different while I really confident that I haven't touch the file.When I open the file , there no difference visibly shown which give me a little headache.

Turn out that I need to modify setting in Winmerge.Go to Edit, click on Options.

Now the view is better.
