How to solve missing JAR files error from Ant

How to solve missing JAR files error from Ant

Hi,

I keep getting this error- 

```
Cause: the class org.apache.tools.ant.taskdefs.optional.ssh.SSHExec was not found.
         This looks like one of Ant's optional components.
Action: Check that the appropriate optional JAR exists in
-/usr/share/ant/lib
-/root/.ant/lib
-a directory added on the command line with the -lib argument
Do not panic, this is a common problem.
The commonest cause is a missing JAR.
This is not a bug; it is a configuration problem
```
while Im trying to run the following ant build step-

```
ant -lib /home/xyzsuite/root/.ant/lib/ -file ./tools/build.xml build
```

I did ant -diagnostics and it gave following results-

```

**Note- Im running this on a linux 8 arm64v8 server.**

Could you please help me with this, any ideas to solve this are highly appreciated
