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-
  • ```
