Jenkins, ABE and Git Permission denied error while executing the build on Jenkin

Hi All,
I am getting below error while executing the build in Jenkins.

  • /opt/softwareag/webMethods912/common/AssetBuildEnvironment/ant/bin/ant -DSAGHome=/opt/softwareag/webMethods912 -DSAG_CI_HOME=/opt/softwareag/CI_scripts -DprojectName=BalaDemo build
    /var/lib/jenkins/workspace/BalaDemo@tmp/durable-82f59534/script.sh: line 2: /opt/softwareag/webMethods912/common/AssetBuildEnvironment/ant/bin/ant: Permission denied

I am not sure what I am doing wrong. Please let me know if anybody else faced the same issue.

Appreciate the help.
