Signing in Windows
Create a folder C:\signtool and copy signtol.exe and certificate to sign in that
Also create zimbra_code_signing.prop file which should contain this line - signcert.pass=<password for certificate>
Copy certificate and rename to zimbra_code_signing_cert.pfx, if you don't want to rename it then you can pass it as ant options as well like ant -f installer-ant.xml -Dsign.cert=C:\signtool\zimbra_code_signing_cert.pfx
Signing in Mac
Pass certificate name when creating installer
ant -f installer-ant.xml -Dosx_installer_cert=Developer ID Installer: Zimbra, Inc.
If you want to disable code signing then you use
ant -f installer-ant.xml -Dosx.dontsign=true
Development version
Above steps will build production version of Zimbra Desktop, which will not have developer tools to debug javascript code
If you want to create developer version then use below command
ant -f installer-ant.xml -Dnode-webkit.flavor=-sdk
