[dgplug-users] How to resolve dependencies in rpmbuild command

[neeraj kumar]

Experts,

I am trying to get the rpmbuild for *tomcat8.5.40* Getting this issue on*
CentOS 7* where the rpmbuild is failing due to some dependencies.Want to
understand how to proceed?

Should I install the dependencies first or just downloading the dependent
rpms will do? If so, where would I keep the dependent RPMs so that rpmbuild
-bb tomcat.spec picks them?

-bash-4.2# rpmbuild -bb tomcat.spec
error: Failed build dependencies:
ecj >= 1:4.4.0 is needed by tomcat-1:8.5.40-1.el7.centos.noarch
