While installing the freemaker plugin using eclipse, there are some problems:
I searched for the installation method on the Internet, I use the online installation
I got this error when installing:
An error occurred while collecting items to be installed session context was:(profile=F__jee-neon_eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=). No repository found containing: osgi.bundle,org.jboss.tools.usage,2.2.4.v20170505-1848
Solution: After seeing the plugin installation prompt on the freemaker IDE official website, click "Install New Software" in eclipse, enter the warehouse address provided by the official website, and select Freemaker IDE under Jboss Application Development to complete the installation.
