[m2e-users] Invoke plugin execution when files in src/main/resources change

[Ben Emery-Honzal]

Hello,

I'm trying to invoke my custom plugin "i18nMessageCompiler" whenever a 
properties file in the src/main/resources directory changes (e.g. when a new 
property is added). How do I configure the pom.xml or m2e to invoke the plugin 
whenever the properties file changes?

In the lifecycle-mapping, I configured the plugin to run on incremental build. 
One issue might be that Eclipse does not trigger an incremental build when 
files in src/main/resources change. However, even if I change a Java class in 
src/main/java (which should invoke an incremental build), the 
i18nMessageCompiler plugin execution does not get invoked.

Only a full project rebuild via Eclipse's > Project > Clean (with "Start a 
build immediately" checked) will invoke the plugin execution.


Excerpt from the project's pom.xml:
