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

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

The plugin has to implement one of incremental build APIs for this to work.  There are currently three: the legacy BuildContext (provided by org.sonatype.plexus:plexus-build-api), and couple of separate APIs provided by takari incrementalbuild [1] project. Personally I think @Builder annotation-based API [2] is the most promising, but it's also the most recent one still has some teething problems.

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.
