I've explicitly stated process-resoures on this plugin, even though this is not necessary according to the documentation: http://alchim.sourceforge.net/yuicompressor-maven-plugin/usage_compress.html
When running:
mvn net.alchim31.maven:yuicompressor-maven-plugin:compress
It runs fine.
When running:
mvn process-resources
It doesn't run, even though an exec plugin I have on this phase does work.
Here's the relevant portion of my pom.xml:
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<executions>
<execution>
<phase>process-resoures</phase>
<goals>
<goal>compress</goal>
</goals>
</execution>
</executions>
Looks like a minor mistypo at least in the code that you posted.
Should be <phase>process-resources</phase>
not <phase>process-resoures</phase>
