Hi,
I want to enhance classes by new enhance-maven-plugin released in version 4.2.8.Final.
I try it with this maven pom.xml snippet
...

Code:

<plugin>
   <groupId>org.hibernate</groupId>
   <artifactId>enhance-maven-plugin</artifactId>
   <version>4.2.8.Final</version>
   <executions>
      <execution>
         <goals>
            <goal>enhance</goal>
         </goals>
      </execution>
   </executions>
</plugin>

...
but it's not working. There is error :
Failed to parse plugin descriptor for org.hibernate:enhance-maven-plugin:4.2.8.Final (D:\.m2\repository\org\hibernate\enhance-maven-plugin\4.2.8.Final\enhance-maven-plugin-4.2.8.Final.jar): No plugin descriptor found at META-INF/maven/plugin.xml -> [Help 1]

How to correctly configure and use it?

I found that plugin build by gradle generate wrong pom.xml and there is not required content for plugin in META-INF.
When I build project sources by maven with corrected pom.xml, then it is usable in my project but there are build errors.

So, this is my correct pom.xml :

You'll need to hook the plugin in with the compile phase.

<plugin>
<groupId>org.hibernate</groupId>
<artifactId>enhance-maven-plugin</artifactId>
<version>4.2.8.Final</version>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
</plugin>

Hi Jeremy,
problem is not in phase.
When I use EnhancementTask by maven-antrun-plugin on compile phase, code is enhanced with warnings.

Quote:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>Enhance domain classes</id>
<configuration>
<target>
<taskdef name="enhance"
classname="org.hibernate.tool.enhance.EnhancementTask">
<classpath>
<path refid="maven.compile.classpath" />
<path refid="maven.plugin.classpath" />
</classpath>
</taskdef>
<enhance>
<fileset dir="${project.build.outputDirectory}">
<include name="entity/*.class" />
</fileset>
</enhance>
</target>
</configuration>
<phase>compile</phase>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>

I don´t know how to attach the test project, so I can send you it by mail, if you want.
In output there you can see, that there is aspectj plugin used for compile time weaving, but without it, it is the same result.
