Byte buddy maven plugin fails in modularized projects

[cavallium]

My project fails to run byte-buddy-maven-plugin because it has a module-info.java file in the sources.

<plugin>
	<groupId>net.bytebuddy</groupId>
	<artifactId>byte-buddy-maven-plugin</artifactId>
	<version>1.12.12</version>
		<executions>
		<execution>
			<goals>
				<goal>transform</goal>
			</goals>
		</execution>
	</executions>
	<configuration>
		<transformations>
			<transformation>
				<plugin>reactor.tools.agent.ReactorDebugByteBuddyPlugin</plugin>
			</transformation>
		</transformations>
	</configuration>
</plugin>

You are right, module-info should be skipped. I changed this on master and will release the fix with the next version.

@raphw Where can I find the documentation for this Maven Plugin?

[raphw]

Its a "plugin-plugin" and documented in the readme for the subproject.

`private static void transformHibernatePersistentCollection() {

    log.info("Transforming org.hibernate.collection.internal.AbstractPersistentCollection"
        + "#initialize()");

    new AgentBuilder
        .Default()
        .type(named("org.hibernate.collection.internal.AbstractPersistentCollection"))
        .transform(new AgentBuilder.Transformer() {
            @Override
            public DynamicType
                .Builder<?> transform(DynamicType.Builder<?> builder,
                                      TypeDescription typeDescription,
                                      ClassLoader classLoader,
                                      JavaModule module) {
                return builder
                    .method(named("initialize"))
                    .intercept(Advice
                        .to(ApplyEntityGraphOnInitializingPersistentCollection.class));
            }
        })
        .installOnByteBuddyAgent();
}`

I have this transformation which is being done during runtime. Is there a way to move this to compile time using the maven plugin ? Can you provide few examples ?

[raphw]

Unfortunately, no, unless within the Hibernate build. Build plugins can only transform your own classes.
