Using a custom transformer with dependencies

If your custom transformer relies on dependencies, you can easily add them to the javassist-maven-plugin when you use your transformer in your project's build :

Suppose you have a project that will use the javassist-maven-plugin with a custom transformer com.example.MyTransformer and this transformer uses the maven dependency :

<dependency>
    <groupId>com.example</groupId>
    <artifactId>dependency</artifactId>
    <version>${dependency.version}</version>
</dependency>

Then, you can add this configuration to your project's build :

<plugin>
    <groupId>com.github.drochetti</groupId>
    <artifactId>javassist-maven-plugin</artifactId>
    <version>${javassist-maven-plugin.version}</version>
    <configuration>
        <includeTestClasses>false</includeTestClasses>
        <transformerClasses>
            <transformerClass>
                <className>com.example.MyTransformer</className>
            </transformerClass>
        </transformerClasses>
        </configuration>
        <executions>
            <execution>
                <phase>process-classes</phase>
                <goals>
                    <goal>javassist</goal>
                </goals>
            </execution>
        </executions>
        <dependencies>
            <dependency>
                <groupId>com.example</groupId>
                <artifactId>dependency</artifactId>
                <version>${dependency.version}</version>
            </dependency>
        </dependencies>
</plugin>
