Unable to load processor

[ttben]

Hi there

I am trying to do a dead-simple example of spoon for teaching purpose and facing an Unable to load processor issue that I don't understand.

Context:

• maven project
• using spoon-core version 5.4.0 according to the official website
• using spoon maven plugin in v. 2.4
• executing mvn clean install command at the root of my project

Below, an extract of my pom.xml file:

<dependencies> <dependency> <groupId>fr.inria.gforge.spoon</groupId> <artifactId>spoon-core</artifactId> <version>5.3.0</version> </dependency> </dependencies>

` <build>
    <plugins>
        <plugin>
            <groupId>fr.inria.gforge.spoon</groupId>
            <artifactId>spoon-maven-plugin</artifactId>
            <version>2.4</version>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <processors>
                    <processor>fr.unice.test.spoon.processor.GTToLTProcessor</processor>
                    <processor>fr.unice.test.spoon.processor.LTToGTProcessor</processor>
                </processors>
            </configuration>
            <!-- To be sure that you use the latest version of Spoon, specify it as dependency. -->
            <dependencies>
                <dependency>
                    <groupId>fr.inria.gforge.spoon</groupId>
                    <artifactId>spoon-core</artifactId>
                    <version>5.3.0</version>
                </dependency>
            </dependencies>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
            <version>3.5.1</version>
        </plugin>

    </plugins>
</build>`

I don't understand why I need to specify a precompile option or to include something in the classpath since my processor are in the current project:

src/main/java/fr/unice/test/spoon/processor : GTToLTProcessor.java | LTToGTProcessor.java

I have found this issue that may be related or not.

I expected that mvn clean install will run my processors on all java files in classpath, and output the result in a specific folder.

Need help on this !

thanks !

The processors are in the same project as the code to be transformed? (this is not recommended)

Does it work with the precompile flag?

[ttben]

I tried to specify the precompile flag and it did not worked

About my maven project structure, I have now:

• parent pom, containing dependencies on spoon core, spoon plugin and processors
• a submodule containing processors
• a submodule containing sources to handle

Is that correct?

[monperrus]

that's better. and the second submodule must depend on the first one.

Ok thanks !
It is working :)
