symbol: class ACLASSNAME

You have a maven project that compiles and installs just fine, but when run with the clover goals on it fails with the above error. The project is set up a little bit different, as the source is in two folders, src/main/java/core, and src/main/java/gen. The maven compiler plugin is configured to handle this as below:

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<configuration>

<includes>

<include>core/**</include>

<include>gen/**</include>

</includes>

<source>1.5</source>

<target>1.5</target>

</configuration>

</plugin>

Cause

Clover does not understand the above definition.

Resolution

The maven best practice is to use the build-helper-maven-plugin to add alternate source directories, instead of using <includes> in the maven-compiler-plugin.

Please remove the <includes> from the compiler plugin and add the following plugin definition to your build.xml:

<plugin>

               <groupId>org.codehaus.mojo</groupId>

                <artifactId>build-helper-maven-plugin</artifactId>

                <version>1.1</version>

                <executions>

                    <execution>

                        <id>add-source</id>

                        <phase>generate-sources</phase>

                        <goals>

                            <goal>add-source</goal>

                        </goals>

                        <configuration>

                            <sources>

                                <source>src/java/core</source>

                                <source>src/java/gen</source>

                            </sources>

                        </configuration>

                    </execution>

                </executions>

            </plugin>
