Why clover throws error "No Clover instrumentation done on source files" while instrumentation?

[Paritosh Srivastava]

Unable to instrument the source code on my java project with maven 3.6.3 and openclover-4.4.1

Hi Team

I am not sure why I continuously get the below error while trying to instrument the java source code.

 --- clover-maven-plugin:4.4.1:instrumentInternal (clover.inst) @ project1 ---

[INFO] No Clover instrumentation done on source files in: [/Users/paritosh/ABC/project1/src/main/java] as no matching sources files found (JAVA_LANGUAGE)

[INFO] No Clover instrumentation done on source files in: [/Users/paritosh/ABC/project1/src/test/java] as no matching sources files found (JAVA_LANGUAGE)

[INFO] 

I tried providing the exact path of the java file as well in the configuration but every time it threw the same error message. Even I tried the goal of maven clover:setup but it threw the same message.

Due to this, no clover database is getting generated hence there are no reports. 

  No Clover database found, skipping report generation

My project uses java 11. I read somewhere that there is no support for java 11 as of now but is there any upcoming plan for this.

Also, is the error which is coming up due to this java version? Is there any work around for now.

Code snippet from pom.xml:

<groupId>org.openclover</groupId>
                    <artifactId>clover-maven-plugin</artifactId>
                    <configuration>
                        <targetPercentage>10%</targetPercentage>                    <cloverDatabase>${project.build.directory}/clover/clover.db</cloverDatabase>
                       <debug>true</debug>
                        <includes>                                    <include>${project.source.directory}/</include>
                        </includes>
                    </configuration>
                    <executions>
                        <execution>
                            <id>clover.inst</id>
                            <phase>validate</phase>
                            <goals>
                                 <goal>instrument-test</goal>
                                <!-- <goal>setup</goal> -->
                            </goals>
                        </execution>

It would be really great if I can get some ideas on this. Please let me know if any other information is required.
