No JaCoCo analysis of project coverage can be done since there is no class files

Question

I am using Bamboo, SonarQube, and Maven plugin for generating the Jacoco Report in SonarQube. It is generating jacoco.exec file but how to display reports in SonarQube? Following plugin i am using '

<plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>

                            <!-- Sets the path to the file which contains the execution data. -->
                            <destFile>${project.build.directory}/jacoco.exec</destFile>
                            <!-- Sets the name of the property containing the settings for JaCoCo

Answer 1

build 08-Sep-2016 15:33:06 INFO: No JaCoCo analysis of project coverage can be done since there is no class files.

Like it said in the logs; check if you have specified following:

sonar.java.binaries=classes directory, most likely target/classes

Works better if you can also specify (it then should not complain about some classes not being found):

sonar.java.libraries=libraries directory, likely target/project/WEB-INF/lib
