I am trying to publish my coverage report generated by Jacoco plugin - jacoco.exec. But I get the below exception with the mentioned sonar and Jacoco configuration.

SonarCube version 6.7.7

[ERROR] Coverage report 'jacoco.exec' could not be read/imported. Error: {}

Am I missing any configuration in sonar or jacoco?

Which goal do you call with maven? – Ima
This is mvn cmd mvn -B clean verify sonar:sonar -Dmaven.test.failure.ignore=true -DskipLongRunningTests=false -DskipOpticalInterfaceTests=true -Dorg.xml.sax.driver=com.sun.org.apache.xerces.internal.parsers.SAXParser -Dsonar.host.url=http://localhost:9000 -Dsonar.login=#### -Dsonar.analysis.mode=publish -Pjacoco – Seventeen

java.lang.IllegalStateException: Failed to parse JaCoCo XML report: jacoco.exec
...
Caused by: javax.xml.stream.XMLStreamException: java.nio.charset.MalformedInputException: Input length = 1

The error indicates that unsupported character is found when parsing XML, and the file is jacoco.exec. It is because jacoco.exec is binary, not xml.

In addition Sonar has deprecated the support of jacoco.exec.
I suggest you to follow coverage-test-data-importing-jacoco-coverage-report-in-xml-format. From the link above:

By default the generated report will be saved under target/site/jacoco/jacoco.xml; this location will be checked automatically by the sonar-jacoco plugin so no further configuration is required. Just launch mvn sonar:sonar as usual and the report will be picked up.

Thanks @samabce, I don't get the exception now while parsing the xml file by removing the deprecated tags ...But even on successful parsing of file ...I don't get coverage as 0% in sonarqube result though it has UT in it [INFO] 13:15:11.198 Sensor JaCoCo XML Report Importer [jacoco] [DEBUG] 13:15:11.204 Reading report '/udir/ragul/git/19/commons/access-commons-dao/target/site/jacoco/jacoco.xml' [INFO] 13:15:11.223 Sensor JaCoCo XML Report Importer [jacoco] (done) | time=25ms – Seventeen
I suggest to open a new question for this problem. – Burkley
