Incompatibility between Jacoco plugin and Jacoco 0.7.5

[Vincent Privat]

I have upgraded Jacoco to 0.7.5 from 0.7.4 and now face this error with Sonarqube (5.1.1, java plugin 3.3):

Hi Vincent,

This issue is resolved in next release 3.4 of Java plugin (see http://jira.sonarsource.com/browse/SONARJAVA-1091).

Hi,

See http://docs.sonarqube.org/display/PLUG/Usage+of+JaCoCo+with+Java+Plugin, "Java Plugin is not compatible yet with JaCoCo 0.7.5".
