Chris Williams added a comment - 2014-03-03 19:24 Because I've had to work around this myself in the meantime, I use the following groovy postbuild script to achieve this: // Grab the API for Jacoco def b = manager.build; def action = b.getActions().find { it.getUrlName() == "jacoco" } if (action == null ) { // no Jacoco coverage, so nothing to do ! manager.listener.logger.println "Unable to get Jacoco Build Action on build, so bailing out" return ; } def publishers = b.getProject().publishersList; def jacocoPublisher = publishers.find { it.getDescriptor().getId() == "hudson.plugins.jacoco.JacocoPublisher" } // Collect the current "observed" values for coverage def line = action.getLineCoverage(); def clazz = action.getClassCoverage(); def method = action.getMethodCoverage(); def instruction = action.getInstructionCoverage(); def branch = action.getBranchCoverage(); // def complexity = action.getComplexityScore(); // Now let's set the new threshold minimums to last value! // Only set these values if the observed percent is _higher_ than the existing minimum threshold! def thresholds = action.getThresholds(); // Classes int percent = clazz.getPercentage(); manager.listener.logger.println "Observed class coverage: ${percent}%" if (percent > thresholds.getMinClass()) { manager.listener.logger.println "Increasing minimum threshold to observed value for class coverage" thresholds.setMinClass(percent); } // methods percent = method.getPercentage(); manager.listener.logger.println "Observed methods coverage: ${percent}%" if (percent > thresholds.getMinMethod()) { manager.listener.logger.println "Increasing minimum threshold to observed value for methods coverage" thresholds.setMinMethod(percent); } // Branches percent = branch.getPercentage(); manager.listener.logger.println "Observed branches coverage: ${percent}%" if (percent > thresholds.getMinBranch()) { manager.listener.logger.println "Increasing minimum threshold to observed value for branches coverage" thresholds.setMinBranch(percent); } // Lines percent = line.getPercentage(); manager.listener.logger.println "Observed lines coverage: ${percent}%" if (percent > thresholds.getMinLine()) { manager.listener.logger.println "Increasing minimum threshold to observed value for lines coverage" thresholds.setMinLine(percent); } // Instructions percent = instruction.getPercentage(); manager.listener.logger.println "Observed instruction coverage: ${percent}%" if (percent > thresholds.getMinInstruction()) { manager.listener.logger.println "Increasing minimum threshold to observed value for instruction coverage" thresholds.setMinInstruction(percent); } // Complexity //percent = complexity.getPercentage(); // if (percent > thresholds.getMinComplexity()) { // thresholds.setMinComplexity(percent); //} // We need to replace the publisher with a new instance that has updated minimums // HACK to work around bug in plugin where we don't have access to plugin classes. def c = Class .forName( "hudson.plugins.jacoco.JacocoPublisher" , true , manager.hudson.getPluginManager().uberClassLoader) def constructor = c.getConstructor( [ String , String , String , String , String , String , String , String , String , String , String , String , String , String , String , String , String , boolean ] as Class [] ) // make a new version of the coverage publisher with updated minimums def newPub = constructor.newInstance(jacocoPublisher.getExecPattern(), jacocoPublisher.getClassPattern(), jacocoPublisher.getSourcePattern(), jacocoPublisher.getInclusionPattern(), jacocoPublisher.getExclusionPattern(), jacocoPublisher.getMaximumInstructionCoverage(), jacocoPublisher.getMaximumBranchCoverage(), jacocoPublisher.getMaximumComplexityCoverage(), jacocoPublisher.getMaximumLineCoverage(), jacocoPublisher.getMaximumMethodCoverage(), jacocoPublisher.getMaximumClassCoverage(), Integer .toString(thresholds.getMinInstruction()), Integer .toString(thresholds.getMinBranch()), Integer .toString(thresholds.getMinComplexity()), Integer .toString(thresholds.getMinLine()), Integer .toString(thresholds.getMinMethod()), Integer .toString(thresholds.getMinClass()), jacocoPublisher.isChangeBuildStatus()) // Now remove the old version and replace with the new publisher with updated minimums publishers.replace(jacocoPublisher, newPub); // remove old and replace with new b.getProject().save(); // persist the change

Seán Dunne added a comment - 2014-12-16 15:55 I'd like to add my voice to this issue. IMO being able to enforce that unit test coverage does not regress is a key feature of a coverage plugin. Would love to see it implemented!
