C++ plugin causing an issue while running Java/python projects about sonar-cxx

[guwirth]

Hi @narayam,

Past 25 day sonarqube works fine with C++ plugin, but today we getting the above error for Java and python projects.

What has changed in your setup?

cxx plugin version: sonar-cxx-plugin-2.1.2.588.jar

Is not an official release. Last released version was 2.1.1 with https://github.com/SonarOpenCommunity/sonar-cxx/releases/download/cxx-2.1.1/sonar-cxx-plugin-2.1.1.488.jar. Please try again with this version.

Regards,

[narayam]

Hi @guwirth as you suggested I have updated the C++ plugin version 2.1.1.488. Its worked without any issue. But after a month, we are getting same issue.

Hi @narayam,

thanks for trying. What has changed in your setup? Sounds that SQ version, cxx version and config was stable?

Error is org.sonar.cxx.sensors.tests.dotnet.CxxUnitTestResultsAggregator in CxxPlugin.define

sonar-cxx/sonar-cxx-plugin/src/main/java/org/sonar/plugins/cxx/CxxPlugin.java

Line 110 in 484c9a5

l.add(CxxUnitTestResultsAggregator.class);

That’s one of the first steps loading the CxxPlugin, long before executing the plugin. Don’t understand why this sometimes is working, sometimes not?

Regards,

@narayam

• error during load/init of plugin

  sonar-cxx/sonar-cxx-plugin/src/main/java/org/sonar/plugins/cxx/CxxPlugin.java

  Line 110 in 484c9a5

  l.add(CxxUnitTestResultsAggregator.class);

• before loading/reading the configuration
• before executing a sensor/report

Can only be a problem with SonarQube version, cxx version, Java or environment.
