Known Issues

For an up to date list of known issues see the issue tracker.

  • only tested with Java 17: SonarQube nohup.log file item: Error: LinkageError occurred while loading main class org.sonar.application.App java.lang.UnsupportedClassVersionError: org/sonar/application/App has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0. To solve this download OpenJDK 17 and unzip it (http://jdk.java.net/archive/). Point with the JAVA_HOME environment variable to the Java 17 location.
  • In SonarQube, each file extension must be uniquely assigned to one programming language. When operating several C/C++ plugins in parallel, this must be taken into account during configuration. To avoid problems on a server with multiple C++ plugins, the CXX programming language sensor is disabled by default.
  • Ensure that a rule is enabled if you get no results. In new SQ versions the default profile is read-only. The cxx plugin does not enable rules for external tools per default.
  • Message: "C++ cannot be analyzed with current SonarQube edition. Please consider upgrading...". SonarQube issues this message when an input file with the file extension .c, .cc, .cpp, .cxx or .c++ is read in the Community Edition. Select "Dismiss permanently" to continue without the message.
  • the cxx plugin only supports the Standard Experience Mode only but can also be used in Multi-Quality Rule (MQR) Mode, for mapping see #2855
  • sonar.cxx.other.rules: Starting with SonarQube 9.x LTS, a plugin cache mechanism was introduced that only reloads a plugin and thus the rules of a repository if a change to at least one plugin is detected. A “change” can be if there is a plugin with a new PluginKey in the plugin directory. It also checks whether the hash value of a plugin package has changed. If a change is detected, the plugin and thus the repositories it contains are updated.
  • cxx-sslr-toolkit-x.y.z.jar is not a plugin. Do not copy it to the plugins folder. If the JAR file does not contain a SonarQube plugin, the following error message appears in the LOG file when the server is started: ERROR Web server startup failed java.lang.NullPointerException: Plugin key is missing from manifest.
