sonar-cxx 2.x.y release compatible with Java 1.8

[rngh101]

Hi sonar-cxx plugin developers,

Is there a sonar-cxx 2.x plugin release which is compatible with a Java 1.8 version on the scanner side?

I have sonar-cxx 2.0.4 version plugin installed on SonarQube 7.9 server. However, my client side environment has Java 1.8.

When I trigger the sonar-scanner, it downloads the plugins from the server, and then stops abruptly throwing an exception saying that "The plugin [cxx] does not support Java 1.8".

I understand that either upgrading my environment to Java 11 or having a parallel Java 11 installation and using it to trigger the scanner will help.

But unfortunately, this cannot be done in some of my client environments.

Hence, I am looking for one of the following options if available:
a) Use a Java 1.8 compatible sonar-cxx plugin version
b) Any mechanism by which I can skip/exclude the sonar-cxx plugin from the scanner side?
c) Any mechanism by which I can control my server to not serve the sonar-cxx plugin when client tries to download it?

Thanks
Rajesh

Hello @rngh101,

Hi @rngh101,

a) Use a Java 1.8 compatible sonar-cxx plugin version

The plugin is developed and build with Java 11 dependencies. Only possibility I see is that you fork the plugin and build your own version with Java 8. We have no interest to do this because for SQ 9 Java 11 is also mandatory on scanner side and for most others Java 8 and Java 11 side by side on a PC is no issue (https://docs.sonarqube.org/latest/analysis/analysis-with-java-11/)

b) Any mechanism by which I can skip/exclude the sonar-cxx plugin from the scanner side?

Currently there is no possibility to exclude plugins, but SonarSource seems to work on it for upcoming releases: https://portal.productboard.com/sonarsource/3-sonarqube/c/158-remove-languages-from-an-instance.

c) Any mechanism by which I can control my server to not serve the sonar-cxx plugin when client tries to download it?

Same as above, I don’t know a solution. It’s also not possible to add a mechanism to the plugin because error happens already before entry point of plugin is called.
