Use Java 17 for SonarScan in Bitbucket Pipeline to analyze C/C++ project

  • ALM used: Bitbucket
  • CI system used: Bitbucket Cloud
  • Languages of repository: C/C++


in our C/C++ project, we are using the sonar build wrapper and sonar scanner for code analysis. Both are running in a custom Ubuntu:18.04 Docker container, with XilinxSDK 18.03 used for building. Since all users of the scanner need to migrate their Java version to Java 17, I tried to go with the simple solution: install Java 17 and set the environemnt variable $JAVA_HOME to the output of the already set java.home variable via java -XshowSettings:properties -version 2>&1 > /dev/null | grep 'java.home', which in my case is /usr/lib/jvm/java-17-openjdk-amd64.
However, the scanner still uses Java 11.

Now I have two questions:

  1. How do I tell the sonar-scan routine to use the installed Java 17?
  2. Is it possible to split the build and scan into two separate steps, using separate docker images?
    (I tried this in a way by forwarding the log files the build wrappers log file outputs to the next step, but it failed. Do I need to forward some specific environment variables to the next pipeline step too or what was I missing?)

Here are the pipeline steps and the log output.

Pipeline steps:

- export SONAR_SCANNER_HOME=$HOME/.sonar/sonar-scanner-$SONAR_SCANNER_VERSION-linux
- export BW_OUTPUT=$HOME/.sonar/bw-output
- mkdir -p $BW_OUTPUT
- curl -sSLo $HOME/.sonar/$
- unzip $HOME/.sonar/ -d $HOME/.sonar/
- rm $HOME/.sonar/
- export SONAR_SCANNER_OPTS="-server"
- export PATH=/tools/Xilinx/SDK/2018.3/gnu/aarch32/lin/gcc-arm-none-eabi/bin:$PATH
- export PATH=/tools/Xilinx/SDK/2018.3/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin:$PATH
- curl -LsS >
- unzip -j
- ./build-wrapper-linux-x86-64 --out-dir $BW_OUTPUT make clean debug
- export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64
- sonar-scanner$BW_OUTPUT

Log output up until the warning regarding the deprecated Java version:
Command: sonar-scanner$BW_OUTPUT

WARN: The version of Java (11.0.3) you have used to run this analysis is deprecated and we will stop accepting it soon. Please update to at least Java 17.

Fortunately, I found a solution that works. Here is what I did:

  1. Update the scanner in use to version 5.0.1.
  2. Set the Java version to use via environment variable:

Step 2 however does not work without step 1. I tried and failed. Setting the javaHome variable with sonar-scanner version 4.2.0 does not work.

PS: If you, like me, find code where instead of using the environment variable SONAR_SCANNER_OPTS your predecessors used CLI options, you can take them as they are and concat them to the option above, like this: "SONAR_SCANNER_OPTS=Dsonar.<some_option>=<foo> Dsonar.<another_option>=<bar>".
