The error “Failed to get java version” while running Camunda 8 Run locally typically points to a Java environment issue. Here’s how you can troubleshoot it:

1. Check Java Installation

Run:

java -version

You should see something like:

java version "21.x"

Camunda 8 requires >=Java 17. Make sure that’s the version being used.

2. Check JAVA_HOME (This should solve your problem)

Ensure the JAVA_HOME environment variable is correctly set:

  • On Linux/macOS:

    • echo $JAVA_HOME

  • On Windows (in Command Prompt):

    • echo %JAVA_HOME%

It should point to your Java installation directory (e.g., /usr/lib/jvm/java-21-openjdk or C:\Program Files\Java\jdk-21).

3. Use the Right Java Version (Multiple Versions Installed?)

If multiple Java versions are installed, you may be accidentally using a different one. You can use:

  • Linux/macOS:

    *update-alternatives --config java

  • Or explicitly set the path:

export JAVA_HOME=/path/to/java21
export PATH=$JAVA_HOME/bin:$PATH

4. Check Permissions

Make sure the Java executable has execute permissions:

ls -l $(which java)

5. Logs for Details

Check the full stack trace or logs—sometimes Camunda Run outputs more info if you run:

./start.sh

or on Windows:

start.bat

If you’re still stuck, feel free to share:

  • The output of java -version
  • Your OS and how you installed Java
  • The exact Camunda 8 Run distribution you’re using (version + from where)
