The error message "dotnet sonarscanner did not find java but JAVA_HOME exists" indicates that the SonarScanner for MSBuild is unable to locate the Java executable even though the JAVA_HOME environment variable is set correctly. This can be caused by a few different factors, including:
- The Java executable is not in the PATH environment variable. The PATH variable is a list of directories that the system searches for executables when you type a command in the shell. Make sure that the bin directory of your Java installation is in the PATH variable.
- The Java executable is not a valid executable. Verify that the java executable is indeed a Java executable by checking its file permissions and file type.
- The Java installation is corrupted. Try reinstalling the Java installation to see if that resolves the issue.
Here are some steps you can try to resolve the issue:
- Check the PATH variable. Open a terminal window and type the following command:
echo $PATH
This will print the contents of the PATH variable to the console. Make sure that the bin directory of your Java installation is in the list of directories. If it is not, add it to the end of the PATH variable using the following command:
export PATH="$PATH:/path/to/java/bin"
- Verify the Java executable. Open a terminal window and type the following command:
file /path/to/java/bin/java
This will print the file type of the java executable. Make sure that the file type is "executable" and that the executable bit is set. If the file type is not "executable", try changing the file permissions using the following command:
chmod +x /path/to/java/bin/java
- Reinstall Java. Uninstall the current Java installation and then install a new one. Make sure to download the correct version of Java for your operating system.
