Hi,

I am encountering the below issue on CentOS Linux release 7.9.2009 (Core)

# java -version

openjdk version “11.0.9.1” 2020-11-04 LTS  
OpenJDK Runtime Environment 18.9 (build 11.0.9.1+1-LTS)  
OpenJDK 64-Bit Server VM 18.9 (build 11.0.9.1+1-LTS, mixed mode, sharing)  
(reverse-i-search)`son’: stat /opt/scannerdir/^Cnar-scanner-4.5.0.2216-linux/jre/bin/java

# echo $JAVA\_HOME

/usr/lib/jvm/java-11-openjdk-11.0.9.11-2.el7\_9.x86\_64

# sonar-scanner

Could not find ‘java’ executable in JAVA\_HOME or PATH.

# 

Any clue? Thanks in advance. I look forward to hearing from you. Please let me know if you need any additional information.

Best Regards,

Kaushal

Hi Kaushal, welcome to the SonarSource Community!

It appears based on your pasted output that you downloaded the version of `sonar-scanner` that includes an embedded JRE yet you also have a separate JDK already installed. In this case, you may wish to use the `sonar-scanner` zip install that does not bundle another JRE.

Yet still, it should have succeeded. How exactly did you invoke `sonar-scanner` and from which directory? Did you add its `bin` directory to your PATH first [as our docs suggest](https://docs.sonarqube.org/latest/analysis/scan/sonarscanner/)? Is it being invoked directly or within another shell or script of some kind?

+1 on this.

I have the same issue on Ubuntu 18.04.5 LTS

**java -version**  
openjdk version “1.8.0\_282”  
OpenJDK Runtime Environment (build 1.8.0\_282-8u282-b08-0ubuntu1~18.04-b08)  
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode)

**echo $JAVA\_HOME**  
/usr/local/java/jre1.8.0\_281/bin

**sonar-scanner**  
“Could not find ‘java’ executable in JAVA\_HOME or PATH.”

I’m invoking sonar-scanner directly from the top level dir of my repo, and I have added the sonar-scanner `bin` dir to my PATH. No luck.

Any help would be great.  
Thanks

Turns out the error message is misleading. The real problem is the java executable that is included in sonar-scanner-#.#.#.####-linux/jre/bin/ needs execute permissions set. After running

`chmod 755 .../sonar-scanner-#.#.#.####-linux/jre/bin/java`

sonar-scanner was able to scan.
