Hi I’m try to run my Gatling simulation from jenkins pipeline and I’m getting a weird java error:

```auto
C:\Jenkins\workspace\WebTests\WebTesting\Gatling_LoadTesting\bin>gatling -s google 
GATLING_HOME is set to "C:\Jenkins\workspace\WebTests\WebTesting\Gatling_LoadTesting"
JAVA = "java"
Error: opening registry key 'Software\JavaSoft\Java Runtime Environment'
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.

```

```auto

```

```auto
Im trying to run the following in my pipeline in Jenkins

```

```auto

```

```auto
stage('LoadTest') {
            steps {
                node('Test01')
                {
                    dir('WebTesting\\Gatling_LoadTesting\\bin')
                    {
                        bat 'gatling -s google'
                    }
                }
            }
        }

```

```auto

```

```auto
This error only happens with I run it from Jenkins and works fine when I run it from a .bat,

```

```auto
Has anyone had this error before ?

```

Ahh is it because I need the JDK not the JRE ?
