Hello,

Following “Geting Started Guide”, I’ve launched

mvn clean wildfly:deploy

and I’m getting the following compiling error (using java 13)

Any advice ?

Thank you

I had the same problem. Updating to the latest version of the maven compiler plugin did not work but adding this to the properties in pom.xml did:

```
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
```

Can you please explain where and how to modify the pom.xml?  
As far as understanding you, the pom.xml of the app-profile-jee-vanilla has to be modified…

Having also referred [Maven – Example: Injecting POM Properties via Settings.xml](https://maven.apache.org/examples/injecting-properties-via-settings.html) for help, but without success so far.

Allright, got it: POM.xml within the root of Keycloak Quickstarts needs a fix…
