Intellij: SDK 17 is not compatible with the source version 17

I am trying to get a project to build in IntelliJ but I keep getting an error. I have tried different JDKs such as the jet brains and OpenJDK but I always get this error

Everything I have seems to be pointing to java 17 so I feel a bit confused

Java compiler settings

I feel like it could have to do with my project layout?

Solution

  • Your maven.compiler.source and maven.compiler.target values are wrong.

    Replace 1.17 and set it instead to 17 per JEP 223.

    <maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
