Some time, we have installed multiple java version in Mac like Java 1.8 and java 11.0 and default version is java 8 but we are trying to start ant clean or ant all with above Hybris Sap commence 2205 version. We will have below error due to wrong java version.

Open Terminal in Mac and check java version using “Java -version” command. You can see above. its was expected java 11 in Hybirs 2205 but default set to Java 8 which is not compatibility that why there was build failed. You can refer to how to set default Java version.
