Please follow the below steps to resolve the issue

1. From Anypoint studio goto Windows -> Preferences -> Installed JREs.
2. Here change the JRE (C:\Program Files\Java\jre1.8.0_162) to your JDK (C:\Program Files\Java\jdk1.8.0_162) and select the JDK checkbox and click Finish -> ok -> ok.

Now try to update the pom.xml file by Right clicking the pom.xml file Mule -> Update project dependencies.

If still you are facing the issue follow the another step as below:

1. Goto Windows -> preferences -> Installed JREs -> Execution Environment Here select JavaSE-1.8 and on right window click on the jdk1.8.0_162 [perfect match] and now try to Update project dependencies.

This will solve the issue.
